CNC four axis machining will have many different situations in the process of machining. Oil leakage is a common occurrence. To solve this problem, we must find the root cause and solve the problem. The phenomenon of oil leakage during machining is also It's not surprising, so what conditions can cause oil leaks?
Oil change does not meet requirements:
Cause oil leakage in CNC machining center. The problems in the oil change are mainly manifested in three aspects.
When the oil is changed, the amount of oil is too much, especially in the parts with rotating parts, due to the stirring effect of the rotating parts, oil spills are more likely to occur.
For parts that use high-viscosity lubricating oil, changing the oil to low-viscosity lubricating oil will affect the sealing performance of the corresponding box and shaft hole to a certain extent, and sometimes greatly reduce the sealing performance of these parts.
If the oil tank is not cleaned when the oil is changed, the dirt in the oil tank may enter the lubrication system, block the oil circuit, wear the seal and cause oil leakage.
Oil leakage caused by improper selection and adjustment of lubricating system parts:
For example, when the cnc processing and maintenance personnel choose an oil pump with too high pressure or excessive oil output, or when adjusting the system pressure, the pressure adjustment of the relief valve, safety valve, pressure reducing valve, etc. is too high, and the flow rate of the CNC machine tool lubrication system is too high. If it is too large and does not match the oil return system and the sealing system, it will cause oil leakage.
Looking forward to your consultation if you have any other questions
