1.Machining
 
¡¡¡¡Machining of ceramic materials is the traditional processing techniques, is the most extensive application process. Mainly refers to machining of ceramic materials for turning, cutting, grinding, drilling, etc.. The process simple, efficient processing, but because of the high-hard ceramic materials, high-brittle, so it is difficult machining processing complex shape, size, high precision, low surface roughness, high reliability, the engineering ceramic parts. The picture shows the next cutting, grinding, drilling diagram.

(1) machining of ceramic materials
 
¡¡¡¡Cutting is the use of diamond, cubic boron nitride, carbide cutting tools, such as super-hard ceramic materials for the plane processing, wet cutting is usually used, that is constantly cutting fluid jet to the cutting tool. The use of cutting fluid is the main purpose of cutting away debris, cutting tools and materials to reduce friction, reduce material and processing tool temperature, extended tool life and reduce material surface damage. As a result of processing, materials subject to mechanical stress the role of the surface, easily pit the surface of the material, collapsing the mouth of the lower surface and form micro-cracks. Tools, the choice of cutting fluid, cutting tool feed rate, feed rate optimization of process parameters, such as is the machining of ceramic materials research hot spots.

(2) ceramics grinding, polishing process

¡¡¡¡Sintered ceramic surface, as in the molding and sintering, as well as food processing a large number of dents, defects such as micro-cracks in the engineering and mechanical properties of the use is usually required before the test, after grinding, grinding and polishing processing. Processing them through the mechanism of abrasive workpiece and ceramics under a certain pressure, with the abrasive surface and the mutual movement, abrasive particles and the surface friction between convex peak in order to achieve the formation of the surface material. Abrasive, grinding fluid of choice, the role of pressure and sliding speed control is the crucial point of the processing methods.

2. EDM

¡¡¡¡1947 BRLazarenko EDM, such as a hard metal material new ideas. The late 80's, the introduction of EDM technology is the field of ceramics processing. Study shows that: when the single-phase or ceramic / ceramic, ceramic / metal composite material is less than the resistance 100¦¸.m, the ceramic material can discharge processing, processing principle slightly.

¡¡¡¡According to the basic principles of electrical discharge machining, materials depends mainly on the electrical properties of machinable, thermal physical properties, such as: electrical conductivity, melting point, specific heat, thermal conductivity and so on.

¡¡¡¡EDM is the preparation of high-dimensional accuracy, low surface roughness, high-performance ceramic components of complex shape promising processing technology, in-depth study steps EDM process control, design and preparation of conductive properties and superior mechanical properties of composite ceramic materials The method is crucial for future development.
