Because the machine tool serves as the master machine in the machining production process and plays an important role in the machining process, Metal 3D Printing is essential that any damage to the machine tool be avoided during the machining and production processes. When operating the machine tool, the operator will frequently run into the problem of oil leaking out of it. Then, what do you believe to be the causes of the oil spill? The following is a synopsis of the various factors that contributed to the oil spill.

Leaking, dripping, and oil flow are the three primary kinds of oil leakage that can occur in machinery during the production of mechanical goods. When one drop of oil is applied once every half hour in the portion of the bonding surface that is static, or when one drop of oil is dropped once every six minutes in the portion of the bonding surface that is moving, this is an example of the so-called leakage. Dripping refers to the process in which a single drop of oil is applied to each of the moving and static joints every two to three minutes. In the event that more than five drops of oil fall per minute, this indicates that oil is flowing.

Incorrect maintenance is the root cause of the machine tool's oil leakage the vast majority of the time. Let's perform an in-depth analysis of the situation.

1. The necessary components or assembly do not fulfill the requirements

This circumstance is the most common factor that contributes to oil leaking from machines. For instance, if O-rings are not used correctly during maintenance, there is a good chance that oil will leak out. Multiple members of the maintenance staff came to the conclusion that the machine's oil leakage was caused by the deformation or damage to the O-ring. In most cases, they will replace the seal with one that has dimensions and contours very similar to the original. At this time, they are ignoring an important problem, which is the problem with the O-ring's pressure resistance. This provides the maintenance personnel with the incorrect idea, given that the lubrication pressure of most machine tools is less than three megapascals. If they are the same size and have the same specifications, O-rings can be replaced. It is possible to use this circumstance without risk in the event that the pressure is low; however, if it is subjected to a high pressure of 5 MPa, there will be issues with oil leakage.

2. Oil change does not meet the requirements

This predicament is frequently one of the factors that contribute to oil leaking from machine tools. When getting an oil change, the three most common issues are as follows:

First, if you do not understand the viscosity of the parts, use low-viscosity lubricants for parts that use high-viscosity lubricants. If you use high-viscosity lubricants for parts that use low-viscosity lubricants, the sealing of the corresponding box body and axle hole will be affected to some extent, and it may even reduce the sealing of these parts, which will result in oil leakage.

Second, when the oil is changed, the fuel tank is not cleaned. The dirt that is in the oil tank may enter the lubrication system, which may result in oil blockage and seal wear, both of which may result in oil leakage.

Third, there is an excessive amount of oil in the oil change. This is especially problematic in the areas that contain rotating parts because the stirring action of the rotating parts makes it more likely that oil will spill.

3. The improper selection and adjustment of various components of the lubrication system

When the maintenance is carried out, for instance, the oil pump that has either a very high pressure or a large oil output will be chosen. When the system pressure is adjusted, the pressure of the relief valve, the safety valve, and the pressure reducing valve are all adjusted to be too high. Additionally, the flow rate of the lubrication system of the machine tool is adjusted to be too high. It is possible for there to be oil leakage if the sealing system does not match.
