Abstract

The invention relates to a dressing method and device for a resin-bonded superhard abrasive conductive forming grinding wheel, wherein the resin-bonded superhard abrasive conductive grinding wheel acts as an anode and is connected to a positive electrode of a DC power supply through a grinding machine spindle and an anode brush; The positive terminal of the digital multimeter is connected; the negative terminal of the digital multimeter is connected to the negative terminal of the DC power supply; the electrolyte is sprayed between the cathode and anode through the electrolyte outlet of the cathode component; the rotation speed of the shaping and dressing wheel is controlled by the movement of the dressing wheel spindle with the feed. The circuit is turned on, and the grinding wheel is used as the anode. There is a gap of 0.2mm to 0.5mm between the contour envelope and the working surface of the cathode component. The gap is filled with electrolyte, and the conductive abrasive on the surface of the grinding wheel is coated with metal. Electrolysis occurs; it is confirmed that the total current obtained by monitoring is kept constant for a certain period of time, and the circuit is disconnected; the mechanical action of the forming dressing wheel is used to remove the abrasive particles and the resin bond around them. The present invention can improve the dressing efficiency and dressing precision of the resin-bonded superhard abrasive conductive forming grinding wheel.

Description

technical field [0001] The invention relates to the technical field of machining of mechanical parts, in particular to a high-efficiency and precise dressing technology of a resin-bonded superhard abrasive conductive forming grinding wheel. Background technique [0002] The superabrasive grinding wheel has the advantages of sharp grinding edge, high abrasive hardness, good wear resistance, good precision retention and long service life, and has been widely used in the field of precision and ultra-precision manufacturing, and has been successfully promoted. The rapid development of grinding technology. However, in actual production, the excellent cutting performance of superabrasive grinding wheels has not been fully exerted, because its high hardness makes dressing very difficult, and it is difficult to achieve satisfactory shape accuracy and surface morphology after dressing. The key to grinding is dressing. The cutting performance of the grinding wheel during the grinding...
