Because of the high demand on the surface finish quality of processed materials, generally, the grinding tool is prepared with abrasive of micron scale.
There are lots of ways to add or produce pores into materials.
What’s more, two fatal elements must be taken into account in the preparation technology of porous materials with pore-forming agents adding.
Due to the low refractoriness, the sintering temperature was not high enough, and then pore-forming materials could not completely react.

When these hard and brittle materials are used for mechanical structural parts, the need to cut or drill them is inevitable.
Currently, the methods of drilling hard and brittle materials include grain machining, which is a mechanical method, electronic beam machining, which is an electrical method, and laser machining, which is an optical method [4].
Among these, the grain machining has been widely used because of fewer restrictions in the materials and cost efficiency in facilities.
So brazed diamond tools are taken as the best one to machine hard and brittle materials.
