Dapra Corp., Bloomfield, Conn., now offers its advanced HBN Ball Nose inserts with helical cutting edge in metric sizes ranging from 10mm to 32mm in diameter.
The HBN inserts' helical cutting edge optimizes performance in Ball Nose finishing applications, offering smoother cutting action, reducing chatter and providing a cleaner surface finish. The HBN geometry is capable of heavier cutting and increased metal removal while lowering stress on work materials. Another advantage of the helical cutting edge is the longer tool life that results from reduced tool pressure and heat generation.

- chatter
chatter
Condition of vibration involving the machine, workpiece and cutting tool. Once this condition arises, it is often self-sustaining until the problem is corrected. Chatter can be identified when lines or grooves appear at regular intervals in the workpiece. These lines or grooves are caused by the teeth of the cutter as they vibrate in and out of the workpiece and their spacing depends on the frequency of vibration.
