一般在加工大型零件时,常常会遇到需要刮平用来紧固螺帽的鱼眼窝式的凹凸台面(图1)。这些平面,一般都是将高速钢刀头装在镗床或钻床的刀杆上进行刮削。但是,所加工的零件材料,一般多为铸铁或铸钢制成。因此,在加工过程中,经常遇到夹砂和硬皮,使刀具易坏,而劳动生产率也不高。 Often in the processing of large parts, often encounter the need to scrape the nut used to tighten the nut nest-type concave and convex countertops (Figure 1). These planes are generally high-speed steel cutter head mounted on the boring machine or drilling machine tool sharpener. However, the processing of parts materials, mostly cast iron or cast steel. Therefore, in the process of processing, often encountered sand and crust, making the tool easy to damage, and labor productivity is not high.
