The principle of operation of a band saw for metal

The efficiency of the technique depends on the power of the engine driving the pulleys. This is considered an important criterion to consider when choosing the type of blade. Vertical or horizontal metal band saws are safe. This is because the cutting blade moves away from the workpiece. The product cannot be thrown into the direction of the user. Working on a metal band saw follows the following principle:

  • After turning on the equipment, the belt starts to move. You can send the workpiece to the machine and start cutting it.
  • The cuts are carried out due to the equal distribution of pressure on the metal, which helps to obtain accurate cuts.
  • Cutting can be done perpendicularly or at an angle not exceeding 60 °.
  • To obtain the desired cut, change the position of the canvas, turn the frame or the table itself.

How to choose a metal band saw?

Before purchasing expensive equipment, it is important to consider its further purpose. Any band saw for metal, professional or for household needs, must provide not only the necessary cut, but also protect the operator. Correctly selected elements of the machine will extend its service life. The working blade for a band saw for metal can be made:

  • Carbon steel. Designed for cutting various alloys.
  • Made of bimetallic materials. Applicable for special operating modes.
  • Made of carbide elements. Used for cutting iron castings and joints that contain a lot of titanium and nickel.
  • Diamond coated. Work in progress on abrasive materials.

Bandsaw Applications for Metal

If we focus on performance, it should be noted that modern designs are clearly superior to disk counterparts. The durability and strength of band saw machines for metal are ensured by the constant supply of materials to the cutting zone. The equipment is used for:

  • Processing of metal sheets along a complex contour with an unclean cut, because these joints in the future will be welded into different structures. Movement can repeat different shapes.
  • Cutting straight and angular shapes on steel rods, pipes, profiles of different types of cross-section.
  • Cutting workpieces from metal and their alloys with different technical characteristics.

  • Gravity band saw for metal Pegas 220-250GH-R. The device is used for piece and small-scale production. The frame of the machine lowers its own weight. The device can carry out perpendicular and angular cutting

DIY metal band saw

The purchase of special equipment is not affordable for many craftsmen. For such people, it will be useful to know how to make a band saw for metal with your own hands. For work, preparation of tools and materials is required:

  • old bike;
  • jigsaw;
  • plywood 1.5 cm thick;
  • wooden beam;
  • bearings;
  • studs, washers, screws;
  • shafts;
  • brass bushings with internal thread;
  • electrical tape.

It is worth making a band saw by adhering to the following steps:

  • Assembling a frame that acts as a table top. A bar for the pulleys is attached to it. In addition, an electric motor is installed there.
  • Manufacturing and installation of belt-driven pulleys that are mounted inside the cabinet.
  • Installation of the cutting blade and guides. The tape is mounted on pulleys. The guides are located on the side where the saw teeth are missing.
  • Finishing, commissioning and final check of the structure’s performance. The upper pulley is covered with a casing, which increases the level of safety during the operation of the equipment.

Installing blade guides

So that the saw cuts the material evenly and the tape does not push through, guides are installed on a narrow beam along the blunt saw end. A common version of the device consists of three bearings located on the bar, one of which lies on the flat side of the canvas, the other two support it from the sides. Sometimes on the sides, instead of bearings, they put limiters made of wood.

Align the guides at the pivot point so that there is no vertical deflection at the opposite end, for convenience, the position of the beam is marked with the canvas stretched out.

Working on a band saw for metal

In the conditions of small-scale production, only metal band saws can cope with the tasks of cutting a variety of rolled products. Therefore, they are an indispensable attribute of many procurement industries. Today, we will dwell on the parameters of band saws, talk about the device and manufacturers.

The process of soldering the cutting strip

Soldering in the workshop is as follows:

  • the places at the junction of the canvas are polished from both ends, a brass strip is placed between the surfaces;
  • to make a strip, a piece of brass (0.3-0.4 mm) is cut along the width of the saw blade, moistened and sprinkled on both sides with borax powder;
  • the sponges of the mites are heated in an accessible way (gas burner or forge) to a bright red color, applied to the adhesion site and pressed;
  • the strip heats up from hot sponges, brass melts and spreads, and borax works in the form of a flux, which prevents soldering from oxidation when heated;
  • the pliers are not removed until the joint has completely cooled and the solder has hardened, after they are removed, the adhesion site is moistened with a wet hardening sponge;
  • inspect the joint, its hardness must correspond to the canvas;
  • if the junction is solid, then the heating procedure with ticks is repeated until the appearance of a straw-colored adhesion, gradually cooled;
  • a soft adhesion requires one more incandescent heating with tongs and a more abrupt cooling;
  • so that the sponges of the mites are not soldered to the saw strip in the process, a solution of chalk with liquid glass is applied to their contact surfaces;
  • for installation and tension on the lower and upper pulley, a handle is used, the correct position on the disks and rollers of the stop is checked by rotation, the correct passage is adjusted;
  • turn on the unit for a short time and additionally adjust it if necessary.

Types of saws depending on the work with the material

The following division into categories is made according to the processing material:

  • for stone;
  • for metal;
  • for wood;
  • for synthetics.

Working with hard materials (metal, stone) is carried out with a tool in which the working saw blade is reinforced with heavy-duty teeth from the corresponding alloys. The wrong choice of the saw blade leads to its breakage and deterioration of the edges on the workpiece being cut. Before buying a saw, determine the front of further work.

The Ultimate Guide To Metal Cutting Saws. From Hobby to Pro!

Band saws are high-performance equipment that allows you to cut curly and straight contours. The working tool is a flexible steel belt, closed in a ring, equipped with a row of teeth on one edge.

Aggregates began to be widely used only at the end of the 19th century, despite the fact that the first patent for a saw was obtained back in 1808 by an English designer. Then, in the coming years, such inventions were registered in France and the United States. The reason for such a dislike for the band saw was the inability to accurately connect the cutting blade.
