Electrolytic dressing method of diamond cup grinding wheel

Principle of electrolytic dressing dressing electrolysis method is mainly used for metal bond diamond cbn grinding wheel, while electrolytic dressing, metal bonded grinding wheel with a DC power supply as a positive phase electrolysis anode electrode and the DC power tool as a negative phase electrolysis cathode, between the anode and the cathode having a grinding liquid is injected into the electrolysis of the electrolytic solution as, the diamond grinding wheel, the electrolyte, the tool electrode and the power supply circuit constituting the electrolysis, dressing, so that the electrolyte filled gap between the cathode and the anode, current from flowing through the electrolyte dressing grinding wheel, the surface of the metal component metal bond diamond Plastic Base Grinding Wheel under the action of electrolytic solution agent, dissolved in the electrolyte, and the electrolyte compound hydroxide ions generated by the flow of fine solids electrolyte away, greatly reducing the diamond grinding wheel surface bond strength, this time to use mechanical trimming method, trimming performance you can get a great deal of improvement. So electrolytic dressing is dominated electrochemical, mechanical action, supplemented by a complex method of trimming. 5.2 electrolytic dressing method is characterized by the electrolytic dressing method can facilitate the realization of metal bond diamond wheel ELID and shaping and sharpening can be done at the same time, easy to control the diamond cutting wheel surface state, the advantages of electrolysis dressing diamond grinding wheel is trimmed time is short, small grinding heat, avoid dressing diamond grinding wheel due to high temperature carbide diamond cup grinding wheel life leads to decline, the disadvantage is shaping electrolytic dressing method accuracy is not high, trimming the cost of larger, more complex process.
