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, ceramics and so on. The diamond saw blade is mainly composed of two parts; the base body and the cutter head. The base is the main supporting part of the bonded cutter head.

Process classification of diamond saw blade
The diamond saw blade cutter head is the part that cuts during use. The cutter head will continue to be consumed during use, while the matrix does not. The reason why the diamond saw blade cutter head can cut is because it contains Diamond, as the hardest substance at present, diamond friction cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head.
l Sintering diamond saw blade: It is divided into two types, cold pressing sintering and hot pressing sintering, and it is made by pressing and sintering.
l Welding diamond saw blade: It is divided into two types: brazing and laser welding. Brazing is to weld the cutter head and the substrate through a high-temperature melting medium, such as high-frequency induction brazing saw blades, vacuum brazing saw blades, etc.; laser welding passes high temperature The laser beam melts the contact edge of the cutter head and the substrate to form a metallurgical bond.
l Electroplating (brazing) diamond saw blade: is to attach the blade powder to the substrate by electroplating. Starting in 2012, the country is gradually canceling the production of electroplated diamond products, mainly because the pollution is quite serious.
Appearance classification of diamond saw blade
① Continuous edge diamond saw blade: continuous saw tooth diamond saw blade, generally made by sintering method, usually bronze bond is used as the basic matrix material, water must be added during cutting to ensure the cutting effect, and the type of cutting gap with the laser head
② Diamond saw blade: The saw teeth are broken and the cutting speed is fast. It is suitable for both dry and wet cutting methods.
③ Turbine-type diamond saw blade: Combining the advantages of the first and second items, the serrations continuously present a turbine-like uniform convexity, which improves the cutting speed and increases the service life.
④ Different types of diamond saw blades are selected for different materials, and different powder formulations are suitable for the characteristics of different materials, which have a direct impact on the quality, effect, pass rate, and cost and benefit of the material product.
⑤ The factors that affect the efficiency and life of diamond saw blades include sawing process parameters, diamond particle size, concentration, and bond hardness. According to the cutting parameters, there are saw blade linear speed, sawing concentration and feed speed.
Diamond saw blade quality standard analysis.
l Life and sharpness
When the diamond concentration changes from low to high, the sharpness and sawing efficiency of the diamond saw blade will gradually decrease, which will gradually extend the life, but if the concentration is too high, the diamond saw blade will become dull. With low concentrations, the efficiency is improved. Therefore, in the manufacturing process of the diamond saw blade, the diamond concentration should be reasonably controlled according to different cutting objects and machines used, so that the diamond can be fully utilized during the use process.
Introduction to sawing parameters of diamond saw blade.
Diamond saw blade speed:
In actual work, the linear speed of diamond circular saw blades is limited by the equipment conditions, the quality of the saw blade and the nature of the sawn stone. From the perspective of the best saw blade service life and sawing efficiency, the linear speed of the saw blade should be selected according to the properties of different stones. When sawing granite, the linear speed of the saw blade can be selected within the range of 25m～35m/s.
diamond saw blade cutting depth
The cutting depth is an important parameter related to diamond wear, effective sawing, the force of the saw blade and the properties of the sawn stone. Generally speaking, when the linear speed of the diamond circular saw blade is high, a small cutting depth should be selected. According to the current technology, the cutting depth of diamond can be selected between 1mm and 10mm. Generally, when large-diameter saw blades are used to cut granite blocks, the cutting depth can be controlled between 1mm and 2mm. At the same time, the feed speed should be reduced. When the linear speed of the diamond circular saw blade is large, a large cutting depth should be selected.
diamond saw blade feed speed
The feed speed is the feed speed of the sawn stone. Its size affects the sawing rate, the force of the saw blade and the heat dissipation of the sawing area. Its value should be selected according to the nature of the stone being sawn. Generally speaking, when sawing soft stone, such as marble, the feed speed can be appropriately increased. If the feed speed is too low, it is more conducive to increase the sawing rate. For sawing fine-grained, relatively homogeneous granite, the feed speed can be appropriately increased. If the feed speed is too low, the diamond blade will be easily polished.
At present, there are still some key problems to be solved in the industrialization of diamond, such as high-speed large-area diamond thick film deposition process, control of the grain boundary density and defect density of the diamond film, low-temperature growth of the diamond film, and the bonding force between the diamond film and the substrate. Weak and so on. The excellent performance and broad development prospects of diamond saw blade have attracted countless experts at home and abroad to conduct research. Some of them have made breakthrough progress. It is believed that diamond saw blade will be widely used in modern processing in the near future.
