A circular saw. How dusty with it
The main stages of working with the tool:
- Set the minimum depth of cut by adjusting the blade downward.
- Fit the guide to the size of the part by measuring the length from the edge of the blade to the edge of the foot. Layout material.
- Make the initial cut 3-5 mm.
- Continue sawing without stopping all the way through the blade.
- Use duct tape at the cut to avoid chipping.
Device and principle of operation
The design of a circular saw is quite simple. The device can be manual, or stationary type, combined models are also found.
Regardless of the type, the equipment consists of a saw and a base plate. The last element is made from durable steel sheets or aluminum alloys. The main purpose of the circular saw is a precise and high-quality longitudinal spray of wood.
A circular saw
Cutting boards and bars is carried out by rotating the discs, which have special covers that protect against injury during the working process. The cutting part is triggered by a trigger. Circular equipment allows you to process large volumes of wood.
Circular machine
Stationary circular saws are equipment for daily use. Such professional machines are capable of processing a large amount of wood per day. They are quite heavy. than 10 kilograms and high power up to 2500 watts.
Circular machine
Circular machines are used mainly in production for industrial purposes. The cost of such a device is quite high. Some small models of circular equipment also have a stationary function. They are successfully used in home workshops.
Stationary models
The use of circular machines has its own operational features. To spray wood you need:
- Set the switch on the equipment to the off position. Only then can the cable be connected to the electrical network.
- Raising the handle, adjust and fix the cutting height of the disc according to the size of the material prepared for cutting.
- Check the position of the guide bar and saw blade. Their location must be parallel to each other.
- Launches the circular saw and slits the wood material. Spraying one board should be done with a single approach.
Using a stationary circular saw
After processing all the material, turn off the switch on the equipment, which stops the rotation of the blade, and disconnect the tool from the mains.
How to cut wood correctly with an angle grinder
Setting up the circular saw
Before starting work, you should:
- Put the disc;
- Make sure that it is securely fastened;
- Make sure that the protective cover opens freely and returns to its original position when the handle is released;
- Check the correct installation of the riving knife;
- Make sure the saw is working correctly, held it in the mode for 10 seconds without load.
It is quite easy to adjust the dust before work. This requires:
- Adjust the position of the guide slot on the table and disc with a caliper, align the guide slots on the blade. When checking the tooth in the front and back of the blade, the discrepancy should not exceed 0.05 mm
- Check the parallel stop with a groove or splines. Here the offset must also not be greater than 0.05 mm
- Align the riving knife with the blade so that it is on the same line as the blade. In case of a mismatch, a more accurate adjustment is achieved by rotating the washers
- Tighten the mounting bolts securely to protect the table and the machine from vibration
Types of working attachments
The choice of attachments for work depends on the volume and type of work being done. The following devices are used with a chainsaw:
- Drum debarker, which is necessary for removing bark from logs;
- Lightweight nozzle for cutting logs;
- Standard nozzle used for making boards.
A circular saw. High productivity and ease of use
The circular saw is the best option for the job. It has excellent performance and allows you to cut a considerable number of blanks in a relatively short time, and with high quality. In addition, such a saw allows you to make a longitudinal cut of the material, but you need to know how to spray the board along exactly.
One of the most important criteria when choosing a circular saw is the maximum cutting depth. On the market there are devices that cut materials with a thickness of 30 to 130 mm. That is, you can pick up a machine both for cutting only thin boards, and for sawing bars.
It is also worth paying attention to one cutting tool. Discs with a large number of teeth will provide a neat, high-quality cut, while the cutting speed will be low.
The advantage of sawing logs with a chainsaw
Spraying the boards can be done with tools such as a chainsaw and accessories designed to make the job easier. When choosing certain products, it is necessary to focus on the volume of the proposed work. Stationary sawmills are of high cost and are purchased only if you plan to organize a business to create boards.
The most accessible tool for work is a chainsaw. Such devices have several advantages over electrical ones:
- The chainsaw can be used anywhere, regardless of the presence of an electrical network;
- The tool is suitable for working in high humidity conditions;
- Professional chainsaws are much more powerful than electric ones;
- You can use the chainsaw continuously for an hour.
For sawing logs into boards together with a chainsaw, a special frame is used, which is attached to the device and allows you to create boards of the same thickness. You also need a device to secure the log in one position. In addition, you will need a guide.
Since household gasoline saws are NOT designed for heavy loads, professional tools should be used for sawing logs. When choosing, you should pay attention to devices with a capacity of more than 7 horsepower. Before work, the fixed frame is adjusted in accordance with the selected width of the boards. To create a frame, you can use the legs from a school desk or metal corners.
How to cut a board along
For joiners, boards and beams are the most common blanks, of which crafts and wood products are subsequently produced. And the first thing the material is exposed to. This is sawing into pieces of the desired length. At the same time, you should know how to cut the board exactly, because incorrect performance of this operation can spoil the workpiece or significantly affect the appearance, and not for the better.
At large enterprises, the problem of how to exactly cut a bar or board does not arise. Any serious production has high-precision equipment that performs this type of work. At home, you have to do with what is at hand. At the same time, you still need to be able to use the tool or equipment correctly in order to saw off the board correctly, and the cut turned out without flaws.
Note that many companies that sell boards and beams, Provide cutting services. And for this they use all the same specialized equipment, so the purchased material will be cut efficiently. But it is not always possible to use such a service, and it often happens that you only need to spray one workpiece.
Cutting the board at home
You can cut a board at home with tools and equipment such as:
- A circular saw;
- Hand saw;
- Angle grinder (“angle grinder“).
Each of these options has its own specifics, which is important to consider before starting work, that is, you need to know how to spray a bar or board with one or another tool so that the cut quality is acceptable.
Lighter
The nozzle for removing bark from logs is used due to the wedge transmission. Attachment takes place with straps. For this, special pulleys are used.
