金刚石涂层刀具微细铣削硬质合金的试验研究

Experimental Research on Micro Milling of Cemented Carbide Diamond Coated Tool

硬质合金由于其优良性能被应用于精密模具和耐磨、耐腐蚀零件,是典型的难加工材料。CBN、金刚石等超硬刀具的出现,使得直接切削加工硬质合金成为可能。本文采用金刚石涂层刀具进行微细铣削硬质合金的试验研究,分析了加工过程中的切削力、表面质量以及刀具磨损。

Because of its excellent performance,cemented carbide is used to manufacture precision mould,wear-corrosion resistance parts. Cemented carbide is also a kind of typical difficult-to-machine material. The appearance of ultra-hard tool,such as CBN and diamond,makes it possible to cut cemented carbide directly. According to an experimental research on micro milling of cemented carbide with diamond coated tool. The cutting force,surface quality and tool wear during micro milling are analyzed.
