What is the cause of oil leakage in cnc machining center what should be paid attention to when cnc machining workpiece?

Friends who have contacted the cnc machining center know that oil leakage will occur during the cnc machining process. In fact, the location of the oil leakage in the machining center is very simple to see. The main reason is that it is caused by accessories, perhaps the oil leakage of the CNC lathe cylinder. If it is an accessory, protection is very simple. If it is a cylinder then it is very troublesome severe will cause the machine tool to be scrapped.

1. The oil change does meet the requirements.

Often it will also cause oil leakage in cnc machining center. The problems presented in the oil change are mainly manifested in three aspects. First, regarding the selection of high-viscosity smooth oil parts, the low-viscosity smooth oil can be used at will when changing oil, which will definitely affect the corresponding box, shaft hole other sealing functions, sometimes greatly reduce the sealing of these parts. Sex. Second, if the oil tank is cleaned when the oil is changed, the dirt in the oil tank may enter the smooth system, block the oil passage, wear seals to form oil leakage. Third, the amount of refueling is too much when changing the oil, especially in the parts with rotating parts, due to the stirring effect of the rotating parts, the oil spill phenomenon is more simple.

2. Inappropriate selection conditioning of smooth system parts may cause oil leakage.

For example, cnc processing maintenance personnel chose an oil pump with too high pressure too much oil output for maintenance. Perhaps when adjusting the system pressure, the pressure of the relief valve, safety valve, pressure relief valve, etc. was adjusted too high, the flow of the CNC machine system was smooth. If it is too large does match the oil return system the sealing system, oil leakage will occur.

In fact, it is just the above points that form the cnc machining center to show oil leakage. If we encounter similar problems in the operation, we must do a good job to check the cause in time to avoid unnecessary losses. After the purchase of the machining center, do a comprehensive review to see if there are defects in the castings damage to the parts. If you need to contact the manufacturer in time. Operators should also pay attention to the following points when using cnc machining centers to process workpieces:

(1) Regarding cnc processing di one-time trial cutting process, single-stage operation form should be used for processing.

(2) When the automatic operation of the CNC milling machine starts, the rapid override feed override S are at the lowest gear, 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 appearance of the coordinates of the CNC system.

(4) Stop touching the CNC milling machine tools chips by hand. The chip must be cleaned with a brush.
