When using tape machines for metal cutting, the main thing is the correct choice of the parameters of the tape plate: type, pitch width, size, and the size of the teeth collapse.
When using belt machines for metal cutting, the main thing is the correct choice of the parameters of the band saw: type, pitch width, size, and the size of the teeth collapse.
For each type of metal-cutting machine, certain parameters of the length and width of the band saw are strictly set.
Vertical type machines use saws of minimum dimensions, up to 6 mm.
Band saws are supplied to metal cutting machines in two versions: welded belts or finished coils.
Varieties of bimetallic webs for alloys and high-carbon steel, type M51; bimetallic webs for low-carbon and carbon steel, type M42; bimetallic webs for exotic and wear-resistant, heat-resistant and heat-resistant alloys, for example SP; carbide saws of the TST type for special and heterogeneous alloys, hard and difficult to process materials.
The right choice of a band saw is carried out according to the recommendation of the desired tooth pitch.
The pitch - TPI is determined by the number of teeth in one inch - 25.4 mm.
With a constant step, the same teeth are located at an equal distance.
It is better to cut thin-walled blanks with canvases with a constant pitch of a small tooth.
For large, large-sized blanks, webs with a constant pitch of a large tooth are optimal.
Variable pitch means alternating one inch with a constant pitch of small teeth and one inch with a constant pitch of large teeth.
Variable pitch gives a wider cutting range, reduces noise and vibration of the machine.
It is optimal for cutting metal.
The cutting capacity increases the more the fewer teeth the blade has.
Increasing productivity at a large step increases chip formation.
This cutting method is optimal for soft materials.
