Alumina Ceramic mechanical vacuum arm robot


Alumina ceramics can be said to be a very high hardness material, that means the processing is very difficult. Alumina mechanical vacuum arm used in the semiconductor industry, mainly responsible for the transfer of wafers, the requirements for processing accuracy is better, the processing process is a difficult point in the industry, SHENZHEN HAORUI INDUSTRIAL ceramics is a professional engaged in ceramic processing manufacturers, summary and innovative research and development of a variety of processing techniques. Has solved the problem of chipping in the ceramic processing.We provide professional efficient,high-quality services,constantly innovate in technology and products.


First of all, the flatness of the alumina ceramic machine trimming, generally use the grinder to processing, grinding process notes: alumina ceramic precision machining of the most common machine tools are: milling machine, surface grinding machine, internal and external grinding machine, etc., today focuses on understanding the milling machine, surface grinding machine processing technology. Alumina ceramic processing front-end process is generally the use of surface grinding machine for processing, such as the use of grinding machine for opening, grinding datum, etc.. Usually the grinding process of the feed control in the 0.03 or so for the best, the use of diamond resin grinding wheel is more suitable. For the grit size of the grinding wheel, we can choose according to the required surface roughness, the general situation is recommended to choose between 150-400 mesh. Usually many of the materials of the back-end process or the need for engraving and milling machine processing, in fact, you can first use the grinder to process to a size closest to the finished product and then use the engraving and milling machine processing, on the one hand, can effectively reduce the processing of engraving and milling machine time-consuming, on the other hand, can greatly enhance the processing efficiency and reduce the cost of processing.

Secondly, the attention of the engraving and milling machine processing process: after the use of grinding machine processing, the next step is to enter the engraving and milling machine processing stage. The processing stage of the carving and milling machine points are more, if it is a little bit of inattention will cause the material to appear chipping or fracture phenomenon, so in the processing process must pay special attention. In fact, engraving and milling machine processing ceramic process is most likely to appear chipping phenomenon, especially in the process of beating through the ceramic body, this phenomenon is particularly obvious.
