2020 China New Design resinoid bond- Special sintered diamond cold pressed sheet for angle grinder – Kemei

1. Continuous edge saw blade: the continuous serrated diamond cutting blade is generally made by sintering method. The bronze bond is commonly used as the basic matrix material. When cutting, water must be added to ensure the cutting effect, and laser is used to cut the type of gap.
2. Cutter head type cutting slice: sawtooth is broken, cutting speed is fast, suitable for dry and wet cutting methods.
3. Turbine type cutting blade: combined with the advantages of the front 1 and 2, the saw tooth continuously presents turbine like uniform convex concave, which improves cutting speed and service life.

Different materials choose different kinds of diamond saw blades, different powder formula is suitable for different material characteristics, which has a direct impact on the quality, effect, qualified rate, cost and benefit of material products.
The factors that affect the efficiency and life of diamond circular saw blade are cutting process parameters, diamond particle size, concentration, bond hardness and so on. According to the cutting energy, there are saw blade linear speed, cutting concentration and feed speed.
It is closely related to the cutting efficiency, cutting quality and service life of the saw blade whether the installation of the diamond circular saw blade is correct or not and the installation accuracy. After installation, it is necessary to ensure that the saw blade operates stably and does not produce vibration during the cutting process (except for the influence of the saw blade’s own quality and the rigidity of the cutting machine).
When installing the saw blade, first of all, make sure that the cutting direction indicated on the saw blade is consistent with the rotation direction of the main shaft of the cutter; to clean up the contact surfaces of the installation hole of the saw blade, the main shaft of the cutter and the flange plate, it is necessary to ensure that the contact between them is smooth and good; the diameter of the flange plate should be reasonably selected according to the diameter of the saw blade. If the flange is too small, the end face of the saw blade will swing large. If the flange is too large, the main shaft hanging weight will increase, which will also increase the runout and reduce the processing depth of materials.
