Then it is necessary to analyze the quality problems of the belt machine. Generally speaking, there are the following points. Diamond abrasive belt, 

Vibration problem: Some belt sanders have belts attached. After turning on the machine, the machine vibrated greatly. If it is not fixed, why does it run around? Mainly because the balance of the runner is not good! The runner includes rubber wheels, guide wheels and motor pulleys. One of the three wheels has poor accuracy, poor balance, and poor machine jitter! Another reason is that the fit gap between the supporting roller parts is too large, causing relative movement and vibration between the parts. In addition, if the motor is not fixed well, it will vibrate.

Noise problem: The noise is mainly caused by insufficient rigidity of the base and supporting parts, excessive clearance of matching parts, selection of inferior bearings, and excessive speed of abrasive cloth belts.

Life issues: Some belt machines fail in a short period of time. There are several reasons: gray cast iron is used for the adjustment part, 45# carbon steel is not used for precision casting, or heat treatment is not performed, the bearing quality is not good, the lubrication is not good, the main shaft is not modulated and heat treated, or the treatment hardness is too low or too high ( Too low is easy to wear, too high is easy to break), the quality of the motor is not good.

Use problem: The size of the machine and the design of the structure are critical. A better structure and scientific size are the keys to the efficiency of polishing workers. Due to the continuous development of technology such as abrasive belt machines, the role of diamond abrasive belt polishing in the metal processing industry is irreplaceable. With advanced abrasive belt polishing equipment, it can smoothly complete metal processing tasks such as surface polishing, round polishing, trimming polishing and grinding, fillet polishing, chamfering, and deburring. Modular design can improve equipment flexibility and reduce costs.
