摘要
为解决 471型管端车丝机加工石油套管时管端螺纹锥度不规则变化的问题 ,对外圆加工刀具几何参数作了合理改进 ,从而减小了外圆加工时钢管所受径向切削力 。
To solve the problem of irregular variations of thread taper on the pipe end during machining oil casing pipes with 471 threading machine tool, the geometric parameters of cylindrical turning tools are improved rationally, so that the radial cutting force applied to the pipe end is reduced during turning outer circle, and the precision stability of thread taper on the pipe end can be guaranteed.
