|Title||Method for dressing bowl type diamond grinding wheel by GC cup grinding wheel|
|Description||The dressing of superabrasive grinding wheels for diamond wheels is usually divided into two stages: shaping and sharpening. Shaping is a micro-cutting of the China cutting disc for metal. The purpose is to remove the shape error and surface defects of the grinding wheel after initial installation to ensure the geometric accuracy of the grinding wheel. The sharpening is due to the passivation of the grinding wheel after working for a period of time. In order to make the cutting micro-blade protrude the bonding agent and have an appropriate height, a sufficient space for chipping is formed between the abrasive grains, and the number of effective abrasive grains per unit area is as large as possible. The actual geometrical relationship between the GC cup wheel and the bowl diamond wheel is shown in the figure. The bowl-shaped diamond grinding wheel and the GC cup-shaped grinding wheel are completely interlaced and rotated at a certain speed. The rotation speed of the dressing wheel and the grinding wheel is 8:1. The dressing wheel is fixed, and the diamond grinding wheel is trimmed and fed in the axial direction, so that the GC cup grinding wheel and the bowl type diamond grinding wheel form mutual abrasive grinding. Through the grinding of the end faces of the two grinding wheels, the passivation abrasive grains of the low price disc for metal are removed to form a chip space, and the surface of the diamond grinding wheel is re-sharpened to achieve the purpose of dressing.|
