Ultrasonic assistant ELID end face grinding machine

Abstract

The invention discloses an ultrasonic assistant ELID end face grinding machine. The ultrasonic assistant ELID end face grinding machine comprises a machine bed, a metal bonding agent ultrasonic grinding disk, grinding fluid spray nozzles, carrying disks and ELID electrolysis electrodes. Each ELID electrolysis electrode comprises an electrolysis electrode power supply, a motor, a guide rail and anelectrode plate, wherein the electrode plate is arranged between the two adjacent carrying disks and mounted on the guide rail controlled by the motor; the distance between the bottom of the electrodeplate and the metal bonding agent ultrasonic grinding disk is controlled through the motor; the positive pole of the electrolysis electrode power supply is connected with the metal bonding agent ultrasonic grinding disk and serves as an anode, and the negative pole of the electrolysis electrode power supply is connected with the electrode plate and serves as a cathode. The electrolysis speed of the metal bonding agent ultrasonic grinding disk is controlled by adjusting voltage and current of the electrolysis electrode power supplies. The ultrasonic assistant ELID end face grinding machine hasthe following advantages that the ultrasonic vibration assistant grinding technology and the ELID assistant grinding technology are combined together, the metal bonding agent ultrasonic grinding diskis kept in a good state all the time, and the machining efficiency and machining precision of parts can be improved greatly.

Description

technical field [0001] The invention relates to the field of processing hard and brittle materials, in particular to an ultrasonic-assisted ELID (on-line electrolytic dressing grinding wheel) end face grinding machine tool. Background technique [0002] Due to their excellent mechanical properties, dielectric properties and chemical stability, hard, brittle and difficult-to-machine materials such as optical glass, artificial crystals, and ceramics are widely used in aerospace, national defense, automotive, information, machining and other fields. However, these materials have high hardness, high brittleness, and difficult processing, so it is very challenging to realize efficient and precise processing of them. As a commonly used precision machining method, grinding is often used for precision machining of hard and brittle materials. In the grinding process, the processing efficiency and processing accuracy are contradictory. In order to improve the grinding efficiency, it ...
