Processes Often Used By Diamond Saw Blades

There are also several small saw blades with different shapes in the design shape of the diamond saw blade, and the saw blade experiment is carried out. Analyze how the shape and structure of the saw blade will affect the sharpness of the saw blade, and find a suitable design, the shape and structure of the diamond saw blade can improve the sharpness of the saw blade.

Today, Xiaobian will take you to understand the processes that are often used to make successful diamond saw blades.

1. The process of sintering the diamond saw blade:

This sintering process can be divided into two types: one is cold-pressed sintering, and the other is hot-pressed sintering. Through the production of these two sintering methods, the diamond saw blade can be successfully produced.

2. The process of making diamond saw blades by welding:

This process can be divided into three types: one is high-frequency welding, the other is laser welding, and the third is brazing. One type of welding machine is to combine the medium with the matrix after melting the medium with high temperature. The second is to use a high-temperature laser beam to combine the substrate and the cutter head. The third is to use the flame spraying method to plate the raw materials belonging to the alloy on the substrate.

The above two are the processes that are often used to make diamond saw blades.

The design principle of the diamond saw blade, the diamond configuration in the diamond saw blade is extremely important, it is not only directly related to the cost of the cutter head, but also has a great impact on the cutting performance. The difference between domestic and foreign manufacturing technology mainly lies in the selection of diamonds. Foreign countries generally use low concentration (20~30%), large particles (-20 mesh), and high strength (greater than 300N) to ensure cutting efficiency and quality. Due to the limitation of diamond synthesis technology in China, diamond selection varies greatly. The difference in saw blade performance is also mainly in this.

In China, high concentration (greater than 35%), medium and low strength (80~160N) and wide grain size range (30/35~70/80) are generally selected to meet the requirements for tool life by losing part of the cutting efficiency and quality. The reason why manufacturers choose mixed-strength grain size diamonds is that, in addition to being limited by the source of diamonds, it is generally believed that it is easy to obtain appropriate comprehensive performance and cost, and to improve the adaptability of the cutter head to the processing object. Diamond is mainly selected according to different processing objects, from three interrelated aspects: strength, particle size and concentration.

Under the premise of firmly holding the diamond to give full play to its performance, the diamond saw blade bond must also wear synchronously with the diamond to form a new cutting edge. The coordination between the diamond, the binder and the processing object is the most difficult to master and control in the manufacture of diamond saw blades. For example, as the diameter of the saw blade increases, the sawing force increases, a higher grade of diamond is required, and the wear resistance of the bond should also be improved accordingly.
