Keep by manufacturer specified recommendation for adding the anticorrosive agents,
the antifreezes or other agents! For mixture of two different mixes can produce toxic
and aggressive mixes, which can threaten your health or damage cooling system of the
machine
2.15. Check machine function
Check, if the machine or some parts of the machine were not damaged during
transport.
Check, if covers are installed and functional. Check by means of the Tenzomat if the saw
band is correctly stretched. If it is necessary, you can stretch the saw band according to
chapter
Selection and replacement of the saw band . Values of the saw band stretching are
on the Tenzomat. Switch on the main switch and check the motors and systems (saw
band drive, hydraulic pump, cooling pump, chips conveyor).
Open and close the main vice. Turn the saw frame of the band saw from one outer
position to other outer position. Raise the saw frame to the top position and drop the
saw frame to the lowest position.
Start the machine with the cooling pump and let it run without load until the cooling
system will be filled with cooling liquid. As soon as the cooling liquid starts to escape
from the nozzles of the cooling system, the cooling system is ready for the operation.
Carry one cycle of cutting without material. Check, if the machine runs with no
irregularities. If all machine functions are right, the machine is ready for operation..
2.16. Saw band
Refit the saw band cover only after you have installed and tightened the saw band.
2.16.1. Saw band size
2720×27×0,90 mm
2.16.2. Selection of the saw band tooth system
The manufacturers provide the saw bands with constant and variable tooth system. The
important factor for selection of the tooth system is length of the cutting canal with
respect to the size of the product.
1. Constant tooth system – the saw band has parallel tooth pitch all over length. This
way is suitable for cutting of solid material.
2. 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 cutting area.
In tables, there are advised type of the tooth system depending on sizes and form of
the cutting material.
Footnotes:
Z
p
Z – teeth number on one inch
S – tooth with zero angle of the teeth
K – tooth with positive angle of the teeth
Examples of the tooth system marking:
32 S – number „32“ means 32 teeth on one inch (that means constant tooth system),
letter „S“ marks teeth with zero angle of the tooth.
4–6 K – number „4–6“ means 4 till 6 teeth on one inch
(that means variable tooth system); letter „K“ marks teeth with positive angle of the
teeth
BOMAR recommends use variable tooth systém.
