涂层硬质合金刀片切削性能的试验研究

A Study on the Cutting Performanceof Coated Carbide Tools

为确定涂层硬质合金刀片的切削效果，对国产ＴｉＣ涂层与不涂层的硬质合金可转位式刀片在相同的切削条件下进行切削力、刀具磨损、摩擦系数等试验。试验结果表明ＴｉＣ涂层硬质合金刀片在提高切削性能方面效果是显著的，使切削力与摩擦系数降低１０％～１５％。

To make sure the cutting efficiency of the Chinesemade coated carbide tools, the wear resistance as well as cutting force,coefficient of friction of the adjustableposition cutting tools coated and uncoated inserts were tested in the same cutting conditions.The results showed that the coated one had remarkable advantages of extending tool life and improving cutting efficiency with frictional coefficient declining by 10% to 15%.
