空气压缩机阀片,直径与厚度比值大,一般D/t>40,呈圆环形。零件较薄(一般为3毫米),光洁度(?)8～(?)9,翘曲度要求不大于0.04毫米(图1)。此类零件,在专业化的空气压缩机厂是采用专用磨床进行磨削的。在维修工作中,如果在普通平面磨床上用磁吸法磨削,很难加工出合格零件。对此,我们在普通平面磨床上采用无磁吸磨削法解决了这个难题。简介如下: Air compressor valve, the diameter and thickness ratio, the general D / t> 40, was a circular ring. Parts thinner (usually 3 mm), finish (?) 8 ~ (?) 9, warpage requirements of not more than 0.04 mm (Figure 1). Such parts, in a specialized air compressor factory is a dedicated grinding machine for grinding. In the maintenance work, if the ordinary surface grinder with magnetic grinding method, it is difficult to process qualified parts. In this regard, we use the ordinary surface grinder on the use of non-magnetic grinding method to solve this problem. Brief introduction is as follows:
