(一)高速车削螺丝方法的简单介绍 (1)过去车削螺丝时,生产效率低的 原因: 车工作业中,较难做的工序。就是车削各种形状的丝扣。主要是由于螺纹形状的尖削,夹角小,在切削时,刀刃须全部埋入工作物里,致使刀头部份散热不易,形成刀尖的局部高热。同时 切屑排出的条件很差,形成切屑 (A) a brief introduction to the method of high-speed turning screw (1) the reasons for the low productivity when turning the screw in the past: the car more difficult to do the job. Turning is the turning of various shapes. Mainly due to the thread shape taper, angle is small, in cutting, the blade must be fully embedded in the work, resulting in the blade part of the heat is not easy to form the tip of the local high fever. Chip discharge conditions at the same time poor, the formation of chip
