装有超硬材料(以下简称CTM)刀片的刀具耐磨,尺寸稳定性高。CTM问世后,即作为半精加工或精加工刀具用在车、铣、镗等金属切削机床上。加工光洁度可达▽_7—▽_8。为扩大CTM刀片的应用范围,苏联于1976年开始在3Г71型磨床上试验用CTM铣刀代替砂轮精铣铸铁零件,以后逐步用于生产。仅文献(1)中就提到有十几家工厂用此法加工。加工的对象主要是各种机床的床身、立柱、拖板及各种箱体零件的导轨面;使用的设备是导轨磨床和平面磨床。现把有关情况简述如下: 一、在磨床上以铣代磨,加工质量好、效
Tool equipped with super-hard material (hereinafter referred to as CTM) blade wear-resistant, high dimensional stability. After the advent of the CTM, that is used as a semi-finishing or finishing tool in the car, milling, boring and other metal cutting machine tools. Machining finish up to ▽ _7- ▽ _8. In order to expand the scope of application of CTM inserts, the Soviet Union started to test the use of a CTM milling cutter on the 3Г71-type grinding machine to finish the cast iron parts instead of the grinding wheel in 1976 and gradually put it into production. Only the literature (1) mentioned there are dozens of factories using this method of processing. The main processing object is a variety of machine bed, column, carriage and a variety of cabinet parts rail surface; the use of equipment is rail grinder and surface grinder. Now the situation is briefly described as follows: First, the grinder on behalf of the milling mill, processing quality, effectiveness
