Metal Cutting Machine

(1) The surface of the band saw wheel is quenched and cold-worked to improve the strength of the saw wheel surface and reduce the friction between the saw wheel and the saw blade.

(2) A 3-5mm thick rubber is applied to the surface of the saw wheel to effectively reduce noise. This method is mostly used on small band saws in furniture factories.

(3) The structure of the upper saw wheel is changed from spoke type to spoke plate type to make it less susceptible to vibration. The spoke plate type upper saw wheel adopts an integral casting structure, which eliminates or reduces the airflow rotation noise and eddy current noise generated by the rotation of the spoke type upper saw wheel, and the noise of the whole machine is reduced by about 3d B(A).

In recent years, foreign countries have developed a new technology called fine plasma or high-precision plasma, which we have introduced with good results. By improving the design of the cutting moment, the quality of the cutting surface of the workpiece is significantly improved. The verticality of the edge can reach 0-1.5°, which is especially beneficial to improving the cutting quality of thick plates. Due to the improved cutting gun, the electrode life has been increased several times. However, the distance between the cutting gun and the steel plate is relatively high, which requires the height sensor on the cutting gun to respond more sensitively and the lifting response of the cutting gun to be faster.

Therefore, it is an ideal method to use plasma to cut 4-30 mm steel plates, which can avoid the shortcomings of slow oxygen-acetylene cutting speed, large deformation, serious incision engraving, and serious slag hanging. Obtained blanks of materials such as stainless steel with a certain thickness.
