我们用车床铣三时、四时水泵轴的键槽,方法简单,不需改动机床部件。现介绍如下。铣削前,将立铣刀夹在车床卡盘上,水泵轴压装在方刀架横向方向上。可在轴下垫不同厚度的铁板以校正轴位高低,横向进刀可用手动或机动。工作时应注意以下几点。三爪卡盘中心跳动不得太大,否则铣出的槽将变宽。中心跳动超过0.03毫米时,可在爪上垫薄紫铜皮校正,或修理、更换卡盘。装压水泵轴时,轴心线应与车床主轴轴 We use the lathe milling three o’clock, four o’clock pump shaft keyway, the method is simple, without changing machine parts. Now introduced as follows. Milling before the end mill clip in the lathe chuck, pump shaft mounted on the square knife lateral direction. Under the shaft can be padded with different thickness of iron to correct the level of the shaft, the horizontal feed can be manual or motorized. Work should pay attention to the following points. Three-jaw chuck center beat not too large, or milling groove will be widened. Center beating more than 0.03 mm, can be clawed on a thin copper plate correction, or repair, replace the chuck. When loading the pump shaft, the axis should be connected to the spindle of the lathe
