How to choose and buy good abrasive belt machine

That want to analyze the belt machine quality problems, generally have the following points

1, vibration problem: some belt sanding machine hang sanding belt, after starting the machine, the machine vibration is very big, not fixed words will run around what reason?The balance that basically is rotating wheel is bad!Rotating wheel has rubber wheel, guide wheel, motor pulley, three rotating wheels have a good precision, balance is not good, machine jitter is not good!Another reason is that the supporting wheel parts with the gap is too large, causing the relative motion between the parts, the vibration.Then the motor is not fixed well, also produce vibration.

2. Noise problem: the noise is mainly due to the insufficient rigidity of the base and the supporting parts, the excessive clearance of the matching parts, the selection of low-quality bearings, the excessive speed of the emery cloth belt and other reasons.

3, life problem: some sand machine in not how long it is broken, because there are a few points: adjust part adopts grey cast iron, no use 45 # carbon steel precision casting, or without heat treatment, bearing quality is bad, bad lubrication, spindle without modulation heat treatment, or treatment of hard through low or too high (high low easy wear and easy to fracture), motor quality is bad.

4, the use of the problem: the size of the machine, the design of the structure is critical, better structure and scientific size is the key to the efficiency of the polishing workers.Due to the continuous development of strip polishing technology, strip polishing plays an irreplaceable role in metal processing industry.With advanced belt polishing equipment, metal processing tasks such as surface polishing, circular polishing, finishing and grinding, radius polishing, chamfering and deburring can be successfully completed.Modular design is adopted, which can improve the flexibility of the equipment and reduce the cost.
