Grinding method and device for axial symmetry component

Abstract

The invention discloses a grinding method and device for an axial symmetry component. The method comprises the steps of respectively determining the to-be-ground amount corresponding to discrete points of all paths on a first circle, a second circle, and the like, and an Nth circle of a to-be-ground surface of the axial symmetry component; according to the to-be-ground amount, respectively determining different rotating speeds corresponding to the axial symmetry component when a grinding head grinds the discrete points of all the paths on the first circle, the second circle, and the like, and the Nth circle; and controlling the grinding head to grind the discrete points of all the paths on the first circle, the second circle, and the like, and the Nth circle in sequence, and when the grinding head grinds the discrete points, controlling the axial symmetry component to rotate at the rotating speeds corresponding to all the paths. According to the method, the number of shafts of a numerical control machining system required by high-precision grinding machining can be effectively decreased, the accuracy and efficiency of the moving track of the grinding head are improved, and the grinding quality and efficiency are improved.

Description

technical field [0001] The present application relates to the field of manufacturing technology, in particular to a grinding method and device for axisymmetric components. Background technique [0002] As the market demand for optical consumer goods such as mobile phones, cameras, video cameras, drones, and projectors continues to expand, the processing industry for optical components (such as spherical lenses, aspheric lenses, etc.) is also developing day by day. Taking an aspheric lens as an example, the commonly used processing method of an aspheric lens is to use a traditional CNC machine tool to rough it, then use a precision CNC machine tool to finish it, and then use a grinding and polishing CNC machine tool to grind and polish it. Among them, the grinding and polishing process is an indispensable and important link in the production process of optical components, and the trajectory of grinding and polishing is an important factor affecting the surface accuracy of opt...
