Currently, the field of application of band saws is quite wide.
They are used both at large industrial facilities, in construction, and in private farms.

To increase the productivity of saws and extend their service life, the blade and teeth of the saw are covered with special high-tech materials.
To date, there are many coatings, each of which has specific characteristics.
Types of band saw coatings Diamond coating The hardest coating for band sawing is a diamond coating with a granular structure designed for cutting any materials and alloys.
It is produced in seven standard grain sizes.
The coating structure can be continuous — for cutting small blanks; segmented — for cutting medium—sized blanks; intermittent - for cutting large blanks.
Carbide-tungsten coating This carbide coating is not inferior to diamond in its cutting qualities.
Carbide-tungsten band saws easily cope with those materials, the cutting of which leads to rapid grinding of the teeth of conventional band saws: hard, abrasive, fibrous and combined materials.
Titanium nitride (TIN) coating To protect the cutting edge of the band saw from overheating and premature wear, the tooth surface is coated with a durable and hard aluminum-titanium nitride coating.
Such saws do not require pre-running.
Finishing of band saws The operational wear resistance and productivity of the cutting tool largely depends on its proper running-in.
The edge of the teeth of the new saw is very sharp, whereas in order to avoid microscopes and to obtain optimal results, it is necessary that it acquire a rounded shape with a minimum radius.
To do this, the tool is run-in: for 15 minutes, the saw operates in a mode half the required power.
Thus, the loss of the sawn material is minimized.
