一、前言国内汽车、内燃机行业为了缩小与工业发达国家间的差距,将发动机进行了改型换代。改型后的发动机对凸轮轴的制造精度,尤其对凸轮的形面精度均提出了较高的要求,由原来的形面允差±0.05～±0.08mm,提高到±0.015～±0.025mm,但是目前我国所生产的凸轮轴磨床是满足不了以上精度要求的。如何使凸轮轴磨床适应汽车、内燃机行业的发展,是我们磨床制造厂工程技术人员的当务之急,为此,对提高凸轮轴磨削形面精度进行了探讨。二、凸轮轴磨床的磨削特点
I. Preface The domestic automobile and internal combustion engine industries have transformed the engines in order to narrow the gap with the developed countries in the industry. Modified engine camshaft manufacturing precision, especially for the cam surface precision are put forward higher requirements, from the original surface tolerance ± 0.05 ~ ± 0.08mm, increased to ± 0.015 ~ ± 0.025mm, However, at present, China’s production of camshaft grinding machine can not meet the above accuracy requirements. How to adapt the camshaft grinding machine to the development of automobile and internal combustion engine industry is the most urgent task for the engineers and technicians of our grinder manufacturer. Therefore, the precision of improving the grinding profile of camshaft is discussed. Second, the grinding characteristics of camshaft grinding machine
