Ceramic suction discs are mainly used in photovoltaic quartz boats, graphite boats and loading and unloading machines. At present, ceramic suction discs are still relatively popular. The demand is mainly in Jiangsu and Guangdong. What materials are ceramic suction discs made of? Woolen cloth?
Generally speaking, ceramic suction discs are made of alumina ceramics. Alumina ceramics are a special ceramic material. In the ceramic classification, they are special ceramics and belong to oxide ceramics. Their Rockwell hardness is HRA80-90. The hardness is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel. Its density is 3.5g/cm3, which is lighter than steel. It is light in weight, wear-resistant, and high-temperature resistant. The combination of various excellent properties makes it Alumina ceramics are very popular and have become the most widely used ceramic materials among oxide ceramics.

In most cases, ceramic suction discs are used as consumables and cannot be recycled. Generally, additives are added to alumina ceramics during production to increase toughness and make them less likely to deform, which can effectively increase the service life of ceramic suction discs. Greatly reduce costs.
Although ceramic suction discs are very useful if they are made of alumina ceramics, it is quite difficult to process. As mentioned earlier, the excellent characteristics of alumina ceramics, but some of them have become an obstacle to processing. In particular, the high hardness and wear resistance make the processing of ceramic suction discs even more difficult. There are several machine tools that can process alumina ceramic materials, but the best one is the ceramic-specific CNC. The spindle speed of this type of machine tool High, good protection, strong stability, very suitable for processing all kinds of ceramic materials. As long as you choose a grinding rod with diamond grit and set the processing process, the quality of the processed ceramic suction discs is very high. There is a Mingrui Ceramics in Dongguan , they use special CNC for processing ceramics, so their ceramic suction discs are of high quality. In addition to special CNC for ceramics, ordinary CNC and graphite CNC can also process alumina ceramics. If ordinary CNC is used to process alumina ceramics, the product quality will not be as high. Ordinary CNC The machine tool is suitable for processing metals, plastics and other materials, but it is a bit reluctant to use it to process hard materials such as ceramics.
Alumina ceramics can not only be used to make ceramic suction sheets, but also are used in the fields of machinery, electronics, chemical industry, medicine, construction, aerospace and other fields.
