Anti-deformation glass drilling and chamfering grinding tool

Abstract

The invention relates to an anti-deformation glass drilling and chamfering grinding tool. The grinding tool comprises a base and a sawtooth-shaped ring used for glass chamfering, and the sawtooth-shaped ring comprises a plurality of chamfering grinding teeth; and the base is in the shape of a circular block, the chamfering grinding teeth are densely arranged on the end face of the base in the circumferential direction, the end faces, away from the base, of the chamfering grinding teeth are working faces, and gaps between the adjacent chamfering grinding teeth form water grooves used for water passing. The sawtooth-shaped ring is formed by the multiple independent chamfering grinding teeth, an existing chamfering grinding tool with an integral continuous grinding face is replaced, the sawtooth-shaped ring has an anti-deformation function during glass chamfering, and the problem of shape losing and failure is solved; and the cooling mode of the chamfering grinding tool is changed into a main inner cooling manner from a main outer cooling manner in the prior art through the multiple water grooves formed between the chamfering grinding teeth, a multi-water-channel water supply manner is formed, and efficient machining can be achieved.

Description

technical field [0001] The invention relates to the technical field of chamfering abrasive tools, in particular to an anti-deformation glass drilling chamfering abrasive tool. Background technique [0002] In the prior art, the chamfering abrasive tool matched with the glass drill bit is generally a powder metallurgy diamond abrasive tool of homogeneous material, which is used for chamfering the rear port of the glass drilling hole. The amount is the largest, the axial processing amount at the large diameter is the smallest (it tends to 0), the axial height processed per unit circumference at the small diameter is the maximum, and the axial height processed per unit circumference at the large diameter is the minimum (Tends to 0), the axial height processed per unit circumference at each point between the small diameter and the large diameter changes linearly. For the chamfering part, from the diameter to the large diameter, the axial processing amount changes linearly from ...

AI Technical Summary

Problems solved by technology

[0005] The beneficial effects of the present invention are: the serrated ring is formed by a plurality of independent chamfering grinding teeth, which replaces the existing chamfering grinding tool with integral continuous grinding surface. It has the function of anti-deformation, which solves the problem of loss of shape and failure; multiple water tanks formed between multiple chamfering grinding teeth convert the cooling of the chamfering grinding tool from the main external cooling of the original technology to the main internal cooling method, forming a multi-channel Water channel water supply mode can realize efficient processing
