What is the reason for oil leakage during CNC machining in CNC processing plants

Those who have been exposed to CNC machining should know that we are prone to oil leakage during the CNC machining process. And it is easy to see the location of oil leakage in the CNC machining center. Mainly caused by oil leakage from accessories or CNC lathe cylinder.

If it is an accessory, maintenance will be relatively simple. Leaking a cylinder can be very troublesome and may also result in the machine being scrapped. So let's analyze the reasons for CNC machining oil leakage together.

Changing the oil does not meet the standards, which often leads to oil leakage during CNC machining. The problems that occur during oil changes are mainly manifested in the following three aspects:

1、 For components with high viscosity lubricating oil, changing to low viscosity lubricating oil at will will affect the sealing performance of corresponding boxes, shaft holes, and other parts, and may greatly reduce the sealing performance of these parts.

2、 If the oil tank is not cleaned during CNC machining and oil change, the dirt in the tank may enter the lubrication system, block the oil circuit, wear the sealing components, and cause oil leakage.

3、 Excessive oil filling during CNC machining, especially in areas with rotating parts, is more prone to oil spillage due to the stirring effect of the rotating parts. Improper selection and adjustment of lubrication system components can cause CNC machining oil leakage.

 

For example, when CNC machining and maintenance personnel choose an oil pump with excessive pressure or oil output during maintenance, or when adjusting the system pressure, the pressure of the overflow valve, safety valve, pressure reducing valve, etc. is too high, and the flow rate of the CNC machine tool lubrication system is too large, which does not match the return oil system and sealing system, it can cause oil leakage.

In fact, the reasons for the oil leakage during CNC machining are not just the above points. When encountering similar problems in our actual operation, we must carefully check and promptly identify the cause of the oil leakage during CNC machining, which can also avoid unnecessary losses.
