Quality homemade angle grinder. Makeshift angle grinder How to make an angle grinder out of an electric screwdriver

Since the invention of the angle grinder, the popularity of this tool is only increasing. This tool has a lot of advantages, so it remains in demand in various areas and sectors of life. The disadvantage of the standard angle grinder is the fact that it is not designed for work with miniature parts. Such a problem has been solved by the release of mini grinders.

If you can not buy a tool, then the mini angle grinder can be made your own.

Why do you need the smallest angle grinder?

Angle grinder angle grinder angle grinder of the standard type differs from the mini angle grinder in size, but otherwise the functionality is almost the same.

Small angle grinder is mainly used in such areas, where work with small parts is performed. In contrast to the standard-sized grinder, when working with which you need to hold it with two hands, then with the mini angle grinder everything is much easier.

The tool is lightweight, so the operator can hold it with one hand while his other hand holds the workpiece.

Mini-tools are used mainly by jewelers, where the smallest precision in the manufacture of various small parts is important.

This tool can be used when carrying out repairs of watches, electronics, small parts. Designed mini angle grinder for cutting metal, plastic and wood products.

Demand for them occurs even in everyday life, when it is necessary to grind, sharpen or saw a small part.

Important to know! If there is a need to use the mini angle grinder, it is not necessary to buy it. To make it simple enough, besides, for manufacturing requires a minimum set of components.

How to make a mini angle grinder yourself?

In order to make yourself a mini angle grinder, you need the main element. an electric motor.

It can be found in old cassette recorders, battery-operated machines, you can order it on the Internet, buy it in radio stores, or find it in the attic or garage.

As a power element of such a motor can be used batteries, rechargeable batteries or a power supply from a cell phone (power supply). The main thing that the voltage and current source suitable motor.

Two wires should be taken out of the motor, which will supply power for its functioning.

Depending on the size of the motor, you need to find the appropriate diameter of PVC pipe, or a tube of something else. Inside which the device will be placed.

The shaft of the motor unit should protrude from the pipe. In the tube, you must also leave room for the power supply and the switch.

Important to know! The electric motor inside the tube should be well fixed, otherwise when you try to saw something, it will move or rotate inside the housing.

To plug the back of the used pipe housing, you can use the appropriate pipe plugs (if you used standard PVC pipe) or make up a cover yourself. You should also cut two holes on the housing or in the back cover:

  • To install the button for starting and stopping the apparatus under construction.
  • For the electric motor shaft speed controller. Such a regulator in its finished form can also be removed from an old tape recorder.

It is recommended to place the button and the regulator so that the mini angle grinder could be conveniently turned on and off with one finger.

If the device will run on batteries, then you must provide for the installation of a removable cover, by which the replacement of batteries will be carried out.

If the product will operate from the mains power supply, you can solder the appropriate socket for its connection to the housing.

It is recommended to equip the electric motor shaft with a collet clamp. This will allow you to use in a homemade machine all kinds of disks, drills, and various special accessories from drills. The collet mechanism can be found in stores that specialize in the sale of power tools or spare parts for electronics.

Special disks for work on the mini angle grinder can be purchased or make your own by cutting them out of a large disc.

Such mini angle grinder is not suitable for cutting metal of great thickness, but is quite suitable for cutting plastic, wood and other materials.

These are such simple actions can make the necessary apparatus, saving money and time that you would spend searching for factory tools.

If your work is professionally associated with the need to use a mini angle grinder, it is better to find and buy the factory version.

Pros and cons

The advantages of homemade products can be attributed only to cost savings, as almost all components for the manufacture of a mini angle grinder can be found in the garage. Unlike professional mini-gritters, which are equipped with all the necessary attachments in the kit, in the homemade angle grinder such accessories are excluded, so they will need to buy or make their own.

The disadvantages of mini angle grinder can include the fact that in most cases it uses a low-power motor, while the professional models are more powerful and reliable motors.

In conclusion, it should be noted that if there is a need to purchase a mini angle grinder, it is worth giving preference to models of reputable manufacturers.

The main advantage of the mini-tool is its compact size, which allows you to perform work even in the most hard-to-reach places.

If a person by duty has to often face the need to process small or miniature parts, then he must necessarily have a mini angle grinder. We advise to read the article about the self-made mini drill.

