How to maintain the CNC machine tools?
CNC lathe, is a high precision, high efficiency automatic machine tool, can process linear cylinder, slash cylinder, circular arc and other complex workpiece. In order to ensure the working precision of the lathe and prolong the service life of the lathe, it is necessary to carry out reasonable maintenance.
The commonly used way of maintenance and maintenance of CNC machine tools are: pouring oil lubrication, oil splash lubrication, oil lubrication, the oil wick guide cylinder lubrication, lubrication, lubricating oil pump grease cup.
The parts in the spindle box are lubricated by the oil pump or by the spatter. The lubricating oil in the box is usually replaced once in March. There is oil window on the spindle body. If there is no oil output in the oil window, it is indicated that there is a fault in the oil pump oil delivery system. Therefore, it is necessary to stop and check the cause of the oil cut immediately, so that the lathe can be started after being repaired.
The feed box gears and bearings, in addition to the use of gear splash lubrication, oil lubrication oil groove wick guide is useful in the feed box, each class should give the oil tank with a oil. The intermediate gear shaft bearing of the exchange gear box is lubricated by the butter cup, once in every class. Bedways, slide to wipe oil gas in the before and after work.
The daily maintenance and maintenance requirements of the lathe are as follows:
First, every day after work, the power is cut off, and there are no oil stains, no iron filings, and the appearance of the lathe on the surface of the lathe, the shell, the guide rail, the screw and the light bar.
Two, every week, we need to maintain the cleaning and lubrication of the guide surface of the bed and the slideway surface of the medium skateboard. The first class maintenance is usually required when the CNC lathes are running at 500. Its maintenance work is mainly operated by the operator and carried out under the coordination of the maintenance person. Maintenance, must first cut off the power, and then according to the following order and requirements: first, the maintenance of the spindle. First, clean the oil filter, so that it has no sundries. Second, check the spindle locking nut is not loose, tighten the screw tightened. Third, adjust the clearance of brake and clutch friction plate. Secondly, the maintenance of the gear box is exchanged. First, cleaning gear, bushings, and inject new oil in the oil cup. Second, adjust the gear meshing gap. Third, check whether the axle sleeve has the phenomenon of sloshing.
Three, the maintenance of the skateboard and the knife rack.
Four, the maintenance of the tail seat (wiping the surface and lubricating oil).
Five, the maintenance of the lubrication system. First, clean the cooling pump and the oil filter. Secondly, to ensure the smooth flow of oil. Third, check the oil, maintain good (oil standard clear)
Six, the maintenance of electrical appliances. First, clean the dust on the electric motor and the electric box. Secondly, the electrical apparatus is fixed and tidy.
Seven, the appearance of maintenance. First, clean the surface and shell of the CNC lathe, keep it inside and outside, clean, no rust, no oil. Secondly, check and complement each screw and handle. After cleaning and cleaning, the components are lubricated.
It is worth noting that the power supply must be cut off in the maintenance of the machine and then the maintenance is carried out by the steps.
