Diamond Precision Cutting Tools high efficiency machining of high hardness Ceramic Materials

Diamond grinding wheel is generally used to grind ceramic materials, but the production efficiency is low. If PCD tools are used for precision cutting, the production efficiency can be 

significantly improved and the production cost can be reduced.

Ceramics are typical hard and brittle materials with high hardness and wear resistance. In addition to easy cutting ceramics, such as general engineering ceramics, only superhard tool 

materials (diamond) can be competent.

1) Diamond Turning of ceramics

Rough machining: polycrystalline diamond (PCD) tool is generally selected for the rough machining process of ceramics. Polycrystalline diamond (PCD) tool is sintered by artificial 

diamond particles under high temperature and high pressure. It is not easy to be damaged in case of impact or vibration, which is suitable for the rough machining of ceramic materials.

Finishing: for the finishing of ceramic materials, Micro cutting with natural single crystal diamond tool (small cutting depth and feed rate are adopted). The natural single crystal diamond 

tool has sharp cutting edge, high hardness and wear resistance 10 times that of alumina ceramics. The thermal wear during cutting is very small, which can ensure the high dimensional 

accuracy and surface finish of ceramic materials. At the same time, it is also used for other parts that are difficult to be machined by sand wheel, such as slotting, curved surface profiling, 

etc.

2) PCD Milling of ceramics

Good machining surface quality plays an important role in reducing surface defects, improving part strength and equipment accuracy, reducing friction and wear, and prolonging the 

service life of ceramic parts. At this time, superhard milling cutter has become the choice for milling ceramic parts. LINKUT superhard milling cutter can process ceramic parts on 

CNC machine toolsremove most of the allowance, and then grind and polish, so as to realize the substitution of milling for grinding of ceramic materials, and the efficiency can be 

doubled.

Among them, the surface roughness of ceramic materials is affected by milling parameters, milling distance and other factors. Among them, the surface roughness increases with 

the increase of feed per tooth. Therefore, a small feed should be selected in the milling process.
