1. Oil change does not meet the requirements.

It often causes oil leakage at the center of CNC processing manufacturers. The problems that occur in oil change are mainly manifested in three aspects. First, for parts with high-viscosity lubricating oil, if you change the oil to a low-viscosity lubricating oil, the sealing performance of the corresponding box and shaft hole will be affected to some extent, and the sealing of these parts will be greatly reduced. . Second, when the oil is changed, the fuel tank is not cleaned, and the dirt in the fuel tank may enter the lubrication system, block the oil passage, and wear the seal to cause oil leakage. Third, when the oil is changed, the amount of oil is too much, especially in the parts with rotating parts, due to the stirring action of the rotating parts, the oil spill phenomenon is more likely to occur.

2. The selection and adjustment of the lubrication system parts are not suitable and cause oil leakage.

For example, when cnc processing and maintenance personnel use oil pumps with excessive pressure or excessive oil output, or when adjusting system pressure, the pressure regulation of relief valve, safety valve, pressure reducing valve, etc. is too high, and the flow rate of CNC machine tool lubrication system If it is too large and does not match the oil return system and the sealing system, it will cause oil leakage.

In fact, the oil leakage situation in the cnc machining center is not only the above points. If we encounter similar problems in operation, we must check it and find out the cause in time to avoid unnecessary losses. After the purchase center returns, do a comprehensive inspection to see if there are any casting defects or parts damage. If you need to contact the manufacturer in time. The following points should also be noted when the operator uses the cnc machining center to machine the workpiece:

(1) For the first trial cutting process of Kunshan CNC processing factory, it should be processed in single-stage operation mode.

(2) When the automatic operation of the CNC milling machine starts, the rapid override and the feedrate override S are at the lowest gear position, and then the efficiency is improved after cutting into the workpiece.

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

(4) It is forbidden to touch the CNC milling machine tools and chips by hand. The chip must be cleaned with a brush.
