Cause Analysis and Solution Ideas for Frequent Chipping and Breaking of the Milling Tool on the Face of the Cylinder Block Fuel Injector

Wu Ling

Abstract：Aiming at the problem of frequent chipping and breaking of the milling tool on the face of the cylinder injector， combined with the processing technology， the factors that may lead to the occurrence of the problem are analyzed， and finally three factors including the blank allowance， the tool processing path and the tool structure design are found. In view of the three influencing factors， reducing the machining allowance， changing the machining path， and expanding the tool chip flute and other measures， the problem of chipping and tool breakage has been solved.

Key words：chipping， tool structure design， chip flute， blank allowance， fuel injector
