Selection of the saw band tooth system

The manufacturers provide the saw bands with constant and variable tooth
systems. The important factor for selection of the tooth system is the length of the
cutting canal with respect to the size of the product.
BOMAR recommends variable tooth system for its band
saws.
5. Constant tooth system – the saw band has a constant tooth pitch all over its
length. This type is suitable for cutting solid materials.
6. Variable tooth system – tooth pitch is variable. Variable tooth system is used
for profiled materials and bundle cutting. Variable tooth pitch lowers vibration
of the saw band, increases service life of the saw band and quality of the cut
area.
In the table below the type of the tooth system depending on the sizes and profile
of the cutting material is advised.
Footnotes:
Z Z – teeth number on one inch S – tooth with zero angle of the teeth K – tooth with positive angle of the
p
teeth
Examples of the tooth system marking:
32 S – number „32" means 32 teeth per inch (constant tooth system),
letter „S" marks teeth with zero angle with respect to the band.
4–6 K – number „4–6" means 4 to 6 teeth per inch (variable tooth system);
letter „K" marks teeth with positive angle with respect to the band.

Saw band running-in

For reaching a full lifespan of the band we recommend performing a running-in.
Running-in: Perform a cut with the frame lowering speed at 50%. If vibrations occur
increase or decrease the band's speed.
