There are many conditions because there was no note the details in the use of H.S.S for various types of pipe cutting. 1)Material.Sometimes the problem is to be in the cutting materials,due to there are too many impurities in the materials we buy,so when saw encountered these impurities particles,superhard saw blade may be broken or made a great sound,and the surface may not smooth.If we use more soft HSS saw will not break, but will skew, because the blade will change direction when contact particle.

2)Saw blade.Saw will compression deformation not put properly, serrated blunt did not grind, the worse side of the pendulum,choice of improper teeth count, saw blade strength is not correct, choose the wrong saw, saw low quality.

3) Cutting Machine.Fixture of the state, saw containing incorrect, the number of rotary is not correct, not to cut off the pace, cutting oil choice, and saw blade and cut off due to machine error will affect one another. Some customers complained the results of cutting skew, we went to the scene by the observation,personnel transport materials not a fixed feed-in,factory’s workers often careless collision distortion out. Feeding wood was cut-out distortion, of course, all materials must be out of the distortion. Customers have complained frequently break-circular saw can not be solved, we found a spot on the mechanical design has been pointed out that in the longer cutting material, must be subject to Taiwan to make the cut was not shaking paragraph. However, customers still want to cut same small materials, so there will be sloshing saw the wood was broken. Customers also have the machines installed at the level of correction, so the machine distortion radically.

4)Use the copy machine.Most of the cost is in the machinery,low plant price prove that use of cheaper,so there is no guarantee of quality.Therefore, improper or shaking caused by it is not enough mechanical stability of the collision.

5)Manual machines(operator).As for the manual machine work by hand, may also be breakdown saw caused by operators sometimes under the knife too much force or too fast.

Use saw blade must be pay attentions to these followings.

1)Must determine cut wood has indeed been fixed to.
