薄壁复材零件的啄插式加工

Pecking and Inserting Machining of Thin-walled Composite Parts

环氧玻璃布层压棒是一种非金属复合材料,在铣削加工时其切屑为粉末状,切削过程中切削温度较高,并且环氧玻璃布棒是不良导热体,导热系数小,在加工过程中,排屑很困难,零件易发生开裂,导电性能极差无法进行电加工。以环氧玻璃布棒为材料的薄壁零件为例,由于其无法进行电加工,由机械加工完成清角工作,现通过改进原有的加工工艺,大幅度提高了产品合格率。

The laminated bar of epoxy glass cloth is a kind of non-metallic composite material.During milling,its chip is powder,the cutting temperature is high during cutting,and the epoxy glass cloth bar is a bad heat conduction body,and the thermal conductivity is small.In the process of processing,chip removal is very difficult,parts are easy to crack,and the electrical conductivity is extremely poor.Taking the thin-walled parts of epoxy glass cloth as an example,because it can not be processed by electricity,the angle cleaning work is completed by mechanical processing.Now,the qualified rate of the products is greatly improved by improving the original processing technology.
