Abstract

The invention discloses a vertical offset correction method for a micro-diameter diamond ball-end milling cutter, and relates to the technical field of vertical offset correction of milling cutters. In order to solve the problem that a vertical offset correction method in the prior art is insufficient in precision, the vertical offset correction method comprises the steps of rough machining of a square feeler block, rough correction of cutter horizontal offset, rough correction of cutter vertical offset, two-axis linkage ultra-precision milling machining of the square feeler block, trial cutting calibration of the difference value of the upper edge and the lower edge of any end face of the square feeler block in the X-axis direction, calculation of the cutter Y-direction offset direction and offset amount, correction of the cutter Y-direction offset amount and trial cutting verification after offset correction. According to the correction method, the vertical offset of the ultra-precision diamond ball-end milling cutter can be precisely corrected, the vertical offset error of the milling cutter after correction can be smaller than 0.5 micron, and development of the multi-axis ultra-precision milling machining technology in China can be promoted.
