Tappet hole rough machining compound reamer

For typical holes such as tappet hole, spark plug hole and fuel injection nozzle hole, how to improve the machining efficiency and ensure the coaxiality of each hole, Zhengzuan adopts multi process composite tools to process multi-step holes in a centralized manner, desalinate the boundaries of different machining processes, reduce the number of tool changes, save the tool change time, and reduce the tool inventory at the same time.

Coupled with the high precision and wear resistance of PCD, it perfectly solves the processing problems of difficult holes from process optimization to efficient and stable processing.

【Product features】

▪ Perfect heat shrink fit between cemented carbide bit and PCD reamer;

▪ The 0.003mm runout of the cutting edge ensures longer tool life and machining accuracy;

▪ Drilling and reaming integrated structure provides accurate guidance for reaming while drilling;

▪ The original sheet changing technology, the reaming accuracy is consistent with that of the new tool, and the cost is reduced more economically.
