Diamond grinding cup wheel dressing principle

This method of cbn grinding wheel dressing process, high-speed rotating grinding wheel, diamond grinding wheel connected to the positive supply and the negative electrode power tools, diamond grinding wheels and tools between the electrodes is injected into the grinding coolant, voltage is applied between the tool electrode and the grinding wheel Room will spark discharge between the diamond cup grinding wheel and trim adhesive metal electrodes, temperature instantaneous discharge of the metal binder vaporized metal bonded grinding wheel surface is effectively removed, diamond grains are fully exposed to achieve wheel dressing. Features 3.2 EDM finishing trim can be achieved online, easy to guarantee the accuracy of the grinding wheel, grinding force small wheel trimmed, high-precision shaping and shaping and sharpening can be completed at the same time, but the plastic slower and EDM diamond grinding wheel dressing because the discharge temperature is too high to make abrasive performance changes, effective control of the wheel surface temperature is the key to spark a diamond grinding wheel dressing.
