Compressor Industry
Cutting for the main and auxiliary bearings (flanges) need large
amount of CBN inserts. Because the intermittent situation is
lighter, it is easier to replace the alloy and carbide inserts.
The machining efficiency is much higher than carbide inserts,
and the tool life of CBN inserts is about 5 to 6 times than carbide
inserts.