Support structure and minor refinements

Almost always such an angle grinder is done as a stationary tool, so be sure to prepare a working surface. Suitable for any wooden or metal tabletop, whereby metal has the undisputed advantage.

The working platform is bent out of reinforcing ribless rod 12 mm or steel strip (2-3 mm). Externally, it must be completely repeat the contours of the used model, t.к. maximum fixation must be ensured during immersion. Usually use 4 transverse strips to form a contour and 3 perpendicular to them for rigidity. The joint is made by means of electric arc welding.

After such a bowl is installed on the table, it must be tightened tightly to the surface with bolts with nuts (bolts only with flat caps). Fixation must be sufficiently rigid, so at least 4 mounting points.

At the very end, the tool is turned over and lowered into place (handle upwards). The final fixation is made at the expense of clamps, which pull everything together on 2 sides.

If you have to work long hours with the tool, then make a protective cover. To do this, just make a piece of sheet steel and bend its edges so it occupies the entire space above the work area. For fixation to the tool to make a clamp out of a steel strip (exactly the size of the drill) and fix it with his own hands.

The angle grinder from the drill is made easier than the other way around. Angle grinder or angle grinder (angle grinder) has become an indispensable electro due to the wide range of work that can be done with it, but it has its own drawbacks, which interfere with the work. With it you can not always get to hard to reach places, and it often has a high unregulated speed, by the way, because of this requires increased safety measures. But, in spite of all this for certain it is irreplaceable. We can take advantage of all the advantages of the angle grinder, yes, we can also bypass its disadvantages. For this we will need to get hold of the drive shaft with flanges from the angle grinder (I took it from the old, spoiled).

angle grinder from the drill in the photo explanations

1 Drive shaft 2 Inner flange 3 Outer flange 4 Wrench for outer flange 5 Metal cutting disc

Assemble in the following sequence

Slide the inner flange onto the shaft so that it fits into the grooves and then screw the outer flange.

Tighten only the outer flange with the special wrench and hold the shaft with the open-end wrench on the inner flange.

To work we install a cutting (or other) disc

After installation, tighten and install in the drill chuck, also well tighten the shaft in the chuck.

Done! Since the drill is reversible, the working rotation must go clockwise, as when drilling. The arrows (in the photo) indicate the mandatory direction of movement of the disk in which case the outer flange with internal (usual right) thread will be self-tightening and will not unscrew during work.

Drawings of the stand for the angle grinder

There are not many drawings of such stands on the internet. Basically these are primitive sketches, illustrating rather the principle of operation of the device than the exact dimensions and the order of its assembly. And even those that are available, do not have all the necessary information.

And the very design of such devices quite often causes doubts in the application of such a drawing without some correction.

Therefore, we advise you not to waste time looking for them, and after carefully considering the options of implemented projects to create homemade racks for angle grinder, choose a suitable one for yourself. Or, taking into account their shortcomings, to realize their own.

General procedure for making the fixture

First, the metal is taken, and the plate is cut out of it. Then a corner is made from the resulting plate. To do this, first a triangular notch is made, and then the workpiece is bent at an angle of 90 0.

Six holes with notches are made in the metal plate. Holes are necessary for screwing self-tapping screws into them, with which you can install the corners and the handle. Holes in the holes are needed for the screws. The optimal size of the elements of fasteners. 335 mm.

Then the metal corners are installed. It is important at what angle the first corner is bent. It must be bent at an angle of 60 0. Otherwise the construction can not be fixed. When the corners are installed, the tools are attached to them.

To make the parts of the construction and the instrument fit together, there are bolts with nuts on one side and a handle on the other side. Bolts and nuts are needed to prevent the screw of the structure itself from unscrewing when cutting the metal.

To make the parts of the structure and the tool itself connect, use bolts with nuts on one side and a handle on the other. Bolts with nuts are needed to prevent unscrewing the screw of the design itself when cutting metal.

The stand for the angle grinder with their own hands. an overview of options

To mount the angle grinder on the console are suitable threaded handle mounts on its head. There. 3, and this is more than enough for a reliable fixation.

And sometimes for the mounting of the angle grinder engage sufficiently rigid and reliably mounted on its head protective casing.

