RESEARCH abrading tool is a tool of the workpiece, is also the carrier of the abrasive

RESEARCH abrading tool is a tool of the workpiece, is also the carrier of the abrasive, hardness should be less than the hardness of the workpiece, has a certain wear resistance, commonly made ​​of gray cast iron. Wet lap metallurgical research  cup wheels  based ferrite; dry  tool & cutter  lap places of uniform and fine pearlitic matrix. Ground threads and small parts of complex shape, the commonly used mild steel lap. Grinding holes and soft metal material, mostly made ​​of brass, copper lap. Should have  centerless grinding  stiffness lap, the working surface to have a high geometric precision. Lap during the grinding process has also been cutting and wear, such as operating properly, its accuracy can be improved, so that the machining accuracy can be higher than the lap of the original accuracy.
