What causes oil leakage in the CNC machining center?

During the CNC processing process, there will always be some abnormal problems that we did not expect, but no matter what problems we encounter, they must be dealt with in time. Oil leakage is also common. If oil leakage occurs, it is actually very easy to detect It is easy to see which accessories leaked oil, was it due to the accessories, or the CNC lathe cylinder leaked oil. If there are accessories, repair is very simple. If it is a cylinder, it will be very troublesome and in severe cases it will cause the machine tool to be scrapped. So, let’s take a look at what causes the oil leakage accident in the CNC machining center?

1. If the oil is not changed according to regulations, it will usually cause oil leakage in the CNC processing center. There are three main problems that arise in oil replacement.

1. For parts that use high viscosity lubricating oil, if you change oil, use low viscosity lubricating oil at will, which will affect the sealing performance of the corresponding chassis, shaft holes, etc. to a certain extent. Sometimes the sealing properties of these parts will be greatly reduced.

2. If the oil tank is not cleaned when changing oil, the dirt in the oil tank may enter the lubrication system, causing oil circuit blockage, oil seal wear, and leakage.

3. The amount of oil is too large when changing oil, especially in parts where rotating parts are rotating parts. Due to the agitation of the rotating parts, oil spills are likely to occur.

2. Improper selection and adjustment of each component in the lubrication system will cause oil leakage.

For example, when CNC processing and maintenance personnel choose oil pumps with excessive pressure or excessive oil output during maintenance, or when adjusting the system pressure, the pressure adjustment of the relief valve, safety valve, pressure reducing valve, etc. is too high, and the CNC machine tool lubrication system is used to adjust the system pressure. If the flow rate is too large, such as mismatching with the oil return system and the sealing system, it will lead to oil leakage.

In fact, the oil leakage in the CNC machining center is not just the above points. If you encounter similar problems during operation, you must check and find out the cause in time to avoid unnecessary losses. After the machining center comes back from purchasing, conduct a comprehensive inspection to see if there are any casting defects or parts damage, and contact the manufacturer in time if necessary. Operators who use CNC machining center to machining workpieces should also pay attention to the following points:

1. During the first trial cutting process of cnc processing, the processing should adopt a single-stage operation mode;

2. When the CNC milling machine automatically starts working, the fast magnification and feed magnification S are at the lowest level, and then cut into the workpiece to improve efficiency;

3. When using CNC milling machine processing programs, special attention should be paid to the coordinate representation of the CNC system;

4. It is prohibited to touch the tools and chips on CNC milling machines with your hands. The chip must be cleaned with a brush.

The above points are the reasons for oil leakage in the CNC machining center . Today we will talk about it here first. If you want to know more information, please contact Dongguan Ruibang Technology to learn more.