For small angle grinders working with disks up to 125. 150 mm, sometimes mounting of the body to the console with strong clamps will be sufficient, but to prevent axial rotation of the tool, the thrust pad of the head of the grinder must be engaged.

angle grinder, working with cutting discs of large diameter (200. 230 mm), in addition to their secure attachment to the console, must have a good support base fixing the console itself to the work table.

This ensures minimal deflection from the cutting plane.

Many self-makers provide oscillating motion of the console by installing one or two bearings for its attachment to the work table. Readymade bearing units from cars or bicycles are often used for this. However, a simple bolted connection also provides sufficient mobility, the parts of which, if well lubricated, will work as conventional plain bearings.

This is how it is shown in the video describing the uncomplicated design of the stand for the metal angle grinder:

True, we would not rely on such a secure fixation of the tool in the upper position, as the author of the video recommends, but we would install the tension spring in a convenient place.

It is clear that repair of such bracket fixation comes to bolt replacement or, in extreme case, to simple increase of its diameter or installation of bushing in case of heavy wear of mating parts.

A similar principle of ensuring compliance with the flatness of the cut is ensured when making the rack not from angles, but from profile pipes. Watch a short video about a simple homemade metal rack for the angle grinder:

Few people dare to make a wooden rack for an angle grinder, but that doesn’t mean you can’t make one. But some of the designs that we want to show you may well serve as source of ideas for you to create a stand of your own design, in t.ч. and from this material.

Sometimes to ensure that the tool returns to the upper position after making the cut, instead of the tension spring, use a normal counterweight to compensate for the weight of the tool itself.

Mini angle grinder with their own hands

The need for a miniature tool exists where a person is engaged in the manufacture of souvenirs, model ships and aircraft, small technical units and parts.

Miniaturization is carried out in two variants. The first variant envisages fabrication of miniature tools only. disks, milling cutters, etc.д. The second variant involves exactly the construction of grinding tools on the basis of miniature motors.

The first option. Using a drill

The first option has a simpler solution. Let’s say we need to make a miniature grinding wheel, which will be installed in a drill or an electric screwdriver. For this we can take a broken disc.

On it with a caliper we draw a circle with the required dimensions. Then we cut out a future miniature disk on the circle which we have drawn. In its center we drill a hole in which we insert a bolt with a diameter of 6 mm.

Put a washer on the bottom and tighten it with a nut.

The bolt will be the axis of rotation of the disk. We insert it into the chuck of the drill or electric screwdriver and clamp. Such a tool can cut materials in hard-to-reach places or with small dimensions. You can grind finished parts.

It is not difficult to make a miniature cutter for cutting small plastic or wooden parts. For this we take an ordinary tin stopper from a glass bottle. In the center of it we make a hole to install the axle. The axis can be the same bolt with a diameter of 6 mm. Level the edges of the plug and cut out the teeth. It is desirable to make a minimal marking.

Such a cutter, loaded into a drill or an electric screwdriver, can easily cut small wooden slats, for example, for modeling. Plastics also lend themselves to this uncomplicated tool.

The second option. Self-Assembly (2 videos)

If the task is to make a miniature tool with your own hands, then you must first select the electric drive. As the electric drive is suitable motor from various devices. printer, old cassette recorder or from an ordinary electrified children’s toy.

Depending on the power of the electric motor you can build a mini angle grinder in two directions. The first direction is to use a mains power supply. For example from an old cell phone. The second direction is a fully autonomous model of the motor, which will be powered by batteries or rechargeable batteries.

The difference between the two directions is in the design of the housing. In the first case, you need space only for the electric motor, and in the second case you must install the battery compartment.

For the body is very convenient to use a piece of PVC pipe. If its diameter is slightly larger than that of the motor, you can wrap electrical tape around the motor. A glue gun can be used to fasten the motor.

You can use the plugs that are put on PVC pipes during transportation and storage as stopping plugs. In the front cap it is necessary to make a hole under the motor shaft, and in the back under the power wire. You must attach the power connector and the on/off switch to the body.

The ideal option would be the ability to mount some kind of collet clamp on the shaft. This will allow the use of standard burs, drills and non-standard mini cutters and disks. If you can not install the collet clamp, you can connect the shaft and the cutting tool with a double contact from the electrical pad.

In a similar way, you can make a case for a mini angle grinder with self-powered. Only after the motor is installed in it, it is necessary to install the battery pack. Wires from the batteries will be connected through a switch installed on the housing.

