Grinding wheel arc finishing method

Abstract

The invention discloses a grinding wheel arc finishing method. According to the grinding wheel arc finishing method, the contour numerical value of a finishing wheel is obtained before machining, so that accurate feeding positions can be determined, excessive tool feeding time is avoided, and machining efficiency is improved; a theoretical outer contour line and a theoretical inner contour line are determined through obtaining the contour numerical value of a to-be-finished wheel, the theoretical outer contour line serves as the initial position during actual machining, and the theoretical inner contour line serves as the ending position during actual machining; and the offset between the theoretical outer contour line and the theoretical inner contour line is the finishing amount of the to-be-finished wheel, so that the feeding amount of each grinding can be set according to the finishing amount during actual machining, and the total feeding amount reaches the finishing amount; then the contour numerical value of the to-be-finished wheel is obtained through secondary detection, finishing of the grinding wheel is completed after the grinding wheel meets the requirement through comparison, and high-precision finishing of the grinding wheel is realized; and in addition, due to the fact that the finishing wheel and the to-be-finished wheel are arranged in a mutually vertical mode, so that more forms of curve movement can be realized between the two wheels, and more different forms of arcs can be finished.

Description

technical field [0001] The invention relates to the technical field of grinding wheel processing, in particular to a grinding wheel arc dressing method. Background technique [0002] With the continuous development of grinding wheel grinding technology, the requirements for dressing accuracy of grinding wheels of different materials and shapes are getting higher and higher. For the dressing of conventional grinding wheels on plane or end faces, the existing technology can basically meet the needs, but for irregular grinding wheels Contour dressing, dressing of grinding wheels of different materials, the existing technology cannot achieve a good dressing effect, even if it can be trimmed, it is time-consuming. Existing CNC shaped grinding wheel dressing machines or grinding wheel dressing and grinding machines all use diamond as a dressing tool to dress the grinding wheel, which is mainly aimed at the dressing of grinding wheels made of materials such as brown corundum, white...

[0002] With the continuous development of grinding wheel grinding technology, the requirements for dressing accuracy of grinding wheels of different materials and shapes are getting higher and higher. For the dressing of conventional grinding wheels on plane or end faces, the existing technology can basically meet the needs, but for irregular grinding wheels Contour dressing, dressing of grinding wheels of different materials, the existing technology cannot achieve a good dressing effect, even if it can be trimmed, it is time-consuming

Existing CNC shaped grinding wheel dressing machines or grinding wheel dressing and grinding machines all use diamond as a dressing tool to dress the grinding wheel, which is mainly aimed at the dressing of grinding wheels made of materials such as brown corundum, white corundum, and silicon carbide, which are commonly used in the market. Although the CNC shaped grinding wheel dressing machine can also do curved surface dressing, but for the sintered grinding wheel that requires higher dressing precision, it is not up to the requirement to use diamond for dressing. This is due to the high sintering hardness of the sintered grinding wheel. , Diamond also has wear and tear, so it is difficult to achieve high-precision dressing in this kind of dressing, and because the sintered grinding wheel has a high sintering density, the material is relatively hard and brittle, and the sintered grinding wheel will collapse during the grinding process when diamond is used for dressing
