Band sawing machine is more and more widely used because of its high cutting precision and efficiency, high material utilization and wide application range. In order to ensure the cutting accuracy of the machine tool, the band saw blade is deflected by 45 ° in principle, so that the tension of the saw blade on its width is different, so that the edge has enough rigidity, and the middle position still has certain toughness, so that the saw blade is not easy to break. Band sawing machine The deflection of the saw blade is realized by the guide device of the machine tool components. The guide device always restricts and controls the position and direction of the saw blade in the cutting process of the saw blade. The alloy steel is used to improve the wear resistance of the guide opening of the guide device.

It is very important to determine the position of the guide device. Although there are no clear regulations and requirements in the certificate of machine tool and the manufacturing and acceptance technology of machine tool, whether the band saw blade can run according to the ideal position and reduce the bending and alternating stress to a low limit can not only ensure the cutting accuracy of the machine tool, but also prolong the service life of the band saw blade. The installation and alignment of guide device is the key, which should be paid attention to and guaranteed in machine tool assembly.

In the process of using the band saw machine, the guiding device also plays an important role. The accuracy of the sawing material, the smoothness of the cutting surface and the speed of the sawing material all play a great role in the guiding device of the sawing machine. Let's share the effect of the guiding device of the band sawing machine for you. During the sawing process of the band saw blade, the saw frame has a downward force. Under the influence of this force, the saw blade will deviate to both sides when sawing the workpiece, and the guide block is to guide the saw blade forward, and the two will be subject to force friction. After a long time, the guide block will be worn, and the wear loss of the guide block on the side close to the workpiece will be greater. Due to the large wear difference force, the distance between the guide blocks can be properly adjusted after the wear deviation It can remove the guide block and smooth the plane. From the above points, it is not difficult to see that the saw guide device is actually very important. Users who often operate the sawing machine should always check the wear condition of the guide block of the sawing machine. If the guide block is seriously worn, a new guide block should be replaced to prevent the workpiece from being worn out and causing unnecessary loss.

Now the cutting materials are widely used in the industry after band sawing machine. However, emulsion cooling is mostly used for the smoothness of sawing machine nowadays, and many of them are poured between raw materials and saw blade to achieve smooth and cooling effect. Although the operation is simple, the smooth liquid used here needs a set of sound and reliable filtering system, which virtually increases the cost of band sawing machine processing itself Moreover, the emulsion used for a long time needs to be treated with environmental protection, and the production cost increases year by year.

With the increase of national environmental protection policy implementation, saw machine users also feel that the reform of saw blade smoothing method is imminent. If the smooth method can not be changed, not only the production cost is increasing, but also the environmental protection cost is a large part. In order to better maintain the sawing machine, extend the life of the saw blade, and reduce the damage and replacement frequency of the saw blade, it is necessary to select a more advanced smoothing method. The oil and gas smoothing technology is particularly suitable for use on the sawing machine, which not only saves the filtering equipment required for the sawing machine itself, but also saves space. In addition, the use of oil and gas smoothing method, the consumption of smooth oil is very low, there is no waste, so there is no need for the post-treatment of the smoothing agent. Band sawing machine can bring good economic and environmental benefits for enterprises, which is a good choice for sawing machine processing enterprises.
