Sintered metal binder diamond tools manufacturing process

Sintered metal binder diamond tools have been widely used in industry due to their excellent performance. This article will introduce the manufacturing process of sintered metal binder diamond tools.

Firstly, the raw materials used for the production of sintered metal binder diamond tools include diamonds, metal powders, and other additives. The diamonds used are usually synthetic diamonds of various sizes, and the metal powders include cobalt, nickel, iron, and their alloys. The additives can improve the toughness and wear resistance of the tools.

Secondly, the manufacturing process of sintered metal binder diamond tools can be divided into several steps. The first step is to mix the diamonds, metal powders, and additives uniformly. Then, the mixture is put into a mold and pressed to form a compact. The compact is usually in the shape of the desired tool, such as a circular saw blade or a drill bit.

The next step is to sinter the compact in a high-temperature furnace. During sintering, the metal powders melt and bond with the diamonds, forming a solid tool. The sintering temperature and time depend on the type of metal binder and the size of the tool. Generally, the sintering temperature is between 1300-1600℃, and the sintering time is several hours.

After sintering, the tool is subjected to a series of post-treatment processes, including grinding, polishing, and coating. Grinding and polishing can improve the surface finish and dimensional accuracy of the tool, while coating can enhance its performance, such as reducing friction and increasing wear resistance.

Finally, the quality control of sintered metal binder diamond tools is essential to ensure their performance and reliability. The quality control includes checking the physical and chemical properties of the raw materials, monitoring the sintering process parameters, and testing the finished tools' performance, such as cutting speed, tool life, and surface finish.

In conclusion, sintered metal binder diamond tools are an essential tool in the industry. The manufacturing process of sintered metal binder diamond tools involves mixing diamonds, metal powders, and additives, forming a compact, sintering, post-treatment, and quality control. The process requires precise control of parameters at each step, and the quality control is critical to ensure the performance and reliability of the finished tools.
