磨削小孔比较理想的是采用金刚石砂轮,目前使用的金刚石砂轮有两种。1.电镀的:将金刚石粉末直接用电镀法喷镀在砂轮接头上使用(图1)。2.用酚醛树脂压制成型的:金刚石粉末用酚醛树脂作粘结剂,压成砂轮的形状(图2)然后焊在砂轮接头上使用。对于磨削小孔来说,用得比较多的是用电镀法制造的。不管用那一种方法制造的 Grinding holes is more ideal is the use of diamond grinding wheel, there are two currently used diamond grinding wheel. 1. Electroplating: The diamond powder is plated directly on the wheel fitting (Figure 1). 2. With phenolic resin molding: Diamond powder with phenolic resin as a binder, pressed into the shape of the wheel (Figure 2) and then welded to the wheel fitting. For grinding holes, the more used is made by electroplating method. No matter what kind of method of manufacturing
