Traditional CNC machine tools are generally used for cutting materials such as metals and plastics, so can these machine tools be used for the machining of industrial special ceramics? In response to this problem, our company did a market research. The survey found that many cnc ceramic machining enterprises on the market now use traditional CNC machine tools, but the most strongly reacted problem by many users is that the failure rate of the machine tool during use is relatively high, especially the comparison of the accuracy of the machine tool after a period of use. obvious. In fact, this is a common problem of traditional CNC machine tools. Since the development of such machine tools was not specifically used for the machining of materials such as ceramics, no special treatment was made in the structural design and protection performance of the machine tools.
Ceramic engraving and milling machine
We all know that the machining of special ceramics uses grinding instead of cutting, so the powder particles generated in the machining are very small, and it is easy to enter into precision components such as screw and guide rails with the operation of the machine tool. The hardness is very high, so the harm to the machine tool is self-evident.
Let’s take a look at the characteristics of ceramic CNC machine tools:
When it comes to ceramic special CNC machine tools, we must first consider its protection performance, the better the protection performance, the more suitable for machining ceramic parts. Secondly, it is necessary to see whether the rigidity of the machine tool is enough. The sufficient machine tool rigidity can ensure that the machine tool always maintains small machine tool vibration during operation, which is beneficial to prolong the service life and machining accuracy of the grinding head. In addition, let’s see if the rotation speed of the spindle is enough. Generally, a higher rotation speed is required when machining ceramic materials. According to different ceramic products, spindles with several rotation speeds such as 18000, 24000, and 36000 can be selected. At present, for the machining of structural ceramics, two speeds of 18000 or 24000 are mainly used, and for products such as mobile phone back covers, it is best to choose a spindle with a higher speed of 36000 rpm.
Through the above analysis, we have concluded that: traditional CNC machine tools can be used to process ceramics, but this method will be particularly harmful to the machine, so we recommend the selection of special CNC machine tools for ceramics.
Ceramic chip ceramic precision parts processing
Pay attention to the impact of the processing of ceramic precision parts to avoid damaging the ceramic parts in the pump. The removed parts should be handled with care. At the same time, care should be taken to avoid the roughness of the broken seal surface. The use temperature is lower than ℃ (engineering plastic impeller The operating temperature depends on the material and medium). The welding process of ceramic suction cup is silver welding. When drilling ceramic chuck materials, the diamond grinding wheel uses high-speed diamond abrasive particles to cut the material. Grinding and polishing certain collars in industrial production. Grinding alone does not meet the surface finish requirements of ceramic chucks, usually grinding and polishing. On the other hand, the ceramic chuck material has less toughness and greater brittleness, and its strength is easily affected by surface cracks. The rougher the processed surface, the sharper the temperature difference is less than ℃. Widely used in mining, smelting, petroleum, chemical industry, dyes and other industries. Recently, in the wet smelting industry, ultra-high molecular weight polymer pumps have poor high-temperature wear resistance, ceramic lined pumps are easy to crack and damage, and high wear-resistant metal alloy pumps are expensive.
