在普通车床上,利用尾座进行钻孔,如果操作工人不管车床的功率、结构能否满足生产工艺要求,想钻多大的孔,就钻多大的孔.这样做的结果.对车床很不利:一方面,当钻孔的切削扭矩过大时.钻头便在车床尾座套筒的锥孔中打滑,将锥孔表面严重研
In the ordinary lathe, the use of tailstock drilling, if the operator no matter the power of the lathe, the structure can meet the requirements of the production process, want to drill much holes, how much holes on the drilling. The result is very disadvantageous to the lathe: On the one hand, when the drilling cutting torque is too large, the bit slipping in the taper hole of the lathe tailstock sleeve, the cone surface serious research
