一、问题的提出众所周知,卧式镗床后立柱刀杆支架是在镗削箱体、车轮法兰、电机壳子等零件的后端孔或止口时起支撑刀杆的怍用。加工中刀杆虽有支撑但有时因其细长发颤就要限制切削的速度;因零件工位测量时刀杆还在工件孔中,这样就给工位测量带来了困难。为此,我们对其进行了改装。 First, the problem is well-known, horizontal boring machine after the column holder is in the boring box, wheel flange, motor shell and other parts of the back hole or the end of the support knife bar used. Although the arbor is supported in the machining, it sometimes needs to limit the speed of cutting because of its slenderness and trembling. The arbor is still in the hole of the workpiece during the measurement of the part position, which makes it difficult to measure the work station. For this reason, we modified it.
