缓进给成形磨削工艺是一项先进的金属加工技术,国外早在六十年代就在生产中应用,七十年代取得很大进展。近年来,随着计算机技术的进步,工艺更趋成熟。我国从七十年代中期开始研制,但由于种种原因,未能形成批量生产能力,每年需花费大量外汇从国外进口。1988年北北中国机床工具博览会展出了杭州机床厂生产的HZ—037缓进给成形磨床。该磨床成功地进行了多种磨削试验,如游标卡尺尺框槽尺身一次成形磨削,槽底平行度为0.01毫米,游标卡尺尺框槽、外形、尺身正反面槽等一次磨去量2～4毫米;又如锯片铣刀齿形成形磨削时,砂轮按齿形要求修整,几十片铣刀叠合一起加工。
Slow into the shape grinding process is an advanced metal processing technology, foreign countries as early as the sixties in the production of applications, made great progress in the seventies. In recent years, with the progress of computer technology, technology is more mature. Since the mid-1970s, China started to develop it. However, due to various reasons, it failed to form a mass-production capacity and needed to import a large amount of foreign exchange each year from abroad. 1988 North and South China Machine Tool Expo exhibited at the Hangzhou Machine Tool Plant HZ-037 slow into the forming grinder. The grinder successfully carried out a variety of grinding tests, such as a vernier caliper ruler frame forming a groove grinding, groove bottom parallelism of 0.01 mm, vernier caliper ruler groove, profile, ~ 4 mm; Another example is the saw blade cutter tooth shape grinding, the grinding wheel according to the tooth shape requirements, dozens of milling cutter overlap together processing.
