When it comes to diamond cutting blade, many people may be very unfamiliar. In fact, diamond saw blades are a cutting tool that is widely used in the processing of hard and brittle materials such as stone and ceramics.

The diamond saw blade is mainly composed of two parts: the base body and the knife. The matrix is the main support part of the bonding cutter head, and the cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the matrix will not. The reason why the cutter head can cut The function is because it contains diamond. As the hardest substance at present, diamond rubs and cuts the processed object in the cutter head, and the diamond particles are wrapped inside the cutter head by metal. Diamond saw blades are widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone materials, and ceramics.

Diamond Tools manufacture

Manufacturing process classification of diamond saw blades   

1. Sintered diamond saw blade: divided into two types: cold pressing and hot pressing, which are pressed and sintered.   

2. Welding diamond saw blades: divided into high-frequency welding and laser welding. High-frequency welding welds the cutter head and the substrate together through a high-temperature melting medium, and laser welding uses a high-temperature laser beam to melt the contact edge of the cutter head and the substrate to form a metallurgical bond .   

3. Electroplated diamond saw blade: the blade powder is attached to the substrate by electroplating.

Application range of diamond saw blades   

  1. Processing of difficult-to-machine non-ferrous metal materials   

When processing non-ferrous metals such as copper, zinc, aluminum and their alloys, the material is easy to adhere to the tool, making it difficult to process. Utilizing the characteristics of low friction coefficient of diamond and low affinity with non-ferrous metals, diamond tools can effectively prevent metal and tool from bonding. In addition, due to the large elastic modulus of diamond, the deformation of the blade during cutting is small, and the extrusion deformation of the non-ferrous metal to be cut is small, so that the cutting process can be completed with small deformation, thereby improving the quality of the machined surface.   

2. Processing of difficult-to-machine non-metallic materials 


When machining difficult-to-machine non-metallic materials containing a large number of high-hardness particles, such as glass fiber reinforced plastics, silicon-filled materials, and hard carbon fiber/epoxy composite materials, the hard points of the material cause serious tool wear, and it is difficult to use carbide tools. The diamond tool has high hardness and good wear resistance, so the processing efficiency is high.

3. Ultra-precision machining   

With the advent of modern integrated technology, machining is developing towards high precision, which puts forward quite high requirements for tool performance. Due to the small friction coefficient, low thermal expansion coefficient and high thermal conductivity of diamond, it can cut extremely thin chips. The impact on the blade and the workpiece, so the blade is not easy to passivate, the cutting deformation is small, and a higher quality surface can be obtained.
