How to maintain the chuck of laser pipe cutting machine?

1. Do a good job of lubrication to ensure that the chuck still has good precision after long-term use. But incorrect or inappropriate lubrication will lead to some problems, such as pneumatic chuck not working properly at low air pressure, weakened clamping force, poor clamping accuracy, abnormal wear and sticking, so the chuck must be properly lubricated.

2. Use molybdenum disulfide grease (black in color), pour the grease into the nozzle of the chuck until the grease overflows the surface of the jaws or the inner hole of the chuck. If the chuck is used for long-term high-speed rotation, or a large amount of oxygen is used for processing, more lubrication is required, and the frequency of lubrication must be increased according to the specific situation.
3. After the processing is completed, the chuck must be cleaned with a high-pressure air gun or similar tools to clean the chuck body and slideway surface. It is recommended to remove the chuck jaws for cleaning every 6 months (keep the sliding surface of the jaws clean) and lubricate them. Check all parts for cracks and wear, and replace severely worn parts immediately. After the inspection, it is necessary to brush sufficient lubricating oil on the sliding surface of the jaws before assembly and use.
4. For different workpieces, use different clamping methods or make special fixtures. The standard laser pipe cutting chuck is suitable for symmetrical and closed tube shapes. If you forcefully use it to clamp irregular or strange workpieces, it will cause chuck abnormalities; if the air supply pressure of the chuck is too high, the chuck will be under high pressure or after shutdown The chuck also clamps the workpiece, which will reduce the life of the chuck and cause problems such as excessive chuck clearance.
5. Anti-rust is another important point, because the rust of the chuck will reduce the clamping force, so that the workpiece cannot be clamped.
