In the process of processing, there will always be some trouble-free problems that we did not expect, but no matter what problems we encounter, we should solve them in time, and the oil leakage is also a relatively common problem. If it is an accessory, the maintenance is very simple. If it is a cylinder then it is very troublesome and can seriously lead to machine scrapping. So below we will learn what causes oil leakage in cnc machining center?
1, oil change does not meet the requirements.
Often also cause cnc machining center oil leakage. Oil change in the problem is mainly manifested in three aspects.
One, for the use of high-viscosity lubricant parts, oil change arbitrarily changed to low-viscosity lubricant, it will make the corresponding box, shaft holes and other sealing performance is affected to a certain extent, and sometimes will greatly reduce the sealing of these parts.
Secondly, when changing oil without cleaning the oil tank, the dirt in the oil tank may enter the lubrication system, blocking the oil path, wear the seals causing oil leakage.
Third, too much oil when changing the oil, especially in the parts of the rotating parts, due to the churning effect of rotating parts, more likely to overflow phenomenon.
2, the lubrication system parts of the selection and adjustment is not appropriate and cause oil leakage.
For example, cnc machining maintenance personnel maintenance selected too high pressure or too much oil out of the oil pump, or adjust the system pressure, relief valve, safety valve, pressure reducing valve and other pressure adjustment is too high, cnc machine tool lubrication system flow is too large, etc. and return system and sealing system does not match, it will cause oil leakage.
In fact, causing cnc machining center oil leakage is not just the above points, if we encounter similar problems in the operation must do a good job of checking, find the cause in time to avoid unnecessary losses. In the machining center back after the purchase of a good comprehensive inspection to see if there are casting defects or parts damage problems, such as timely contact with the manufacturer. The operator should also pay attention to the following points when using the cnc machining center to process the workpiece.
(1) For the first trial cutting process of cnc machining, single-stage operation mode should be used for machining.
(2) When the automatic operation of CNC milling machine starts, the fast multiplier and feed multiplier S are in the lowest gear, and then the efficiency is increased after cutting into the workpiece.
(3) In the operation of CNC milling machine machining program, it is necessary to pay attention to the coordinate display of CNC system.
(4) It is forbidden to touch the CNC milling machine tools and chips with your hands. The chip must be cleaned with a brush.
