Common Problems and Solutions of Woodworking Band Saw Machine

The common faults in the sawing of woodworking band sawing machine are the cracking of the saw blade, the movement and the twists and turns of the sawn wood. When the woodworking band saw machine is running, if the saw blade jumps and is accompanied by abnormal phenomena such as crushing sound, the saw blade may have cracks and should be stopped immediately for inspection. What are the usual failures?


1. The bearing or spindle is worn and should be replaced.

2. The tensioning equipment fails, the weight is too heavy, and the saw blade is used for too long each time. Check the tensioning equipment, lighten the lifting weight and replace it.saw blade(The use time of the saw blade shall not exceed 2 hours at a time)

3. The edge surface of the saw wheel is too large before and after the diameter of the saw wheel is worn. The flange surface shall be trimmed (adjusting the inclination of the upper and lower saw wheels can be postponed)

4. The upper and lower saw wheels are twisted and not in the same plane. The upper and lower saw wheels should be adjusted.

5. The steel of the saw blade is brittle and the tolerance is small; the saw blade is too thick. The saw blade shall be replaced.

6. The joint is not firmly welded or damaged near the joint. The saw blade shall be welded from scratch and trimmed. (Welding equipment best choice of my company's saw blade welding machine)

7. If the sawtooth is not sharp or the feed is too fast, the saw blade should be ground in time.

8. When the saw passes through small, clamp saw and saw blade generate heat, and the degree of tension is reduced or even disappeared. Replace the saw blade with moderate saw path, remove resin, saw foam and sundries on the saw wheel and saw blade, and brush lubricating oil frequently.
