three tip CBN inserts for semi-finishing TNGA

Benefits of using CBN inserts
1. Can replace grinding operations, which reduces
    machining costs.
2. Dimensional stability, which is especially important in
    mass production. Minimizes the amount of scrapped parts.
3. “Green” approach, due to minimized usage of coolant.

There are a few guidelines to follow in order to achieve best results and high productivity when machining hard materials:

• CBN is characterized by hardness of 4500 HV.
   The high hardness of CBN enables it to machine hard materials
   at high speeds and feeds.
• Successful HPT (Hard Part Turning) demands not only suitable
   cutting tools, but also the right conditions, preparation
   and environment.