In both cases, you can use both homemade tools and standard industrial tools. burs and drills. on mini grinders.

How to make a mini angle grinder with their own hands from improvised means

Such a device as a small angle grinder is needed when the engraver has to deal with small parts, for example, in the manufacture of souvenirs. And yet, how to make a mini angle grinder with your own hands? There are two options for this.

The first option. using a drill

This option is simple enough. For example, you need to build a small circle for grinding, which will later be installed in a drill. Take an old or broken disc, mark an even circle on it, using a caliper. Cut out the shape. In the center you need to drill a hole and insert a bolt with a diameter of 6 mm. Put a washer on the bottom and secure everything with a nut.

The same bolt that we put in the center of the circle will be the rotation axis of the entire disk. The bolt is attached to the socket of the drill and tightly clamped. Done, now safely grind your parts.

The cutter for cutting small parts is easy to make. Take a metal stopper, which can be found on a glass bottle, and make a hole exactly in the middle. As an axis you can use the same bolt with a diameter of 6 mm. Unfold the edges of the plug and cut off the uneven teeth. It is better to make a marking.

Such a cutter will work well if you charge it into a drill. The device will cut small wooden or plastic parts with ease.

The second option. the full assembly of their own hands

How to make a mini angle grinder by yourself from beginning to end? If such a difficult task is set, then first you need to determine what will serve as the electric drive for the device. Power can be supplied from a small motor from various devices. such as an electric toy.

Depending on what power you need a mini angle grinder, its manufacture can proceed in two directions. In the first case, a mains power supply will be used, and in the second case. the device will be completely autonomous through the use of batteries or a small battery.

Such devices will have a different appearance. A self-contained unit will require an extra battery compartment.

As the body of a mini angle grinder is easy to use PVC pipe. In the case when the tube is larger in diameter than the motor, you can wrap it with duct tape and attach it to the body, using a glue gun.

As plugs you can use ordinary plugs that are put on the same PVC pipe. A through hole is made in the front stopper for the shaft, and in the back one for the wire. You need to install the power connector on the housing. the on/off button.

Machine for cutting circles from metal

Usually on the basis of the angle grinder make cutting machines. There are a dashing pond of these self-made machines on the internet. On our site, too, many ideas on this topic, and we will not repeat.

But a machine for cutting circles from sheet metal is a really cool idea.

With the help of a home-made device you can cut circles of different diameters. Quickly and easily. In general, the homemade device is definitely worth your attention.

As the body of the mini angle grinder is easy to apply the tube of PVC. In the case where the pipe is larger in diameter than the motor, you can wrap electrical tape around it and attach it to the housing, using a glue gun.

As plugs you can use ordinary plugs, which are put on the same PVC pipe. A through hole is made in the front plug for the shaft, and a hole in the back plug for the wire. On the housing you need to install the power connector. the on/off switch button.

If it is possible to fix a collet clamp on the shaft, then such a homemade device will be an ideal solution. Reception will ensure the use of standard drills and non-standard cutters and disks. In case the collet clamp installation is not possible, you can connect the cutting tool and the shaft by means of a double contact from an electric pad.

The body for a miniature home-made angle grinder, which works in stand-alone mode, is made in the same way. In this case, when installing the battery, you can not forget about equipping the battery block. The wires from this unit are connected using a switch that will be mounted on the housing of the unit.

In both cases, and in the other case, you can use homemade tools or standard, industrial drills and burs on mini grinders, assembled by your own hands.

Mini angle grinder: features of making a self-made machine

Since the invention of the angle grinder, the popularity of this tool is only increasing. This tool has a lot of advantages, thanks to which it remains in demand in various areas and branches of life. The disadvantage of the standard angle grinder is the fact that it is not designed to work with miniature parts. Such a problem has been solved by the production of mini grinders. If you can not buy a tool, you can make a mini angle grinder yourself.

Why you need the smallest angle grinder

Angle grinder angle grinder angle grinder of the standard type differs from the mini angle grinder in size, and otherwise the functionality is almost the same. The small angle grinder is mainly used in areas where work with small parts is performed. In contrast to the standard-sized grinder, during the work with which you need to hold it with two hands, then with the mini angle grinder everything is much easier. The tool has a low weight, so the operator can hold it with one hand, and the second to hold the part.

