What processing methods are available for special industrial ceramic materials?
Special industrial ceramic material machining mainly includes turning processing, grinding processing, drilling processing, grinding and polishing, etc.. The next by the professional production of industrial ceramics manufacturers Mei Cheng ceramic manufacturers to highlight the special industrial ceramic materials have what processing methods.
(1) the ceramic material turning processing
Turning processing is mainly with diamond tools cutting high hardness, high wear resistance of ceramic materials. Polycrystalline diamond tools are difficult to produce smooth cutting edge, generally used only for roughing; fine turning of ceramic materials, the use of natural monocrystalline diamond tools, cutting with micro-cutting method. Because of the hardness and brittleness of ceramic materials, it is difficult to ensure the accuracy requirements of turning processing, so the application of turning processing is not much, basically still in the research stage.
(2) Grinding of ceramic materials
The grinding of ceramic materials is one of the most used processing methods. Grinding wheels used in the grinding process generally choose diamond grinding wheels. Different scholars have different explanations for the grinding mechanism of diamond wheels, but in general, one thing is common, that is, brittle fracture is the main reason for the formation of material removal. Grinding process, chip removal is a major problem, generally using cooling working fluid cleaning. The coolant not only plays the role of flushing the chip powder, but also reduces the temperature of the grinding area, improves the grinding quality and reduces the thermal decomposition of the binder around the grinding grain. The grinding fluid is generally used with good cleaning performance and low viscosity. Diamond grinding wheels have different grinding characteristics depending on the type of bond and the concentration of abrasive grains. The size of diamond particles is another major reason for the surface quality of ceramic workpieces. The larger the particles, the greater the surface roughness, but the higher the processing efficiency.
(3) Drilling of ceramic materials
Most of the ceramic materials are drilled with a hollowing drill. Hollow material drill structure for a ring-shaped diamond grinding wheel welded to a hollow steel pipe, welding process for silver welding. When drilling ceramic materials, diamond grinding wheel high-speed rotation, the use of the end face of the diamond grain cutting material.
(4) ceramic material drilling process
Ceramic material drilling more use hollowing drill. Hollow material drill structure for a ring-shaped diamond grinding wheel welded to a hollow steel pipe, welding process for silver welding. When drilling ceramic materials, the diamond grinding wheel rotates at high speed, and the diamond grains on the end face are used to cut the material.
