The chuck is the terminal of the entire chuck control system, and its function is to clamp the workpiece to complete the processing. Due to the complexity of the working conditions, it is necessary to maintain and maintain the chuck. During its normal operation, grease should be injected regularly to reduce the wear of the indexing shaft and the ejector rod. In addition, it is necessary to clean up the iron filings on the chuck and fixture in time to ensure the machining accuracy.
1. Chuck lubrication: daily
(1) Use a lubricating gun to inject about 2ml of grease into the grease nipple on the front of the chuck, and pay attention to prevent overfilling the grease;
(2) The frequency of grease filling is once per shift, and the grease used in the chuck is lithium-based general-purpose grease or lithium-based extreme pressure grease;
(3) Clean the fixture once per shift.
2. Chuck cleaning: monthly
(1) Remove the clamp, disassemble the inner liner, and take out the sealing ring, roller bearing and plane bearing in turn;
(2) Clean the roller bearings and plane bearings with a cleaning fluid (such as clean gasoline), and wipe the seal ring with a clean cloth;
(3) After applying grease evenly on the rollers and flat bearings, install the flat bearings, needle roller bearings, seal rings and molds back to the clamping end cylinder according to the order of disassembly.
