Oil leakage in CNC加工 centers can cause equipment damage, 運用上のダウンタイム, そして維持費が高くなる. 迅速な検出, proper oil change practices, and correct selection of lubrication system components are essential to maintain precision and reliability.
Key Fault Types in CNC Machining Oil Leakage
| Fault Type | Description | Impact |
|---|---|---|
| Improper Oil Change | Not following the oil change schedule or using wrong lubricant | Oil leaks, wear, equipment damage |
| Improper Component Selection | Incorrect selection or adjustment of lubrication components | Seals damaged, oil overflow, mismatched flow |
| Excessive or Insufficient Oil | Overfilling or underfilling | Reduced sealing performance, potential system malfunction |
1. Failure to Change the Oil According to Regulations
Failure to change the oil according to regulations often leads to oil leaks in CNC machining centers. There are three main areas of concern when changing oil:
- If a component uses high-viscosity lubricant, arbitrarily switching to a low-viscosity lubricant can affect the sealing performance of the corresponding housing, shaft bore, and other components, sometimes significantly reducing the sealing performance of these areas.
- Failure to clean the oil tank during oil changes can allow contaminants inside to enter the lubrication system, causing blockages in the oil lines, wear of oil seals, and leaks.
- Excessive oil volume during oil changes, especially in areas with rotating parts, can easily cause oil overflow due to the agitation created by these rotating parts.
2. Improper Selection and Adjustment of Lubrication System Components
Improper selection and adjustment of lubrication system components can also cause oil leaks.
例えば, CNC machine maintenance personnel may:
- Select an oil pump with excessive pressure or output.
- Over-adjust the pressure of relief valves, safety valves, and pressure reducing valves when adjusting the system pressure.
- Over-adjust the flow rate of the CNC machine’s lubrication system, resulting in mismatches with the oil return system and sealing system.
Other Causes and Preventive Measures
実際には, there are more reasons for oil leaks in CNC machining centers than just the above. If you encounter similar problems during operation, be sure to thoroughly inspect and identify the cause promptly to avoid unnecessary losses.
After purchasing the machining center, conduct a thorough inspection to check for casting defects or damaged parts. Contact the manufacturer immediately if necessary.
Operator Notes for CNC Machining Centers
Operators using CNC machining centers should also note the following:
- During the first trial cut, use single-stage operation.
- When the CNC milling machine automatically begins operation, set the rapid override and feed rate (S) to their lowest setting, and then cut into the workpiece to improve efficiency.
- When using a CNC milling machine program, pay special attention to the coordinate representation of the CNC system.
- Avoid touching tools and chips on the CNC milling machine. Chips must be cleaned with a brush.
