1, the cost. When many tungsten band saws are competent, the cost of the diamond belt is 3-4 times that of the tungsten belt.

　　2, bad use of the environment: Diamond belt welding is to place the diamond in the bearing metal, made by electronic welding. Tungsten sand belts are brazed. Tungsten abrasive belts can tolerate incorrect sawing speeds, improper coolant, poorly-conditioned sawing machines, poorly-operated operatives, and inaccurate feed forces. Diamond band saws are easily damaged and repairs are expensive.

　　3. The diamond band saw blade is easy to get out of sand, especially the higher the working temperature when cutting, the easier the sand falls; and the tungsten band saw blade will not drop sand, so that the cutting is more stable and flat, and the service life is longer.

　　4, The cutting range of the diamond band saw blade is limited by its own material, such as most of the metal can not be cut, the material with extremely high hardness is not cut well, etc.; and the tungsten band saw blade The scope of application in addition to the scope of application of the diamond saw blade, can also cut a lot of diamond saw blade can not be completed or complete the bad cutting work, such as cutting titanium alloy, quenching tool steel, alumina (sapphire) and so on.

　　5, because of the limited design of self-saw belt body, the diamond band saw blade is not obvious or even powerless for the cutting of similar large-section silicon body. Tungsten band saw blade can be used to perform such cutting tasks.

　　6. If the diamond band saw blade does not fall sand, there is no difference in the flatness of the cutting surface compared with the tungsten band saw blade; if the sand starts to fall, the flatness of the cutting surface will be different from that of the tungsten band saw blade. , And with the serious situation of sand falling, more and more no comparable.

　　7. The production of corundum band saw blades is very polluting, and most domestic manufacturers use the loopholes of supervision to steal acid during the production process. The environment, especially the water environment, is very polluted. The production of tungsten abrasive band saw blades And completely different from the corundum, there is no problem of environmental pollution.

　　8. Because of its limitation, the diamond band saw blade can only be sawn according to the customer's saw blade length, and can be produced by welding and sand coating. It cannot be pre-plated and then cut according to customer requirements (because the temperature during welding is sufficient) The emery can be softened and dropped. This is very restrictive. The Tungsten Band Saw Blade can directly smelt the tungsten sand on the production line to the sawing belt at the factory. The dealers purchase the tapes for stocking. After cutting and welding and tempering, there is no fear that the sand will soften and drop. This can make the delivery faster, the service more thoughtful, and it can meet the needs of customers.
