The Diamond Saw Blade for Granite is a cutting tool, which is widely used in the processing of hard and brittle materials such as stone and ceramics. The Diamond Saw Blade for Granite is mainly composed of two parts; the base and the blade. The substrate is the main support part of the bonded blade, and the blade It is the part that cuts during use. The cutter head will continue to be consumed during use, but the matrix will not. The reason why the cutter head can cut is because it contains diamond, which is currently the hardest Substance, it friction cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head.

In the process of use, the metal matrix is ​​consumed together with the diamond. Generally, the ideal situation is that the metal matrix consumes faster than the diamond, so as to ensure the sharpness of the cutter head and ensure the cutter head has a longer life.

Classification of Diamond Saw Blade for Granites

More and more industries use Diamond Saw Blade for Granites in the production process. With the integration and subdivision of the industry, the types of Diamond Saw Blade for Granites are becoming more refined.

Manufacturing process classification:

1. Sintered Diamond Saw Blade for Granite: It is divided into cold pressing sintering and hot pressing sintering.

2. Welding Diamond Saw Blade for Granites: divided into high-frequency welding and laser welding. High-frequency welding uses a high-temperature melting medium to weld the cutter head and the substrate together. 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 for Granite: the blade powder is attached to the substrate by electroplating.

Appearance classification:

1. Continuous edge saw blade: Continuous serrated Diamond Saw Blade for Granite, generally made by sintering method. Bronze bond is commonly used as the base matrix material. Water must be added during cutting to ensure the cutting effect, and the type of cutting gap with a laser.

2. Knife-head saw blade: the saw teeth are broken, the cutting speed is fast, and it is suitable for dry and wet cutting methods.

3. Turbine saw blade: Combining the advantages of the first and second two items, the serrations continuously present a turbine-like uniform convexity, which improves the cutting speed and increases the service life.

Different types of Diamond Saw Blade for Granites are selected for different materials, and different powder formulas 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.

The factors that affect the efficiency and life of diamond circular saw blades include sawing process parameters, diamond particle size, concentration, and bond hardness. According to the cutting energy number, there are saw blade linear speed, sawing density and feed speed.

One, sawing parameters

(1) Saw blade linear speed: In actual work, the linear speed of diamond circular saw blades is limited by equipment conditions, saw blade quality and the nature of the sawn stone. In terms of the best service life and cutting efficiency of the saw blade, 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 in the range of 25m～35m/s. For granite with high quartz content and difficult to saw, the lower limit of the saw blade linear speed is appropriate. In the production of granite tiles, the diameter of the diamond circular saw blade used is small, and the linear speed can reach 35m/s.

(2) Sawing depth: Sawing 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. From the current technology, the cutting depth of diamond can be selected between 1mm and 10mm. Generally, when large-Diamond Saw Blade for Granites are used to cut granite blocks, the cutting depth can be controlled between 1mm and 2mm, and the feed speed should be reduced at the same time. When the linear speed of the diamond circular saw blade is large, a large cutting depth should be selected. But when the sawing machine performance and tool strength allowable range, the cutting concentration should be as large as possible for cutting to improve cutting efficiency. When there are requirements for the machined surface, small depth cutting should be used.
