我厂的无心磨床垫刀片,有整体高速钢和键硬质合金垫刀片两种。在钻头、中心钻、丝锥和圆板牙等产品(包括其它圆柱形零件) 的加工中,使用比较普遍,所以,消耗量极大。垫刀片的结构虽然比较简单(图1)。但由于工艺性差,加工困难,次废率较高、材料利用率也低,因而 I plant centerless grinder blades, the overall high-speed steel and carbide key blade two. In the drill, center drill, tap and disc teeth and other products (including other cylindrical parts) processing, the use of more common, so consumption is extremely large. Pad blade structure is relatively simple (Figure 1). However, due to poor workmanship, processing difficulties, higher rates of waste, material utilization is also low, and therefore
