Automobile related parts processing cases I



1. Case of high efficiency processing of automotive transmission

pcd and pcbn cutting tools


The transmission housing is one of the most important parts of the car, assembling parts such as shafts, sets and gears to keep them in the right position altogether. Therefore, the assembly accuracy of these parts box components and the performance and life of the installed machine are largely determined by the processing quality of the box itself.


Transmission materials are often used for gray cast iron, can also be used cast steel parts. For cast iron transmission housing blank machining with slag and pores, traditional processing methods are difficult to meet the processing requirements of the transmission housing, More Super Hard introduced a multi-cutting edge PCBN blade (multi-tooth milling disc) for easy loading and unloading, a blade can be processed 70-100 pieces, After the edge is worn, another edge can be replaced, improving the processing efficiency by 50-70%.
