For example, in the case of machining hard-brittle materials, compared with traditional grain tools, diamond tools have displayed unique superiority in machining quality, efficiency and tool life.
Consequently a new technology to radically improve the combining strength between bonded materials and grains is thirsted for a qualitative rush in the machining performance of diamond tools.
The machining objects are such hard-to-machining materials with high brittleness and high roughness as stone, ceramics and armoring compound board.

Fly ash: as cementitious materials, fly ash can improve the workability (fluidity) of the grout, playing a role of package the particle of sand and each component, fly ash occur chemical reaction with Ca(OH)2 or other alkaline earth metal hydroxide materials to produce a cementitious compounds with the properties of hydraulicity, which can strengthen the strength and durability of the material.
By testing different materials, the material requirements for the grout were determined and showed in Table1.

Diamond coating materials has higher hardness, better wear resistance and lower friction coefficient.
Because the CFRP is hard and brittle materials, broken chip is formed when it is cut.
