reasons caused by the problem of second-hand metal band sawing machine
1. The metal band saw machine is affected by the vibration of the surrounding punching equipment, and the fixing bolts of the band saw machine are loosened, which affects the jitter of the saw frame, and the band saw blade is affected by the vibration force during the cutting process, resulting in tooth chipping.
2. Air entering the lifting cylinder, or due to poor oil quality, cylinder wear, control valve out of control, etc., all cause the saw frame to fail to drop at a constant speed, and the teeth may be broken.
3. The three-point linearity of the driving wheel, the driven wheel and the guide escapement can not reach the accuracy, the saw band cannot run in a straight line, and there may be unstable cutting left or right and up and down.
4. The motor belt is damaged for a long time and appears aging and slack. It may lose rotation intermittently during operation, causing the saw band to experience intermittent and weak sudden stop during cutting, resulting in tooth chipping.
5. The guide block of the sawing machine wears out after a long time use, which may cause the saw band to not be able to cut normally during the cutting process, causing unexpected bad factors to cause the saw band to be damaged and scrapped.