Mini-tools are used mainly by jewelers, where the smallest precision in the manufacture of those or other small parts is important. This tool can be used when carrying out repairs of watches, electronics, small parts. The mini angle grinder is designed for cutting metal, plastic and wood products. They are in demand even in everyday life, when it is necessary to grind, sharpen, or saw a small piece.

Important to know! If there is a need to use the mini angle grinder, you do not need to buy it. To make it simple enough, moreover, for the manufacture requires a minimum set of components.

How to make a mini angle grinder?

In order to make yourself a mini angle grinder, you need a core element. an electric motor. Get it you can in old cassette recorders, in the car running on batteries, you can order on the Internet, buy in radio stores, or find in the attic or the garage. As a power element of the motor can be used batteries, rechargeable batteries or a power supply from a cell phone (power supply). The main thing that the voltage and current source suitable for the motor.

From the motor necessary to derive two wires, through which will be the supply of power for its operation. Depending on the size of the motor, you need to pick up the appropriate diameter of PVC pipe, or a tube of something else. Inside which the device will be placed. The motor shaft should protrude from the tube. Space should also be left in the tube for batteries and a switch.

Important to know! The electric motor inside the tube must be well secured, otherwise when you try to cut something off, it will slide or rotate inside the housing.

To plug off the back of the casing tube you can use the appropriate pipe plugs (if you used standard PVC pipe) or make up a cover yourself. You should also cut two holes on the body or in the back cover:

  • For installing the button for starting and stopping the apparatus being constructed.
  • For the motor shaft speed regulator. Such a regulator in finished form can also be removed from an old tape recorder.

It is recommended to place the button and the regulator so that the mini angle grinder was convenient to turn on and off with one finger. If the device will run on batteries, then you must provide for installation of a removable cover, which will be used for battery replacement. If the product will operate from the mains power supply, you can solder the appropriate socket for its connection to the housing.

We recommend to equip the electric motor shaft with a collet clamp. This will allow the use of a homemade unit, all kinds of disks, drills and various special accessories from drills. Collet mechanism can be found at stores that specialize in the sale of power tools or spare parts for electronics.

Special discs for working on a mini angle grinder can be purchased or made by cutting them out of a large disc. Such a mini angle grinder is not suitable for cutting metal of great thickness, but is quite suitable for cutting plastic, wood and other materials. With such simple actions you can produce the necessary device, saving money and time you would spend on searching for the factory tool.

If your work is professionally connected with the need to use a mini angle grinder, it is better to find and buy the factory version.

Pros and cons

The advantages of self-made products can only include cost savings, as almost all components for the manufacture of mini angle grinder can be found in the garage. Unlike professional mini-gritters, which are equipped in the kit with all the necessary attachments, in a homemade angle grinder such accessories are excluded, so you will need to buy or make them yourself.

The disadvantages of mini angle grinder include the fact that in most cases it uses a low-power motor, while the professional models are more powerful and reliable motors.

In conclusion, it should be noted that if there is a need to purchase a mini angle grinder, it is worth giving preference to models by well-known manufacturers. The main advantage of the mini-tool is its compactness, so you can perform work even in the most remote places. If a person has to deal with the need to process small or miniature parts ex officio, then he must have a mini angle grinder. We advise to read an article about a self-made mini drill.

Manual electric circular saw on wood. Characteristics of choice

The electric circular saw has a special place among the tools today. Simple, lightweight and convenient device for working in various conditions, among other things, is also the most technically complex, combining:

make, mini, angle, grinder, their

And therefore, when choosing a circular saw there will always be difficulties in choosing the most appropriate parameters for the tool.

Device

The circular assembly saw has the following components:

  • base;
  • motor body;
  • protective cover fixed;
  • saw blade;
  • protective sliding cover;
  • adjusting devices;
  • Handle with trigger and locking button;
  • front stop handle;
  • The parallel guide;

Parameters of the machines

Classification of circular saws today, although conditional, but allows you to classify the tool more clearly in relation to the tasks that can be performed with this tool.

The main indicator in classifying this equipment is the diameter of the saw blade used in the saw and, consequently, the thickness of the material being cut:

  • small class (40-50 mm). sheet materials, work “on the spot”;
  • medium class (50-65 mm). the most common, universal;
  • professional equipment class (65-140 mm)

Depending on the cutting depth the power of the motor and electronic components of the tool are selected for the tool.

