The reason of easy wear for saw blade

Whether it is a hard alloy saw blade, HSS saw blade, diamond saw blade at the beginning when using is strong and durable, and cutting performance is very good, but long time there will be a certain degree of wear and tear, grinding is required, dental restoration can continue to use, so what is the cause of saw blade wear of the cutting tools? It is mainly related to the following key factors.

1. Raw materials for making saw blades

In general, the harder the saw blade material is, the better the wear resistance is, but at the same time, the lower the toughness is. Hardness and toughness are opposite, the hardness of the general saw plate is about 48° to 52°, there are also higher, according to the scope of application of different materials hardness is different.

2. Alloy selection

On the choice of alloy for different cutting materials have different hardness, such as wood and aluminum alloy hardness is different, carpentry saw blade alloy hardness is higher than aluminum alloy saw blade, if the wood with metal hardness is high enough, in the process of cutting Angle of alloy due to abrasion is easy to go round, cut out will have burrs or out side damage; And the alloy of aluminum alloy if the hardness is too high, the alloy will become more brittle, no toughness, will become not sharp.

3. Surface coating

In a lot of saw blade coating is very few, only coated diamond saw blade, diamond has many advantages: high hardness, good wear resistance, low friction coefficient, but the production cost is higher, the market is still not fully mature, you can choose on the ordinary carbide saw blade coating also can improve the service life of saw blade.
