在中等职业学校的普通车床竞赛训练与实习时,加工外圆锥时,由于车床小滑板存在间隙而难以保证角度精度,所以,探索出一种新方法以提高其精度:根据其加工特点和百分表的工作原理,用实际经验以及计算与测量的数据加以修正间隙,得到正确的角度,从而符合图纸要求;也可以运用这些容易掌握的方法和简单的计算,尽可能减少机床的间隙。 In the secondary vocational school training and training of ordinary lathe, machining outer cone, due to the existence of small lathe skid gap and difficult to ensure the accuracy of angle, therefore, to explore a new method to improve its accuracy: According to its processing characteristics and percentage The working principle of the watch, with actual experience and calculated and measured data to correct the gap, get the correct angle, so as to meet the requirements of the drawings; also can use these easy to master methods and simple calculations, as much as possible to reduce machine tool clearance.
