我厂生产的齿轮滚刀,它的主要工序——铲磨齿形、齿顶都是在K96铲床上进行的。但受机床精度所限,而不能提高加工质量。后来,在整顿产品质量当中,由于在K96铲床上安装了齿距误差补偿装置,使机床由原来只能加工B级精度,而提高到加工A级和 I gear hob factory production, its main processes - shovel tooth-shaped, addendum are on the K96 shovel bed. But limited by the accuracy of the machine, but can not improve the processing quality. Later, in the reorganization of product quality, due to the K96 shovel bed installed on the pitch error compensation device, the original machine can only be processed from the B-level accuracy, and raised to the processing level A and
