1, cost. The cost of the diamond belt is 3-4 times that of the tungsten band when many tungsten band saws are capable.
2, bad use environment: the diamond belt welding is placed in the bearing metal, by electronic welding. The tungsten belt is welded through copper. Tungsten belt can tolerate incorrect band saw speed, inappropriate coolant, poor condition saw machine, poor technology operator, incorrect feed force. Diamond belt saws are easily damaged and repair costs are high.
3, emery belt saw blade is easy to drop sand, especially the higher working temperature when cutting, the easier sand fall; Tungsten band saw blade will not drop sand, making the cutting more stable and flat, longer service life.

4, The cutting range of diamond band saw blade is limited by its own material. -I'm sorry. -I'm sorry. -I'm sorry. -I'm sorry. -I'm sorry. -I'm sorry. Wait a minute; The application range of tungsten band saw blade, besides the application range of diamond saw blade, can cut a lot of diamond saw blade, such as cutting titanium alloy, quenching tool steel, alumina(sapphire) and so on.

5, Due to the limitations of the sawing body, the cutting advantage of Silicon is not obvious or even immeasurable.
6. The smoothness of the cutting surface is not different from that of the tungsten band saw blade if the strip does not drop sand. The smoothness of the cutting surface can not be compared with that of the tungsten band saw blade.

7, The production of diamond belt saw blade is highly polluting. The production of tungsten band saw blade is quite different from that of emery.
8. Because of its limitations, the diamond band saw blade can only be cut and welded for sand plating production on the basis of the length of the customer's saw blade when the order comes in, and can not be sand plated in advance and then welded on the basis of the customer's requirements(since the temperature at the time of welding is sufficient to soften the diamond drop), which is highly restraint; Tungsten belt saw blade can be smelted directly in the production line in the factory saw belt, dealers buy plates with ready goods, when the customer needs to cut directly according to the specific length of welding back, do not worry about the sand will soften the problem of falling. This can make delivery faster, service more considerate, more able to meet the needs of customers.
