On Site Maintenance And Upkeep Of CNC Lathes

Lubrication, maintenance, reasonable use, and standardized handover system are the main contents of CNC lathe management. The technical and professional quality of CNC lathe operators, as well as the quality of lubrication, are important factors affecting the frequency of faults.

Train CNC lathe operators to systematically learn the principles, performance, lubrication parts, and methods of the machine tool, laying a foundation for better use of the machine tool. At the same time, a series of practical and effective measures should be formulated in the use and management of CNC lathes. Make the responsibility clear to the operator themselves and directly linked to economic interests. For each accident that occurs, the equipment supervisor shall organize equipment personnel, maintenance personnel, technical backbone, etc. to conduct accident analysis, determine the main and non main responsible parties, and arrange for post accident maintenance work to ensure that it does not affect the normal production progress. Criticize and educate the responsible person, and impose certain economic penalties in accordance with the compensation method for abnormal damage to production materials in the factory. Of course, economic punishment is not the purpose, but mainly to arouse the responsible party's high attention to the accident and prevent them from making the same mistake again. Accidents or operational errors are not scary, the key is how to learn from failures.

Emphasizing the handover procedures and strengthening the daily maintenance of equipment is another important aspect of CNC lathe management. Operators are required to check the shift handover record before starting work every day, then check for any abnormalities, observe whether the automatic lubrication oil tank of the equipment is running low, and then manually add oil several times. Under normal circumstances, after a few seconds, lubricating oil should flow out of the guide rails of the machine tool. Then, manually inject oil into the oil holes of other components and accessories of the CNC lathe, especially the piston type components connected to the center of the hydraulic chuck and the pull rod. If not used for a long time and not maintained, it is likely that the clamping stroke cannot be adjusted. Cutting tools, threaded holes, and water holes are prone to accumulate some iron filings, which can stick together in just a few days and be quite difficult to clean. When mixed with cutting fluid, these things are prone to oxidation and corrosion. If these miscellaneous items are cleaned up every day, it will save a lot of trouble. Especially when the cutting table of the equipment is lifted when rotating, and then reversed to clamp and fall when in place, it is easy to get the iron shavings that have not been cleaned in time stuck inside, causing the cutting table to be unable to clamp or not in the correct position. Equipment with alarm feedback function will sound an alarm. However, a considerable portion of CNC equipment does not have this function. Even if the cutting table is not in place, it will still follow the instruction program to process the workpiece. Mild cases can cause the workpiece to be scrapped, while severe cases may result in the cutting table hitting the workpiece or chuck.

In summary, the management, maintenance, and lubrication of equipment are directly related to the immediate interests of operators and the production progress in the factory. So for the management of CNC lathes, we should start from small things and start from small ones. Operators need to take careful care of the equipment in order to receive generous rewards.
