Causes of oil leakage in CNC machining centers

2023-09-09      362

Changing oil that does not meet the requirements often leads to oil leakage in the center of CNC machining manufacturers. The problems that occur during oil changes are mainly manifested in three aspects. Firstly, for components that use high viscosity lubricating oil, changing the oil to low viscosity lubricating oil at will will affect the sealing performance of the corresponding box, shaft hole, and other parts, and sometimes greatly reduce the sealing performance of these parts. Secondly, if the oil tank is not cleaned during oil change, the dirt in the tank may enter the lubrication system, block the oil circuit, wear the sealing components, and cause oil leakage. Thirdly, when changing the oil, the amount of oil added is too much, especially in areas with rotating parts. Due to the stirring effect of the rotating parts, oil overflow is more likely to occur.

 

Improper selection and adjustment of lubrication system components can cause 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 adjusted 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.

 

Actually, there are more than just these causes of oil leakage in CNC machining centers. If we encounter similar problems during operation, we must conduct inspections and promptly identify the causes to avoid unnecessary losses. After purchasing from the processing center, conduct a comprehensive inspection to see if there are any casting defects or damaged parts. If there are any, please contact the manufacturer in a timely manner.
