Method for roughly trimming diamond grinding wheel

Abstract

The invention provides a method for roughly trimming a diamond grinding wheel. The method includes steps of A, scanning the surface of the diamond grinding wheel, acquiring the highest point of the surface of the grinding wheel and determining the position of the highest point in radial, axial and generating line directions; B, emitting a focused pulse laser beam along the inner normal direction of the surface of the grinding wheel and enabling the position of a focal spot of the focused pulse laser beam to be coincided with the position of the highest point of the grinding wheel in the radial, axial and generating line directions; C, erecting a silicon carbide roller at a position opposite to a generating line of the grinding wheel and setting the cutting depth as 0.005mm; and D, repeating the steps once after the grinding wheel is trimmed for 3 to 5 minutes until a circle run-out error of the grinding wheel is not larger than 20 micrometers. The method has the advantages that diamond grains are ablated and directly removed by the focused pulse laser beam, remaining diamond grains are removed by the silicon carbide roller, deteriorative layers of surfaces of the grains which are ablated by laser, grains without holding force and the like are mechanically peeled off, and the method is applicable to efficiently roughly trimming diamond grinding wheels with large grains.

Description

technical field [0001] The invention relates to the technical field of dressing of diamond grinding wheels, in particular to a rough dressing method of diamond grinding wheels. Background technique [0002] Diamond is the hardest material today, with a small friction coefficient and good wear resistance. Therefore, the superabrasive diamond grinding wheel made of diamond has the characteristics of strong grinding ability, small consumption of abrasive tools, and low grinding temperature. It is widely used in the processing of hard and brittle materials such as glass, stone, concrete, ceramics, and cemented carbide. The consumption is increasing at a rate of about 10% per year, saving a lot of grinding time and processing costs. [0003] At present, for the grinding of the diamond grinding wheel itself, the mechanical roller dressing method based on "head-to-head" is basically used, such as turning dressing method, diamond roller dressing method, grinding dressing method, rol...
