Today, belt machines are used in modern mechanical engineering, which provide high-performance and high-quality metal cutting.
Today, band saws are used in modern mechanical engineering, which provide high-performance and high-quality cutting of such metals: non-ferrous, titanium, nickel, and other alloys, as well as other structural and high-alloy steels.
With the help of belt machines, pipes, shaped profiles and solid rolled products are cut into size.
A band saw, which is welded into a ring and put on pulleys, is a cutting tool for metal cutting machines.
Unlike conventional processing methods using disc cutting, gas cutting machines, and mechanical hacksaws, the operation of band saws has a number of significant advantages that provide higher productivity and, due to the small thickness of the cut, contribute to a significant reduction in material consumption.
The high cost of ribbon webs pays off due to good performance, excellent durability with optimal selection and use for certain types of materials that are processed, and the sizes of the cut workpieces.
A feature of working with belt machines is the selection of a certain pitch of the teeth of the web, depending on the profile of the workpiece subject to sawing.
Each manufacturer provides catalogs with special tables for choosing the step of the canvas.
Thanks to them, the necessary step of the web is determined for sawing various types of sections.
It is also possible to calculate the pitch of the web by eye so that 3-4 teeth are in contact with the workpiece during the cut.
To cut blanks with different cross sections and diameters, it is necessary to have a pair of canvases with different steps in stock, which necessarily change during the change of blanks.
Advantages of band saw machines for metal: High level of cutting accuracy: from 0.1 to 1.5 millimeters, deviation from the vertical can be up to 0.05 millimeters; High-quality cutting surface; Cutting width goes up to 1.5 millimeters, which significantly saves metal; Can be cut at an angle up to ± 60 degrees; Can cut packages of blanks; Blanks of all kinds: long products, solid blanks and pipes.
