Process Improvement of Camshaft of Heavy Duty Diesel Engine

Abstract

Camshaft is a key part of heavy duty diesel engine. The conventional process applies the profiling modeling grinders and universal milling machines to manufacture the cam. The weaknesses of this process include unstable cam profilogram, low accuracy, low flexibility, long product cycle and undesirable adaptability. M40 turn-milling centre and CN320 cam grinder are applied to upgrade the process. Compared with the conventional process, the improved process has evident advantages such as higher machining accuracy, surface quality and efficiency. And the compatibility with diverse product category was greatly promoted.
