When the CNC band saw machine in the sawing process, the sawing machine control failure, may be the ac contactor core reset weak spring force is small, no longer position, can be replaced coil; Another possibility is that the sawing machine voltage is low, the iron core does not move, this time can increase the control voltage.
The CNC band saw machine in the sawing process, suddenly appear noise, may be caused by the following factors, when the band saw blade speed is too fast and the feed is too large and caused by the noise, then can reduce the band saw machine speed or feed; When the guide block of band saw machine is too tight caused by sawing noise, only need to adjust the gap of guide block; When the sawing material is too hard to cause the noise of the sawing machine, it is necessary to choose the suitable band saw blade to complete the sawing work; The last point is that the improper selection or ratio of coolant leads to the problem of band saw machine sawing, at this time, only according to the ratio of 1:10 dilution can be.
1. The saw blade held by the regulating wheel seat of the guide arm of the band saw machine is not perpendicular to the horizontal band saw table. In this case, the operator of the saw machine only needs to adjust the bolts of the regulating wheel seat of the band saw blade to make the saw blade perpendicular to the table of the saw machine; It may also be the band saw blade. The band saw blade may be loose, leading to the sawing precision error of the saw machine. It can be tightened directly.
2. When the small bearing in the regulating wheel seat of the saw machine is damaged, it will also lead to the sawing accuracy of the band saw machine, which only needs to replace the small bearing of the band saw machine.
3. The damage of the band saw blade will also lead to the saw cutting precision of the band saw machine. In the process of saw cutting, the band saw blade is a consumable, and the operator of the saw machine should check the wear degree of the band saw blade irregularly.
4. When the distance between the two guide arms of the band saw machine is too large, the sawing accuracy of the band saw machine will be inaccurate. The operator of the saw machine will adjust the distance of the guide arm of the saw machine, which is generally 6-10 cm larger than the sawing workpiece. The feed speed of band saw machine is too fast, which leads to the cutting precision of band saw machine. It only needs to adjust the speed valve of band saw machine to slow down the feed speed.
Saw machine operators in the saw cutting workpiece pay attention to avoid the above situation, but also irregular maintenance and maintenance of the band saw machine, band saw blade, so not only can improve the service life of the band saw machine, band saw blade, but also can improve the saw precision of the band saw machine.
