目前多砂轮外圆磨床用于粗磨和精磨曲轴和分配轴的轴颈通常这种机床是以自动循环或半自动循环进行工作的。实践证明,用试磨的方法按给定的轴颈尺寸来调整多砂轮机床是非常困难的。此外,由于砂轮磨损不均匀,机床有热变形,中心架及自动测量仪需不断调整,因此造成轴颈的径向尺寸产生误差,为了对此误差进行补偿,需周期调整机床,因砂轮修整器可保证每个金则占作脉冲进给,故可单独改变任意砂轮的直径。实践证明,砂轮直径和轴颈直径之间的变化关系对于不同
At present, multi-wheel cylindrical grinder used for roughing and finishing crankshaft and distribution shaft journal usually this machine is in an automatic cycle or semi-automatic cycle work. Practice has proved that the use of trial grinding method according to the given journal size to adjust multi-wheel machine is very difficult. In addition, due to uneven wear of the grinding wheel, the machine has thermal deformation, the center frame and automatic measuring instrument needs to be constantly adjusted, resulting in journal radial dimension error, in order to compensate for this error, the need to periodically adjust the machine, due to wheel dresser Each gold can be guaranteed for the pulse feed, it can be an independent change in the diameter of any wheel. Practice has proved that the relationship between the wheel diameter and journal diameter changes for different
