Halnn CBN Inserts with Chipbreaker

Excellent chip breaking performance, avoid chip winding the workpieces or the tool, ensuring good surface quality and the tool life.

Halnn CBN Inserts with Chipbreaker CBN Inserts without Chipbreaker processing status CBN Inserts with Chipbreaker processing status

Without Chipbreaker With Chipbreaker

Different chips with same cutting condition by CBN inserts with or without chipbreaker

Halnn CBN Insert with Wiper

With same feed, obtain higher surface quality.

With same roughness, can be used for large feed, reduce the time on each component, improve the process efficiency.

Note: It can be used for Profile machining, suit for the CNC Lathe with high rigidity.
