通过控制研磨参数，使得磨具磨损均匀，从而保证磨具面形精度。
This method is to control lapping parameters, make lapping tool wear well distributedly and thus assures lapping tool surface accuracy.
且磨损均匀，满足了工作寿命的相关要求，为电磁制动器安全制动、延长工作寿命提供了保证。
The attrition is even to satisfy the requirement of its working life, which provides the electromagnetic brake with better security and longer working life.
生产实际应用表明，新设计的辊型不仅明显降低了板凸度，同时使轧辊磨损均匀，辊耗量大大下降。
The practical application indicates that the new design not only reduces the convexity of the roll profile obviously, but also leads to homogeneous attrition of rolls and low rol...
