以铣代磨在冲击试样加工中的应用

Application of Milling Instead of Grinding in Impact Specimens Machining

介绍了笔者单位在冲击试样加工中应用基于高速切削加工技术的以铣代磨加工技术，代替了传统工艺中平面磨床的功能，改变了传统的冲击试样加工工艺。与磨削相比，以铣代磨切削力小，切削热影响小，刀具、试样变形小，实现了高精度、低粗糙度加工；同时单位时间材料切除率是磨床磨削的3～6倍，极大的提高了冲击试样的加工效率。

It was introduced that the process technology with milling instead of grinding based on high speed cutting had been applied in impact specimen process in Jigang Group Co. , Limited. The process technology had replaced traditional surface grinder processing and changed traditional impact specimen processing. Compared with the grinding, the cutting resistance on milling instead of grinding was weak; the influence of the cutting heat was little; the deformation of cutting tools and specimens was slight; it could be achieved high accuracy and low roughness processing, and the material removal rate per unit time was three to six times as the grinding rate of grinder, which could greatly improve the processing efficiency of impact specimens.
