So they are widely used to machine difficult-to-cut materials such as engineering ceramics, optical glass and hard alloy.
With the proper heating time and energy density selected, the metal bonded of the wheel is softened, thus facilitating the removal of the bonding material.
This is conceptually similar to that of laser-assisted machining of advanced ceramics [2], where the removal mode of hard, brittle materials can be changed from brittle fracture to ductile flow removal, thereby improving the surface quality and reducing the wear of cutting tools.
Because some big diamond abrasives were pulled out from the bonding material, there are some voids left on the surface of diamond wheel.
