Description

A diamond saw blade

technical field

The utility model relates to the technical field of diamond tools, in particular to a diamond saw blade.

Background technique

With the development of society and the continuous improvement of people's living standards, the scale and quantity of infrastructure construction and home decoration have increased significantly. What followed was the use of various cutting tools.

Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics. Diamond saw blades are mainly composed of two parts; the base body and the cutter head. The substrate is the main supporting part of the bonded cutter head, while the cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the substrate will not. The reason why the cutter head can cut The role of diamond is because it contains diamond, which is currently the hardest substance, and it rubs and cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head.

In today's market, diamond saw blades have been widely used in the cutting and processing of materials such as marble, granite, concrete, asphalt, ceramics, glass, jewelry and jade, and semiconductors. Continuously improving product efficiency, reducing material loss, and improving economic benefits are the common pursuit of the market.

Diamond saw blades can be divided into two categories from the combination of the cutter head and the metal substrate: the first type is that the cutter head is welded to the metal substrate after being sintered separately; The cutter head is combined with the metal matrix, and then sintered to make the two firmly bonded. According to the shape of the cutter head, it can be divided into continuous cutter head type diamond saw blade and spaced cutter head type diamond saw blade.

Traditional diamond tools are generally mixed with diamond and metal powder, manually weighed, loaded into a mold, and then hot-pressed or cold-pressed and then sintered. The diamond head and the substrate of the diamond saw blade currently used are usually welded. The method is fixed, but when the diamond saw blade is running at high speed, the processing resistance is large, especially when encountering a large lateral resistance, the cutter head is easy to fall off, causing a safety accident, and also reducing the service life of the cutter head.

At the same time, the diamond saw blade also has the problem of slow working cooling and heat dissipation. Moreover, sometimes there are problems such as poor chip removal, poor water cooling effect, and insufficient strength of the cutter head.
