高速精车铜套内孔车刀如图示。其特点为: (1)刃倾角为4°～5°,使切屑流向待加工表面(即走刀方向), 不划伤已加工表面,提高了表面光洁度; (2)在刀刃上有宽4～5毫米长的修光刃,因此,可以大走刀切削,并且加工表面光洁度可达▽6。 (3)刀具静止前角为-2°～-3°, 后角为-2°～-3°,小后角的宽度为0.5～1毫米。因采用装配式机械夹固,故可以根据詖加工工 High-speed finishing copper sleeve tool hole as shown. Its features are: (1) cutting edge angle of 4 ° ~ 5 °, the chip flow to be machined surface (ie, the direction of the knife), does not scratch the surface has been machined to improve the surface finish; (2) ~ 5 mm long wiper, therefore, it can be big cutting, and the machining surface finish up to ▽ 6. (3) The tool is still anterior horn -2 ° ~ -3 °, posterior horn -2 ° ~ -3 °, a small angle of 0.5 to 1 mm wide. Due to the use of fabricated mechanical clamping, it can be processed according to 詖
