摘要

在不同切削速度(200～230 m/min)和切削深度(0.5～2 mm)下试验研究了普通20CrMnTiH齿轮钢(0.006%S)和含硫20CrMnTiH齿轮钢(0.031%S)的切削性能。结果表明

随切削速度增大

刀具的磨损增大

在200 m/min

0.031%S钢是0.006%S钢刀具的使用寿命的2.8倍;在230 m/min

0.031%S钢是0.006%S钢刀具使用寿命的2.6倍;随切削深度增加

切削力增加

但在相同切削深度下

0.031%S钢的切削力低于普通0.006%S钢;由于0.031%S钢存在≤6μm的MnS夹杂

使切屑易断

并硫化物夹杂能够包裹Al

尖晶石夹杂

减少刀具磨损

提高钢材的切削性能。

Abstract

The cutting characteristics of common gear steel 20CrMnTiH (0. 006% S) and sulphur bearing gear steel 20CrMnTi (0. 031 % S) with different cutting speed (200 ~230 m/min) and cutting depth (0. 5 ~2 mm) have been tested and researched. Results show that with increasing cutting rate

the wear of tool increases

with cutting speed 200 m/min the service life of 0. 031% S steel is 2. 8 fold as long as that of 0. 006% S steel and with cutting speed 230 m/min the service life of 0. 031 % S steel is 2. 6 fold as long as that of 0. 006% S steel ； with increasing cutting depth the cutting force increases

but with definite cutting depth the cutting force of 0. 031 % S steel is lower than that of common 0. 006% S steel ； As there are ≤6 μm MnS inclusions in 0. 031 % S steel

the chips are easily broken

and the manganese sulphide is able to clad

spinel inclusions led to decrease of tool wear and increase of cutting characteristics of steel products.
