PCBN Hard Turning Inserts for Turning 20CrMnTi Gear Wheel Steel materials Gear with Halnn WNGA

1. Halnn Tools PCBN Hard Turning Inserts for Turning 20CrMnTi Gear Wheel Steel materials Gear

The advantages of CBN Inserts for Turning 20CrMnTi Gear Wheel Steel

1.Realize hard turning with good Machine rigidity: The premise of hard turning is good cnc lathe. In recently, most machine has good rigidity, can obey hard turning. So it will not affect hard turning. Halnn also have some cbn inserts grade which can be used for the machines with bad rigidity.

2.Dry cutting, reduce the environment pollution: cbn insert usually use dry cutting process, not only reduce the coolant device, but also save the coolant costs, and protect the environment.
