Diamond ball head grinding wheel electric sparkle dressing cutter adjustment method based on two-time cutter adjustment process

Abstract

The invention discloses a diamond ball head grinding wheel electric sparkle dressing cutter adjustment method based on two-time cutting tool process, and relates to a ball head grinding wheel electric sparkle dressing cutter adjustment method. The purpose of the invention is to improve the accuracy of cutter adjustment in dressing a grinding wheel, so as to improve the surface shape accuracy of the diamond ball head grinding wheel which is dressed. The main technical core of the invention is: firstly, the relative mounting positions of a grinding wheel spindle and a electrode spindle are precisely adjusted before grinding wheel dressing, so that the axial lines of the grinding wheel spindle and the electrode spindle form an angle of to 45 degrees and intersect at a point; secondly, first-time cutter adjustment is performed on a small-diameter diamond ball head grinding wheel, and the grinding wheel is dressed for the first time; finally, two newly formed edge feature points of the grinding wheel are selected to realize the second cutter adjustment of the small-diameter diamond ball head grinding wheel. The second cutter adjustment after the first cutter adjustment can effectively eliminate the influence of manufacturing errors of the grinding wheel and judgment errors of the edge feature points on the cutting tool accuracy; under the same conditions, the two-time cutter adjustment process can reduce cutter adjustment errors by 30% to 70%.

Description

technical field [0001] The invention relates to a tool setting method for electric spark trimming of a small-diameter diamond ball head grinding wheel. Background technique [0002] With the increasing development of science and technology, free-form surfaces, especially high-precision small-sized parts with complex shapes and special-shaped surfaces, play an extremely important role in the fields of aviation, aerospace and military affairs. For the ultra-precision grinding of such parts, due to its Due to the complexity of the surface shape, it is difficult to meet the processing requirements with conventional diamond grinding wheels, and the grinding wheel is extremely easy to interfere with the workpiece during processing. Therefore, small-diameter (φ2~10mm) metal-based diamond ball-head grinding wheels are often used for ultra-precision grinding of such parts. In the grinding process of complex curved surface parts, the surface shape accuracy and abrasive grain sharpnes...
