Case of efficient machining of workpiece

Case of efficient machining of workpiece

1. Case -- efficient processing of automotive brake discs

In the past, the processing of automotive brake discs commonly used coated carbide blades, ceramic blades, although can complete the processing tasks, the time and production cost is high, and abrasive resistance is not good.

“More Super Hard” indexable CBN inserts SCGN090412, with ultra-high wear resistance and impact resistance, can effectively help customers reduce tool changing and production cost, improve processing efficiency.

2. Case -- Efficient processing of gear

There are two different main processing for automobile transmission gear, one is soft gear surface, the other one is hard gear surface. For soft gear surface, it is rolling → shaving → heat treatment. For hard gear surface, it is rolling → heat treatment (Carburizing) → Grinding.

In modern times, in order to meet customers high requirements (high efficiency, high precision and high stability) of automobile transmission gear, More Super Hard introduces sintered PCBN inserts which is successfully used in interrupted cutting for hard gear surface (HRC 62) of large gear, improves working efficiency a lot. What’s more, More Super Hard has made a new breakthrough in finishing of automobile gear, also hard turning and grooving of gear shaft.

3. Case--screw rod processing
