1. Do a good job of lubrication to ensure that the lathe chuck has good precision after long-term use. However, improper or improper lubrication will cause some problems, such as abnormal function at low pressure, weak clamping force, poor clamping accuracy, abnormal wear and jam, so the chuck must be properly lubricated.
2, at least once a day, molybdenum disulfide grease (black color), the grease into the chuck nozzle until the grease overflows the jaw surface or the inner hole of the chuck (the inner hole protection sleeve and the joint nut). If the chuck is rotated high or a large amount of water-based cutting oil is used in processing, more lubrication is required, which must be determined according to different situations.
3. After working on the chuck, be sure to clean the chuck body and the slide surface with a wind gun or similar tool.
4. Remove the chuck and clean it every 6 months (keep the sliding surface of the jaws clean) and lubricate it. If the cast iron is cleaned at least once or twice every 2 months, check the parts for cracks and wear (new parts are replaced immediately). After the inspection is completed, the oil must be fully supplied to form.
5. For different workpieces, use different clamping methods or make special fixtures. (Three-jaw chucks only use a type of cockroaches, and use it to clip irregular or strange workpieces, which will cause damage to the chuck.) If the chuck pressure is not normal, the chuck will be under high pressure, or the machine The chuck will also clamp the workpiece after the machine is turned off, which will reduce the life of the chuck! Therefore, when the chuck gap is found to be too large, the new chuck must be replaced immediately.
6, the use of anti-rust effect cutting oil, can prevent the inside of the chuck rust, because the rust of the chuck will reduce the clamping force, and can not clamp the workpiece.
