What is the reason of oil leakage in CNC machining center and what should be paid attention to in CNC machining?

Friends who have come into contact with CNC machining centers know that there may be oil leakage during the CNC machining process. In fact, it is easy to see the location of the oil leakage in the machining center. The main reason is that it is caused by accessories, perhaps due to oil leakage from the cylinder of the CNC lathe. If it's an accessory, protection is very simple. If it is a cylinder and it is troublesome, it will cause the machine tool to be scrapped.

1. The oil change does not meet the requirements.

Often, t can also cause oil leakage in CNC machining centers. The problems presented during oil change mainly manifest in three aspects. Firstly, regarding the selection of components with high viscosity smooth oil, changing the oil to low viscosity smooth oil at will will inevitably affect the sealing function 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 smooth system, block the oil circuit, wear the sealing components, and form 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, the phenomenon of oil overflow is simpler.

2. Improper selection and conditioning of smooth system components can cause oil leakage.

For example, when CNC machining and maintenance personnel repair, they choose an oil pump with excessive pressure or oil output. Perhaps 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 smooth system of CNC machine tools is too large, which does not match the return oil system and sealing system, resulting in oil leakage.

In fact, the occurrence of oil leakage in CNC machining centers is not limited to the above points. If we encounter similar problems during operation, we must take a good look and promptly identify the reasons to avoid unnecessary losses. After purchasing from the processing center, conduct a comprehensive inspection to see if there are any casting defects or component damage issues. If there are any, please contact the manufacturer in a timely manner. When operators use CNC machining centers to process workpieces, they should also pay attention to the following points:

(1) Regarding the one-time trial cutting process of CNC machining, a single stage operation form should be selected for machining.

(2) When the automatic operation of the CNC milling machine starts, the fast rate and feed rate S are in the low gear of zui, and then the efficiency is improved after cutting into the workpiece.

(3) In the operation of CNC milling machine processing programs, it is necessary to pay attention to the coordinate display of the CNC system.

(4) Prevent manual contact with CNC milling machine tools and chips. The chip must be cleaned with a brush.
