Features of  Lapping Surface Plate:

Easy and quick in embeddingemery, which can ensure the surface is embedded with sufficient amount of emeryand can be easily embedded the same type emery powder after using and smoothfinish will be significant improved after further grinding.

Easy to achieve highdegree of finish and grinding property that required by gauge block.

The surface plate is featuredwith good and persistent machinability and has a long service life. 

Lapping finish is a precisionmachining process, in which a thin layer will be removed from the working surfaceof the cast iron plate by using grinding tools and abrasives. According to theprocess method, lapping method can be divided into wet lapping, dry lapping andsemi-dry lapping. Dry lapping, also know as embedded emery lapping, is thecommon used finishing method for cast iron surface plate.
