First of all, the failure analysis of aluminum cutting machine problems:
1. Vibration problem: Some aluminum cutting machines are hung with abrasive belts. After starting the machine, the machine vibrates a lot. If it is not fixed, it will "run around"! What is the reason? The main reason is that the balance of the rotating wheel is not good! The rotating wheel has a rubber wheel, a guide wheel, and a motor pulley. One of the three rotating wheels has poor accuracy, poor balance, and poor machine jitter! Another reason is that the fitting clearance of the parts of the support wheel is too large, causing relative movement between the parts and vibration. Then, the motor is not fixed, and it also vibrates.
2. Noise problem: The noise is mainly due to insufficient rigidity of the base and supporting parts, and excessive clearance of matching parts (some factories have poor and backward processing equipment, coupled with poor quality awareness, the manufactured parts are very bad, and there is almost no matching tolerance requirements!), the selection of inferior bearings, the speed of the abrasive belt is too fast, etc.
3. Life problems: some aluminum cutting machines are broken after a short 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 carried out, the bearing quality is not good, and the lubrication Not good, the spindle has not undergone modulation heat treatment, or the hardness of the treatment is too low or too high (too low and easy to wear, too high to break), and the motor quality is not good.
4. Problems in use: the size and structure of the machine are very important. Better structure and scientific size are the key to the efficiency of polishing workers.
