What is the reason for the oil leakage in the CNC machining center?
In the process of CNC machining, there will always be some abnormal problems that we did not expect, but no matter what problems are encountered, they must be dealt with in time. Oil leakage is also relatively common. If there is oil leakage , In fact, it is easy to find, it is easy to see which accessory leaks oil, whether it is due to the accessories, or the cylinder of the CNC lathe leaking oil. If the accessories are available, the maintenance is very simple. If it is a cylinder, it will be very troublesome, and in severe cases, the machine tool will be scrapped. So, let's take a look at what caused the oil leakage accident in the CNC machining center?
First, if the oil is not changed according to the regulations, it will usually lead to oil leakage of the CNC machining center. There are three main problems in the oil replacement.
1. For parts that use high-viscosity lubricating oil, use low-viscosity lubricating oil at will when changing the oil, which will affect the sealing performance of the corresponding chassis, shaft holes, etc. Sex is greatly reduced.
2. If the oil tank is not cleaned when the oil is changed, the dirt in the oil tank may enter the lubrication system, causing blockage of the oil circuit, wear of the oil seal, and leakage.
3. When the oil is changed, the amount of refueling is too large, especially in the parts with rotating parts, due to the stirring effect of the rotating parts, oil spills are prone to occur.
Second, improper selection and adjustment of various components in the lubrication system, resulting in oil leakage.
For example, cnc processing and maintenance personnel choose an oil pump with excessive pressure or excessive oil output during maintenance, or when adjusting the system pressure, the pressure adjustment of relief valve, safety valve, pressure reducing valve, etc. If it is too high, the flow rate of the CNC machine tool lubrication system is too large and the oil return system and sealing system do not match, which will lead to oil leakage.
In fact, it is not only the above points that cause oil leakage in the CNC machining center. If you encounter similar problems in operation, you must do a good job of inspection and find out the reasons in time to avoid unnecessary loss. When the machining center is purchased back, do a comprehensive inspection to see if there are casting defects or damaged parts, and contact the manufacturer in time if necessary. Operators who use cnc machining centers to process workpieces should also pay attention to the following points:
1. During the first trial cutting process of cnc machining, the machining should adopt the single-stage operation mode;
2. When the CNC milling machine starts to work automatically, the rapid override and feed override S are in the lowest gear, and then cut into the workpiece to improve efficiency;
3. When using the CNC milling machine to process programs, special attention should be paid to CNC Coordinate representation of the system;
4. It is forbidden to touch the tools and chips on the CNC milling machine by hand. Chips must be cleaned with a brush.
The above points are the reasons for the oil leakage of the CNC machining center. Today we will talk about it here first. If you want to know more information, welcome to come to Science and Technology Learn more.
