What are the benefits of lapping compared to grinding ...

Where a grinding pad is used on a revolving platen, it will always wear unevenly due to the difference in relative movement speed and pad area across the pad diameter, this means that the grinding effect on the sample will change during the process, reducing the accuracy of the sample and the uniformity. Lapping is a more gentle process as the ...
