Description

technical field [0001] The invention relates to a constant-pressure ultrasonic-assisted fixed-abrasive cylindrical grinding device attached to a common lathe, which can realize high-speed and high-efficiency finishing of the cylindrical surface of hard and brittle ceramic materials. Background technique [0002] As a very important processing method in ultra-precision machining, ultra-precision grinding technology still plays an irreplaceable role in the precision machining of hard and brittle materials such as engineering ceramics. At present, domestic and foreign grinding processes mainly use loose grain abrasives on slow grinding machines, which have disadvantages such as low processing efficiency, high processing cost, unstable processing accuracy and processing quality, which makes traditional grinding applications subject to certain restrictions. Therefore, there is an urgent need for a new grinding technology that can not only ensure the grinding precision and process...

Problems solved by technology

Many scholars at home and abroad have studied the grinding technology of engineering ceramics, and proposed some new grinding processing technologies, such as magnetic grinding, elastic emission processing grinding, mechanochemical grinding, electrolytic grinding, etc., but these grinding methods are mainly to improve the grinding quality and Machining accuracy, most of them fail to effectively improve processing efficiency, especially in reducing processing costs, and still cannot change the impression of high precision, low efficiency, and high cost in people's minds of traditional grinding
