Machining
Machining & Grinding
Grinding is the first process used for ceramic materials. Ceramic grinding refers to the surface processing of ceramics with abrasive afer forming ol
sintering. The method is to select large grain grinding wheel or electroplated diamond grinding wheel on the existing arinding machine for
conventional qrinding.
However, ceramics have the characteristics of high hardness and strong wear resistance, so diferent processing technologies are needed to treat diferent product recuirements. Dierent processing methods can be used when processing outer circle,inner hole, plane and thread. Generaly, the
minimum tolerance can reach +0.003mm.
Laser Machining
Laser processing ceramic technoloay is to use the hioh-eneroy densilv laser beam to act on the suace of ceramic materals to make them melt undel heat, so as to realize the processing of ceramic materials. it is mainly used to process ceramic parts or ceramic material surfaces with complex shapes and small dimensions.
Laser processing has various advantages, such as: fast processing speed; The timeliness and accuracy of processing are very high The machining
accuracy is hiah and can reach the micron level.
But at the same time, the equipment is complex and needs experienced operators to operate. This requires higher requirements for operators. Our
company is equipped with experienced operators who can process various ceramic parts according to customer requirements. For laser cuting, laser drilling, laser scribing and other processes can be completed.
Lapping & Polishing
Grinding and polishing is a kind of ultra-precision machining method. This method uses free abrasive to produce fine screening effect on the surface material to be processed, so as to achieve the processing effect.Iin the ultra-precision machining and finishing of ceramic materials, especially in the precision machining of ceramic balls for ceramic bearings, grinding and polishing play an irreplaceable role.
In order to further improve the surface accuracy after ceramic polishing, soft elastic or viscoelastic tools and micro-powder abrasives are used to
make the surace of the workpiece reach the miror-like finish. The mechanism of polishing is mechanical micro-removat the micro-cuing acion of
the front end of the abrasive removes the concave and convex suface. Through grinding and polishing, the product can achieve the mirror efect
PRODUCTION
Preparation Raw Materials
The powder is processed by physical and chemical methods to obtain the required specifications of powder; Then, according to the composition of the porcelain, various raw materials are weighed and batched, and then mixed to prepare different forms of billets according to different forming methods. Our company is equipped with special raw material processing equipment, such as ball mill, spray dryer, etc., which can control the material formula by itself.
Press Molding
Forming is to make the blank into a blank with a certain shape and specification. The slurry or powder can be made into semi-finished products with certain shapes and specifications by hot pressing, dry pressing or static pressing;
The available methods include: wet plastic molding, injection molding, molding, injection molding, hot die casting, isostatic pressure molding, plastic molding, belt molding, etc. The forming methods of industrial ceramics include dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and static pressing.
Kiln Sintering
Sintering is the process of heating the formed green body at a high temperature lower than the melting point. As the temperature rises, the powder inside the green body will bond. Through the process of material migration, it will lead to densification and high strength. During the process, the pores will be gradually eliminated, resulting in shrinkage, making the green body become a dense ceramic body with a certain strength.
Ceramic sintering methods: ordinary sintering, hot-press sintering, atmosphere sintering, hot-press sintering, etc.
Product Processing
After forming and sintering, industrial ceramics can also be processed with subsequent precision as required to meet the accuracy requirements of surface roughness, shape, size, etc., such as grinding, grinding and polishing, ultrasonic processing, laser processing, and even cutting processing.
