What are the main fault repairs of 3 axis cnc mill v850 that have large lubricating oil loss?
Trouble phenomenon: The lubricating oil in the centralized lubrication station is consumed a lot, and the lubricating station must be refueled every other day, and a large amount of lubricating oil is obviously mixed in the cutting fluid.
Analysis and treatment process, the vertical machining center adopts a positive displacement lubrication system. After this failure occurred, it was considered that the lubrication interval was too short, the lubrication motor started frequently, and the lubrication was too much, which caused the lubricating oil loss of the centralized lubrication station to be large. The lubricating oil loss of the bone station has been improved, but the oil loss is still large, so I focused on finding the lubrication pipeline problem. The lubrication pipeline is intact and there is no oil leakage, but it is found that the Y-axis screw nut has special lubricating oil. Unscrew it The Y-axis screw nut lubricates the metering parts, and the Y-shaped sealing ring in the metering parts is found to be damaged after inspection. After replacing the new lubricating metering parts, the vertical machining center lubricating oil failure is eliminated
