nose angle

When the involute worm is cut in the gear lathe SB6510,it is more influencing on the cutter turning angle that different helix angle worm is cut by a same gear lathe cutter adopting cutter turning angle method in production.

在SB6510车齿机上加工不同螺旋角的渐开线蜗杆,用同一种车齿刀采用刀具扳角的方法,对刀具的切削角度影响较大。

The bevel milling cutter for cutting groove of oil casing-pipes was designed.

设计了用于油气田管道坡口切割的角度铣刀。
