Elastic grinding and polishing small grinding head tool

Abstract

The invention relates to a grinding head for machining of precision optical elements, and provides an elastic grinding and polishing small grinding head tool. A polishing disc and the surface of the tool are high in goodness fit. The elastic grinding and polishing small grinding head tool is provided with a spindle, bolts, gaskets, an elastic element, a base and a fixed grain grinding wheel sheet. The axis of the spindle, the axis of the base and the axis of the elastic element coincide. The elastic grinding and polishing small grinding head tool is provided with no inflation structure; the elastic element is arranged between the spindle and the base; the spindle and the base are located through a concave-convex sliding block structure; the base and the spindle are connected through the bolts and the gaskets in a matching manner; and the fixed grain grinding wheel sheet is attached to the base. The elastic element is added, no inflation structure is arranged, and therefore goodness fit of the small grinding head polishing disc and the surface of the tool is greatly improved, and the machining quality of the surface of the workpiece is improved. Machining of pasting the fixed grain grinding wheel sheet is adopted so that efficiency can be improved, and precision can be guaranteed.

Description

technical field [0001] The invention relates to a grinding head used for processing precision optical elements, in particular to a small grinding head tool for elastic grinding and polishing. Background technique [0002] With the development of industrial technology, there are more and more demands for precision optical components in engineering. At present, the finishing of optical components mainly adopts the processing method of first grinding and then polishing. Among the many polishing methods, small grinding head polishing is the earliest CCOS technology. [0003] The general working process of the small grinding head is as follows: firstly, the initial surface shape of the surface of the workpiece to be polished is measured by interferometer and other measuring equipment; then the measured initial surface shape is imported into the computer, and the residence time is calculated by combining the removal function of the small grinding head and Generate a code program ...

AI Technical Summary

Problems solved by technology

Due to the rigid structure of the main body of the tool head of the small grinding head, the degree of fit between the polishing disc of the small grinding head and the surface of the tool is poor, which affects the processing quality

In addition, the removal amount of the small grinding head is small, and the polishing efficiency is low
