PCD tools for guide tube and seat bottom hole

The machining accuracy of valve seat and guide hole directly affects the engine power and exhaust emission indicators. Zhengzuan provides a series of precision composite machining tools that can easily realize the pre and post pressing of valve seat and guide hole. It can solve the problems of repeated tool adjustment, rapid wear and deformation, and low processing efficiency. At the same time, it can accurately ensure the matching clearance between the valve and the seat ring, and ensure the valve heating and sealing performance.

Scope of application: Finish machining before ring pressing.

Application: Automotive Industry - Cylinder head.
