Abstract: SiC ceramic is a new structural ceramic material with excellent high temperature mechanical properties. It has high temperature strength, strong oxidation resistance, good wear resistance, good thermal stability, small thermal expansion coefficient and high thermal conductivity. It has excellent properties such as high hardness and resistance to thermal shock and chemical corrosion. It has been widely used in petroleum, chemical, automotive, mechanical and aerospace industries, and has attracted more and more attention. However, due to the high hardness, brittleness and good wear resistance of the ceramic material, the processing is difficult and the processing cost is high. In the total cost of ceramic components, processing costs account for 30% to 60%, for many precision components, even up to 90% of the total cost, and a slight improper processing method will cause damage to the surface layer of the workpiece, in order to achieve ceramic materials Ultrasonic vibration is introduced into the processing of ceramic materials with high precision, high efficiency and high reliability. Extensive research at home and abroad has confirmed that ultrasonic vibration processing has significant advantages in improving material removal rate, improving workpiece surface quality, reducing cutting force and reducing surface damage of workpieces. In this paper, the side grinding experiment of SiC ceramics with or without ultrasonic vibration is carried out to compare the grinding force and the surface roughness of the workpiece during processing. The advantages of rotating ultrasonic vibration grinding and the surface morphology of the vibration are analyzed. Impact. The above text is selected from the "Research on Rotating Ultrasonic Vibration Grinding of SiC Ceramics", which is included in the "2012 China Superhard Materials Technology Development Forum Proceedings".
