Re-griding-cutting cube boron-nitride grinding-block device, its base and grinding-block preparing method

Abstract

An automatic grinder device and the preparation method of grindstones relates to the mechanical field. It specially relates to a heavy grinding cubic boron nitride grindstone device of the heavy grinding double-sided high precision automatic grinder of various brake discs in automobile and aircraft aviation industry and the preparation method of its seat and grindstone. The device is composed of a seat, a grinder device and five cylinder CBN grindstones embedded on the alloy seat. The method contains preparation technology of the alloy seat, the sintering technology, fastening and binding method of five CBN grindstones. It mainly resolves the technologies of CBN grindstones device and the preparation method of its seat and grindstones. With its characterizes of multi-point cutting capability and small cutting resistibility, the invention has advantages of convenient clamping, strong rigidity, convenient tool setting and grinding at initial stage and high efficiency.

Description

technical field [0001] The invention relates to a fully automatic grinding machine equipment in the mechanical field and a method for preparing its base and grinding blocks, especially a kind of brake disc mainly used in the automobile industry, mainly for four-wheeled cars, and in the aviation industry. The invention discloses a cubic boron nitride grinding block device for heavy grinding of a double-face high-precision automatic grinding machine for heavy grinding of aircraft brake discs, a base and a preparation method of the grinding block. Background technique [0002] Most of the existing modules used in high-precision, high-cutting rate double-end high-end grinding machines are integrated GC or WA grinding blocks, which have poor wear resistance, prone to partial wear, short life and need to be replaced frequently. In order to solve this problem, some grinding machines use split CBN (Cubic Boron Nitride) abrasive tools, but the existing split CBN abrasive tools use a ...

AI Technical Summary

Problems solved by technology

[0007] The technical problems to be solved by the present invention are: mainly to solve the installation problems of the clamping fixed point, the arc-shaped R surface of the aluminum alloy base and the CBN cylindrical sintered body and the aluminum alloy bottom block; and also to solve the production and various tolerances of each component The problem of cooperation is to make the CBN cylinder have strong impact resistance and maintain a relatively uniform hardness; and to solve the problem that the aluminum alloy base should be a curved R surface, how to facilitate mixing with the movement track of the grinding wheel flange, and produce The problem of the cross-textured effect during grinding; after the preparation and sintering of 5 cubic boron nitride grinding blocks, the combination of the grinding block and the grinding wheel disc can be more closely, and the rigidity and safety of high-track grinding can be maintained; the aluminum How to fasten and combine the alloy base and 5 cubic boron nitride grinding blocks and how to reduce the time for clamping and tool setting and other related technical issues
