PCD cutting or milling tools are the most commonly used diamond materials in production. It is not only suitable for the field of general machining, but also widely used in 

automobiles, motorcycles, high-speed trains, petroleum, chemical, construction, wood processing and Aerospace and other industrial sectors. In the field of automobiles 

and motorcycles, PCD cutting tools are suitable for machining the skirt parts, pin holes, cylinder blocks, gearboxes, carburetor and other wear-resistant parts of aluminum alloy 

pistons for engines.

Most of these parts are aluminum-based composite materials with high silicon content (Si> 12%). The hard particles with high hardness (such as the hardness of SiC up to

3000 ~ 3500HV) are distributed in the aluminum alloy matrix, just like grinding wheels. The abrasive particles in the same will scrape and impact the cutting edge of the tool, 

and the cutting edge will quickly wear out. The higher the hardness of the hard particles, the larger the size of the particles, and the greater the number of particles, the faster 

the tool wears. Therefore, it is difficult to process with traditional cemented carbide tools, and the tool life is very low or cannot be used at all.

Diamond is the hardest substance known in the world, and actual use proves that it is the best tool material for processing aluminum matrix composite materials. LINKUT 

diamond tools have the advantages of extremely high hardness and wear resistance, low coefficient of friction, high elastic modulus, high thermal conductivity, low coefficient 

of thermal expansion, and low affinity with non-ferrous metals. Commonly, when machining the composite materials: delamination, burrs, curling is likely to occur, use of general

tools are prone to problems such as wear resistance, low efficiency, etc. The use of LINKUT diamond tools can effectively avoid the above problems, and the tool has good sharpness, 

high wear resistance and long life.
