Problems solved by technology
There is a boss in the middle of the traditional aluminum substrate. After the working layer of the grinding wheel is pressed, the boss is removed when the finished product is processed. It takes a lot of processing time. In addition, special care must be taken when removing the boss close to the working layer, otherwise, Easy to damage the working layer of the grinding wheel and the turning tool

Embodiment Construction
[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0014] exist figure 1 In , taking a bowl-shaped grinding wheel as an example, it includes a working layer 1 and an aluminum substrate 2 .
[0015] exist figure 2 Among them, the cross-section of the aluminum substrate in the prior art has bosses 3 .
[0016] exist image 3 Among them, the aluminum matrix of the present invention has a rectangular cross section. In the aluminum matrix of the invention, the original boss in the middle of the matrix is removed, and the total thickness of the grinding wheel matrix is reduced. In this way, the aluminum substrate after the improved design does not need to change the original mold and sintering process. Can.

The invention aims at providing an aluminum substrate of a diamond grinding wheel. The aluminum substrate is low in cost and simple in process. The cross section of the aluminum substrate is rectangular, and a ring compression method is adopted during sintering.
Description
technical field [0001] The invention relates to a design technology for manufacturing an aluminum matrix of a resin bonded diamond grinding wheel. Background technique [0002] The circular bonded abrasive with a through hole in the center made of diamond abrasives as raw material and resin powder as a bond is called a diamond resin bonded grinding wheel. The structure of the diamond resin bonded grinding wheel generally consists of three parts: the working layer (that is, the diamond layer), the metal matrix, and the transition layer. Diamond grinding wheels are used for grinding of hard and brittle materials such as glass, ceramics, ferrite, semiconductor materials and metal materials, shape processing of cemented carbide materials, electrolytic grinding, and grinding of diamond drills for grinding centers, etc. Heavy-duty cutting, with the characteristics of good grinding wear resistance, high efficiency and long service life. Diamond grinding wheels are available in bo...
