Ceramics are typical hard and brittle materials, with high hardness, wear resistance, in addition to easy to cut ceramics, such as general engineering ceramics cutting, super hard tool material (diamond) is the ideal choice for turning tools.
For rough processing of ceramics generally choose polycrystalline diamond tool, polycrystalline diamond (PCD) tool is artificial diamond particles sintered under high temperature and high pressure, encounter impact or vibration is not easy to damage, suitable for rough processing of ceramic materials.
For finishing ceramic materials, natural single crystal diamond tools are used for micro cutting (with small cutting depth and feed). Natural single crystal diamond cutting edge sharp, high hardness, wear resistance is 10 times of alumina ceramics, cutting thermal wear is very small, can ensure higher dimensional precision and surface finish of ceramic materials. At the same time, it is also used for other parts that grinding wheel is difficult to process, such as slotting machining, surface copying machining, etc.
CVD diamond coated milling cutter is also used for milling ceramics, which can achieve mirror effect. The specific advantages are as follows:
(1) High hardness, with good resistance to high temperature oxidation.
(2) Film/base bonding strength is high, under the action of large cutting force will not peel from the tool matrix, long service life.
(3) high thermal conductivity, low friction coefficient, high surface finish of the processed workpiece.
(4) Reduce the number of tool changes, improve the efficiency of the equipment, to meet the processing requirements of large quantities, high efficiency and high precision of the machining center.
