To improve the maintenance of abrasive tools, follow the maintenance of five stainless steel fasteners and gold plastic, and carry out quenching and stress relief on the mold of abrasive tools on time.

Die-casting mold parts have been continuously produced under high pressure, high speed, and high temperature, and the application standards are relatively extreme. Abrasives can cause damage or common failure safety hazards during the entire application process. Therefore, it is very important to improve the maintenance of the abrasive tools, carry out maintenance on the abrasive tools on time, replace the damaged position, replace the spare parts, remove the ropeway, small chain holes, etc. The reliability of the tool can also increase the service life of the abrasive tool.

In addition, because the die-casting mold parts are continuously damaged in the application, and the continuous thermal expansion and contraction will cause new thermal stress. Therefore, it is also a key way to increase the service life of abrasive tools to carry out in-situ stress quenching on the die of the abrasive tool on time to remove the in-situ stress. Under normal circumstances, after the abrasive tool is delivered for use, the first metal product processing and quenching should be carried out after 3000-5000 mold times. In the future, according to the application conditions, generally every 10,000 abrasive tools are produced, it is necessary to carry out stress relief quenching on the abrasive tool concave mold, which can greatly increase the service life of the abrasive tool.