An important point when choosing is the weight of the equipment, because often you have to hold the tool with one hand, and to get a straight cut, you must also observe the safety rules, because the high speed of the saw if not held correctly can play a fatal role.

Types of equipment by functionality

Considering a handheld electric saw as a universal tool, it should be understood that the greatest role in the functionality of this type of tool is played by the base plate.

For almost all kinds of saw models, these features are inherent in the basic equipment today:

These basic parameters are largely similar for all kinds of both household copies and heavy professional models, but here we should take into account that:

  • Cutting depth adjustment requires a rigid fixation, and if the motor and the saw are lifted high above the plate surface, it causes vibration that requires a lot of effort to hold the tool;
  • The possibility of cutting at an angle in professional models is implemented in a more accurate scale of degrees, with a more rigid fixation of the selected parameter;
  • the functionality of professional models is expressed in the possibility to fix the saw permanently to a surface, thus obtaining a full-fledged circular saw.
  • when choosing equipment of approximately the same class and similar in technical parameters, preference should be given to models with a platform made of aluminum casting, such platforms are more stable, and less prone to deformation;
  • the next selection criterion should be the nodes of fixation of the saw position, it is the quality of these nodes that will largely depend on the quality of the results of the work.

Details

A very important, without exaggeration, place in any circular saw is the node of the circular saw’s attachment to the shaft. Different fastening options implemented in different models are mainly reduced to the use of various nuts. both regular hexagonal shape, and special, for a special key.

In the process of replacing the drive, uniquely a positive detail will be the shaft stopper, used to lock the shaft while clamping the nut, similar to what is in the grinders.

Saws depending on their power

Depending on the diameter of the circular saw blade the saw engine power is also calculated. Conventionally, today’s models are divided into the following classes:

Such classification allows not only to choose a necessary circular sawblade, but also to ensure a proper work of the equipment. shallow cutting depths, certain types of materials, especially plastic, require low-speed saws or models equipped with a speed regulator.

Additional saw functions

For professionals who know how to perform complex work, a manual wood circular saw in addition to the usual types of work and materials can be successfully applied:

Construction of a circular saw

To ensure maximum safety when working with a circular saw machine, it is recommended to bolt the table to the floor. The table top should be as thick as possible. To increase the degree of strength, you can cover it with thin metal sheets. This will also increase sliding of the workpieces and make the work more comfortable. The main difference between the machine and the table type of construction is that the angle grinder is mounted not above the table, but under its surface.

Self-tapping screws, clamps and other specially prepared parts are used for reliable fixation. The slot in the table top should also be about 4 mm on each side of the circular saw blade. If necessary, the machine can be equipped with guide elements made of bar, secured with self-drilling screws.

It is very easy to make a circular grinder from an angle grinder. It is important to observe safety rules. The machine should preferably be equipped with a protective plexiglass. Feed other blanks with other blanks. Remember that the lower part of the disk must rotate toward the master. Do not stand in line with the circular saw, because at very high RPM it can slip off. During work, the master must be as vigilant and careful as possible.

For almost all types of saw models, today, such functions are inherent in the basic equipment:

These basic parameters are largely similar for all kinds of both household copies and heavy professional models, but here we should take into account that:

  • the possibility of cutting at an angle in professional models is implemented in a more precise scale of degrees, with a more rigid fixation of the selected parameter;
  • the functionality of professional models is also expressed in the possibility of stationary attachment of the saw to any surface, obtaining a full-fledged circular saw.
  • when choosing equipment of approximately the same class and close technical parameters, preference should be given to models with a platform made of aluminum casting, such platforms are more stable, and less prone to deformation;
  • the next selection criterion must be the knots fixing the position of the saw, and it is the quality of these knots that will largely determine the quality of the results of work.

A very important place in any circular saw is, without exaggeration, the circular saw’s attachment unit to the shaft. Implemented in different models, the various options for fastening are mainly reduced to the use of various kinds of nuts. both the usual hexagonal shape, and special, under a special key.

When replacing the blade, a shaft stopper is a distinctly positive element that is used to lock the shaft while clamping the nut, similar to what is used in cigar cutters.

Types depending on the capacity

Saw motor power is calculated in accordance with the diameter of the blade. Conventionally, today’s models are divided into the following classes:
