steel circular saw blades

In the use of high-speed hacksaw for cutting all kinds of pipes, there are many situations because there is no attention to detail caused.
1, Material: sometimes the  bandsaw blades problem is with the material to be cut, because there are too many materials purchased impurities, so when the blade hit these impurities particles, super-hard blade may break or give great sound, cut out The surface will be uneven. But with softer HSS saw blade can not break, but the results will be skewed cutting phenomenon, because the blade when in contact with particles shift phenomenon.
2, the blade: blade did not properly gracefully compressive deformation, serrated blunt out no grinding, yaw rate deviation, number of teeth inappropriate choice of saw blade strength is not correct, choose the wrong blade, blade quality is poor.
3, cutting machine: state of the fixture, the blade filled with incorrect rotation number is not correct, not cutting speed, cutting oil selection, and the saw blade and cutting machine error may be due to influence each other. When guests complain about cutting results skewed to the site via our observations, feeding rack not fixed, the plant personnel to transport material, often careless collision crooked away, was cut off crooked timber feeding rack after, of course, must be cut out of material crooked. Customer complaints are also often broken saw blade can not be solved, we got to the scene found the book of mechanical design has been pointed out that the longer the cutting material, must have been cut by Taiwan to make the segments are not shaking. However, the customer still and chopped material as well, so the blade will have to be cut by shaking timber crashed. There is also the customer's machine is not in the installed horizontally correction, so the wet polishing pad  machine was fundamentally crooked.
4, the use of counterfeit machine: Because most of the cost of the machine in the mechanical materials, machine parts cheap that the use of cheap, of course, there is no guarantee of quality. Therefore, there may be insufficient because of mechanical stability undue impact or shaking.
5, manual machine (operator): Since the machine is manually operated manually, sometimes the operator under the knife under the knife too hard or too fast, it may cause blade breakage.
Blade must be used note the following:
One must determine the cut material has indeed fixed.
2, according to the stone drill bits  material to be cut off condition set.
3, filled with saw, must be part of the jig clean out debris, and then pay attention to the direction of rotation, the blade is firmly seated.
4, at the beginning and stop cutting cutting, do not feed too fast, it may cause broken teeth and damaged.
5, full use of cutting oil (I hope with Workpiece selection cutting oil).
6, Disposable circular saw blade circular saw blade cutting machines and cutting machines generally different, we must choose the correct blade, can not be mixed.
