In recent decades, with the advancement of The Times and the development of science and technology such as (electronic technology, space technology, Internet technology, etc.), as well as the common development of basic theory and testing technology, ceramic materials research has made a qualitative leap in the original field. In order to meet the technical requirements of new ceramic materials, special ceramics which are very different from ordinary ceramics in raw materials and process or performance came into being.
Zirconia ceramic processing
Special ceramics are not yet very clear definition, generally speaking, it is generally believed that special ceramics are the use of ultra-high precision or synthetic raw materials, can accurately control the chemical composition, according to the easy to carry out the microstructure design and control of the production technology to process, and is a kind of ceramics with high performance. It has ultra-high strength, extremely high hardness, high elastic modulus, high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, thermal shock resistance and other characteristics. Functional ceramics refer to a class of ceramics with electrical, magnetic, optical, acoustic, superconducting, chemical, biological and other properties, and have the function of mutual conversion.
No matter what kind, it has the characteristics of high hardness, high brittleness and low fracture toughness in common with ceramic materials, which makes it easy to produce deformed layers, surface/subsurface micro-cracks, material powder, fuzzy surface, phase change area, residual stress and other defects in the processing of ceramic materials, which is the difficulty of processing special ceramic materials.
At present, the main method of cnc machining ceramic materials is to process ceramic materials with a grinding rod made of diamond gravel, which seems to be a two-sentence thing, but in fact, it is a very challenging processing method. As mentioned earlier, special ceramics have a high hardness, which is second only to diamond hardness. The hardest material in nature, it needs a very mature and stable processing technology, and now the development of industrialization is faster and faster, there are many manufacturers have already had the conditions for processing special ceramics, speaking of here I think you will think of Guangdong Province's most famous ceramic manufacturers, not only good processing quality, And the processing technology and precision processing equipment are relatively mature.
When it comes to equipment, it is best to process ceramic materials with a special ceramic CNC, this kind of machine tool can effectively process ceramics and other hard materials, the main performance is strong rigidity, good protection effect, can resist the ceramic powder produced in the process of ceramic processing erosion of the machine tool, while its rigidity can also support it for high-precision processing of ceramics.
