Description

technical field [0001] The invention belongs to the technical field of high-efficiency mirror grinding of hard and brittle materials, and in particular relates to an on-line dressing and shape detection device of a grinding wheel for ultrasonic electrolytic composite grinding of inner circles. Background technique [0002] The high-efficiency processing technology of mirror surface of hard and brittle materials is an important branch of ultra-precision processing technology, which is of great significance to the development of cutting-edge science and technology such as aerospace, national defense, information, microelectronics and optoelectronics. [0003] Due to the high hardness and good wear resistance of superabrasives, they are very suitable for efficient grinding of hard and brittle materials. However, the heat resistance of the resin bond is poor. At high temperatures, the bonding strength between the bond and the abrasive is low, and the high-efficiency cutting perf...

Problems solved by technology

The disadvantages are that the grinding wheel is easy to block, the processing efficiency is low, the cost is high, and the non-conductive oxide peeled off on the diamond grinding wheel is easy to scratch the workpiece. High efficiency and other issues have always been the main issues of research in this field, and have also become the bottleneck for further improvement of ELID grinding technology.

[0005] Ultrasonic vibration precision grinding is a processing technology that combines ultrasonic vibration with ordinary grinding. The main advantage recognized in precision machining is that it can obtain precise ultra-precision surfaces while being efficient, but the disadvantage is to ensure the stability of the vibration of the acoustic system. The difficulty of performance, the grinding wheel cannot be trimmed on-line, and the nano-surface with extremely low roughness value (less than 10nm surface) cannot be obtained efficiently, such as the surface of ELID mirror grinding, etc. These problems also restrict the wide application of this technology in high-tech fields. main factors of application
