The grinding wheel spindle isdriven through a servo motor via synchronous belt drive, the grinding wheel spindle is supported through an angular contact ball ceramic bearing in triple fit, the XZ shaft is driven through the servomotor, a precise ball screw pair is adopted for transmission, a grating ruler is added, and a closed-loop detection system is formed; a positive pole of the power source is directly connected with aworkpiece tip, a negative pole is connected with the grinding wheel spindle through an electric brush, an ultrasonic transducer is in contact with a tail tip for mounting, ultrasonic waves sent out bythe ultrasonic transducer is transmitted to the workpiece through the tail tip, under the ultrasonic cavatition, grinding wheel sharpening is achieved, crack initiation and extension in an electrochemical reaction film can be promoted, the removal efficiency is improved, and through changing of parameters such as ultrasonic frequency, current, grinding wheel rotating speed and the like, the grinding process capable of improving the grinding efficiency and the quality of a material difficult to grind can be explored.

Description

technical field [0001] The invention relates to the field of grinding processing, in particular to a grinding device for processing refractory materials by means of ultrasonic and electrochemical compound grinding. Background technique [0002] Electrochemical grinding is a special processing technology that uses the principle of electrolysis to apply electrolysis to mechanical grinding. The grinding wheel is attached. During the grinding process, electrolysis is produced while supplying grinding fluid. Under the electrolysis and grinding of the grinding wheel, the electrolysis products are continuously removed, so as to achieve the purpose of grinding. Ultrasonic grinding is a processing technology that uses ultrasonic waves to force the grinding wheel or the workpiece to vibrate at a certain frequency during the grinding process. The mechanism of ultrasonic grinding is to force the abrasive suspension to hit and polish the surface to be processed at high speed by generat...
