Problems to be solved in order to guarantee quality by cold pressing of diamond segment

Publish Date:2020-04-27
In order to guarantee the quality and improve the production efficiency, there are two problems in the cold pressing of diamond segment, especially in the automatic cold press.

First, how to ensure that the amount of diamond in each segment is the same and that the diamond is evenly distributed in the binder;

Second, in mass production, what kind of measurement method can be used to ensure the accuracy of each segment and the high efficiency.

To solve the above two problems. In foreign countries, it is introduced to make materials, that is, after the diamond and binder are mixed evenly, they are made into granular mixture. There are also some enterprises in China. This technology has long been a mature technology in the production of cemented carbide and magnetic materials, but the application research in diamond tool manufacturing is relatively lagging behind, but now many manufacturers are starting to use the material manufacturing technology.

After the sintering of diamond segment, the die can be taken out from the hot press by holding pressure and cooling to about 600 degree, and then it can be cooled to room temperature by fan to take out the segment.

The control ratio of the metal content in the diamond segment bond

2020-08-17
The diamond segment is composed of two parts of the bond and the diamond, and the bond is actually not just one component, it is made of paraffin, nickel, tin, zinc, copper, iron, silicon carbide, tungsten and other metal powders, and non-metallic powder, in which copper, iron, silicon carbide and tungsten are the main components, while nickel, tin, and zinc are the metal binders, which make the diamond and the bond more firmly....

Selection of diamond powder for diamond segment

During the diamond segment working process, the role of diamond powder crystals is very important, especially in the cutting process, a good crystal can be very good in anti-breakage ability, reduce the power consumption of the equipment, and extend the life of the cutting....

Arrayed diamond segment and the saw blade

2020-12-29
In traditional diamond segment products, the diamond powder in the segment is arranged in disorder. During the cutting process, the exposed diamond will impact the stone surface at various angles, and the exposed height of the diamond will vary. As a result, the diamond is not evenly stressed, and diamonds with high exposure are prone to fracture. In order to improve this situation and make the diamond distribution more uniform, arrayed segments have emerged. Weld the arrayed segment on the blade steel body to be an arrayed saw blade....

Commonly used bond for diamond segment
