Everyone who produces diamond grinding wheels knows that the important factor that affects the grinding performance of a grinding wheel is dressing, and reasonable dressing will affect the quality and grinding accuracy of the workpiece. So what is the soft elastic dressing method of the diamond grinding wheel?
The principle of the soft elastic dressing method of the diamond grinding wheel is that when dressing, the belt is put on the belt wheel. Due to the high-speed operation of the diamond grinding wheel, the winding theory will gradually roll, so that the belt will be driven. The touch force of the grinding wheel removes the bond between the abrasive grains on the surface of the diamond grinding wheel to achieve the purpose of dressing.
The dressing tool of the soft elastic dressing method, the abrasive belt is always touched by the dressing wheel with new sharp abrasive grains, which can form an outstanding dressing environment, remove the bond between the abrasive grains on the surface of the diamond grinding wheel, and the grinding force is small during dressing, the surface quality of grinding is high.
The dressing of the superhard abrasive wheel of the diamond grinding wheel is usually divided into two stages: shaping and sharpening. The purpose of shaping is to remove the shape error and surface defect of the grinding wheel after initial installation and to ensure the geometric shape precision of the grinding wheel. Sharpening is due to the passivation of the grinding wheel after working for a period of time. In order to make the cutting edge protruding the binder and having an appropriate height, sufficient chip tolerance space should be formed between the grinding grains, and the effective number of grinding grains per unit area should be as large as possible.
