CONSTRUCTION SAW BLADE
How to choose diamond circular saw blades correctly?
1. Saw blade structure size selection. You should be familiar with the conventional structure and size of the circular saw blade with a diameter of 105~2200mm and the bai product. It should be possible to recommend a saw blade with a reasonable structure size according to the customer's processing conditions. 2. Saw blade base selection (1) Base material and performance Diamond circular saw blade base must have sufficient strength, rigidity and hardness. Generally, the base hardness of welded saw blades requires HRC37-42; the maximum surface roughness is Ra3.2μm; surface There must be no cracks, burrs, and rust; the matrix must eliminate deformation forces and micro-cracks to ensure the balance of tensile stress, straightness and other shape and position requirements, as well as appearance and internal quality requirements. At present, the base material of diamond circular saw blades is mostly high-quality spring steel 65Mn or 50Mn2V, and the base of laser welding saw blades should be quenched and tempered steel 30CrMo, 35CrMo. Because of its low carbon content, it can be welded well with the laser welding transition layer. . (2) Base structure The base of diamond circular saw blade can be roughly divided into continuous type and nozzle type from the perspective of its peripheral structure. The continuous base is mainly used to make sintered saw blades, and the edges are mostly thinned Great Wall teeth; the nozzle-type base can be used for welding or integral sintering (the edges are also thinned Great Wall teeth). The nozzles are divided into narrow nozzles (small U-shaped, spoon-shaped) and wide nozzles (large U-shaped).

The narrow nozzle matrix is used to cut weakly abrasive or brittle materials (such as limestone, marble, microcrystalline stone, glazed tiles), and the wide nozzle matrix is used to cut large saw blades or cutting strong abrasive materials (such as sandstone, refractory) Material, concrete, asphalt pavement, etc.), which will facilitate a large amount of coolant to flow into the cut for chip flushing and cooling. The use of a narrow nozzle matrix can make the cutter heads close to each other, and at the same time, it is not as prone to deformation as a larger size trimming saw blade.
Product display
The continuity during sawing is good, the impact is not easy to form, the cut is neat, and the edge is not easy to produce The saw blade has a long service life, but the stress at the bottom of the nozzle is more concentrated, especially the small U-shaped one, which is easy to crack from here. It should be pointed out that the base body with nozzles is equivalent to extending the outer edge of the base and adding a certain stress, which can compensate for the growth of the outer edge caused by heat or centrifugal force during welding and use, so as to prevent deformation during manufacturing (integral sintering , Compensation for thermal stress or shrinkage stress of the carcass during welding) and chip removal, cooling (water-cooled and air-cooled), reduced swing and "S"-shaped cutting diameter during use; however, the water opening is likely to cause cracking and The wear is accelerated, which is mainly due to the repeated concentrated action of the force during cutting on the bottom of the nozzle (continuous stretching and compression), which is prone to fatigue cracks. Generally, increasing the arc radius of the nozzle bottom is beneficial to disperse the stress.
