What causes oil leakage in cnc machining centers?

In the process of processing, there will always be some trouble-free problems that we did not expect, but no matter what problems are encountered, we must solve them in time. Oil leakage is also a relatively common problem. The condition of the oil is actually very easy to find, and it is easy to see which part it is because it is caused by the part or the oil leakage of the CNC lathe cylinder. In the case of accessories, maintenance is very simple. If it is a cylinder then it is troublesome and will seriously cause the machine to be scrapped. Then let's find out what causes the cnc machining center to leak oil?

Precision parts processing
1. The oil change does not meet the requirements.
Oil leakage from cnc machining centers is often caused. The problems in oil change are mainly manifested in three aspects.
First, for components using high-viscosity lubricating oil, changing to low-viscosity lubricating oil at will when changing oil will affect the sealing performance of corresponding boxes and shaft holes to a certain extent, and sometimes greatly reduce the sealing performance of these parts. .
Second, if the oil tank is not cleaned during oil change, the dirt in the oil tank may enter the lubrication system, block the oil passage, wear the seals and cause oil leakage.
Third, too much oil is added during oil change, especially in the parts with rotating parts. Because of the stirring action of the rotating parts, oil spill is more likely to occur.
2. Inappropriate selection and adjustment of lubrication system parts caused oil leakage.
For example, cnc machining and maintenance personnel use oil pumps with too high pressure or excessive oil output during maintenance, or when the system pressure is adjusted, the pressure of the relief valve, safety valve, pressure reducing valve, etc. is too high, and the flow rate of the CNC machine tool lubrication system If it is too large and does not match the oil return system and the sealing system, it will cause oil leakage.
In fact, it is not just the above points that cause the oil leakage situation of cnc machining center. If we encounter similar problems in operation, we must do a good job of checking and find the cause in time to avoid unnecessary losses. After the purchase of the machining center, do a comprehensive inspection to see if there are any casting defects or parts damage. If necessary, contact the manufacturer in time. The operator should also pay attention to the following points when using the CNC machining center to process the workpiece:
Precision parts processing
(1) For the first trial cutting process of cnc processing, single-stage operation mode should be used for processing.
(2) When the automatic operation of the CNC milling machine starts, the fast override and feed override S are at the lowest position, and then the efficiency is improved after cutting into the workpiece.
(3) In the operation of the CNC milling machine processing program, it is necessary to pay attention to the coordinate display of the CNC system.
(4) Do not touch the CNC milling machine tools and chips with your hands. The chip must be cleaned with a brush.
