Clutch Compressing Disc is an important structure of clutch, which plays an important role in driving safety. LINKUT PCBN cutting  tool has high hardness and high wear resistance, 

in this turning process, with obvious advantages.

Advantages of LINKUT PCBN insert/cbn insert such as SNGN120412, WNGA080412 turning Clutch Compressing Disc:

1) High Impact Resistance;  2) High hardness, good wear resistance and high temperature resistance;

3) High precision, good consistency; 4) Suitable for high speed cutting  5) Indexable multi edge cutting tools.

Difficulties in cutting Clutch Compressing Disc:

1) The defects such as hard spots, air holes, skin chilling layer and sand inclusion often appear on the blank of cast iron clutch pressure plate. The conventional cutting tools are easy 

to crack and have poor impact resistance.

2) The blank material of clutch compressing disc is generally HT250 cast iron, and the hardness is generally HB 180-220. The conventional cutting tool is easy to appear the 

phenomenon of non wear resistance, which affects the production efficiency.

3) The Clutch Compressing Disc has high requirements on the precision and surface finish after processing. The surface finish of cemented carbide insert can not be achieved, and 

frequent tool change also reduces the processing efficiency.

4) The selection of tunring tools is one of the important processes in the process of Clutch Compressing Disc processing, which not only affects the processing efficiency of the machine 

tool, but also affects the processing quality, which requires the selection of appropriate processing tools and the optimization of tool parameters.
