Problems solved by technology

Generally speaking, "dry pressing molding" is a diamond wheel blank manufactured by using granulated materials, and its internal density uniformity is poor
[0004] Based on this, the applicant thinks that existing emery wheel, especially emery wheel is manufactured with the technology of dry pressing forming method and still needs to be improved
In addition, there is also the production process of electroplated diamond grinding wheel. Since the adhesion of the electroplated diamond grains is not strong, it is easy to fall off during grinding, resulting in a decrease in the grinding effect, and the short service life of the electroplated diamond grinding wheel, so the strong grinding is interrupted. Electroplated diamond grinding wheel is not selected

Embodiment Construction

[0017] A method for manufacturing a grinding wheel of the present invention comprises the following steps: firstly, the metal powder mixture containing abrasives is used as a raw material, and an injection molding process is used to prepare a grinding wheel blank, and then the grinding wheel blank is sequentially subjected to a debonding process, a sintering process, and finally an electric Spark trimming into finished product

[0018] In this embodiment, the injection molding process is carried out using an injection molding machine, including injecting the metal powder mixture containing abrasives into the mold cavity under high temperature and high pressure to generate a grinding wheel blank, wherein the high temperature is 180°C ± 30°C, The high pressure is 70Mpa±25Mpa.

[0019] combine figure 1 As shown, the specific process of the injection molding process is as follows:

[0020] Put the metal powder mixture containing abrasive into the hopper 1, squeeze it through the...

Abstract

The invention discloses a method for manufacturing a grinding wheel, which belongs to the technical field of grinding wheel production, and comprises the following steps: firstly, a metal powder mixture containing abrasives is used as a raw material, and an injection molding process is adopted to prepare a grinding wheel blank, and then the grinding wheel blank is sequentially debonded process, sintering process, and finally trimmed by EDM into finished products. The internal material of the grinding wheel blank produced by the invention has good uniformity. After sintering, the finished product has high density and high breaking strength, which is convenient for subsequent debonding, sintering and EDM repairing. Finally, the finished product has a strength and grinding sharpness that meet the requirements for use. Grinding wheel.

Description

technical field [0001] The invention discloses a method for manufacturing a grinding wheel, which belongs to the technical field of grinding wheel production. Background technique [0002] In conventional machining, grinding wheels are called machining teeth, which are often used in machining of hard materials. Grinding wheels are generally made by "dry pressing". Among them, the diamond grinding wheel is often selected in the grinding process because of its superhard performance. In grinding, the sharpness and dressability of the grinding wheel are important performance indicators. In the existing technology, the emery wheel is usually made by "dry pressing" to make the emery wheel blank, and then the subsequent sintering, trimming and other processes are carried out; or it is made by electroplating emery. [0003] If the diamond grinding wheel is made by "dry pressing", the internal uniformity and density of the blank are directly related to the quality of the fin...
