Grinding method and device for axisymmetric components

Abstract

The present application discloses a grinding method and device for axisymmetric components. The method includes: respectively determining the amount to be ground corresponding to the discrete points of the first circle, the second circle, ···, the path of each segment on the Nth circle on the surface to be ground of the axisymmetric component; Grinding amount, respectively determine the different rotational speeds corresponding to the axisymmetric components when the grinding head grinds the discrete points of the first circle, the second circle, ···, the Nth circle on each segment path; control The grinding head grinds the discrete points of each path on the first circle, the second circle, ···, the Nth circle in turn, and when the grinding head is grinding, the axis-symmetrical components are controlled to correspond to each path. rotation speed. The method can effectively reduce the number of axes of the numerical control machining system required for high-precision grinding, improve the accuracy and efficiency of the moving trajectory of the grinding head, and improve the grinding quality and efficiency.

Description

technical field [0001] The present application relates to the technical field of manufacturing, and in particular, to a grinding method and device for axisymmetric components. Background technique [0002] As the market's demand for optical consumer goods such as mobile phones, cameras, video cameras, drones, and projectors continues to expand, the processing industry of optical components (such as spherical lenses, aspherical lenses, etc.) is also developing. Taking an aspherical lens as an example, the common processing method for aspherical lenses is to use traditional CNC machine tools to rough them, then use precision CNC machine tools to finish them, and then use grinding and polishing CNC machine tools to grind and polish them. 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 optical...
