How to extend the service life of medium and large turning centers?

Medium and large turning centers are core equipment in the manufacturing industry. They have high purchase costs and complex maintenance. Through scientific maintenance management and standardized operation, their service life can be significantly extended and the operating costs of enterprises can be reduced. The following are key measures to improve equipment durability:

1. Strictly implement daily maintenance procedures

(1) Lubrication system management

Regularly replace or replenish guide rail oil and spindle lubricating oil to ensure that all moving parts are fully lubricated (it is recommended to perform according to the cycle specified in the equipment manual).

Use the original manufacturer's specified model lubricating oil to avoid wear caused by oil incompatibility.

 

(2) Cleaning and rust prevention

Clean cutting residues and coolant residues every day to prevent iron chips from accumulating and causing scratches on the guide rails or lead screws.

When the shutdown exceeds 24 hours, apply anti-rust oil to the exposed metal parts.

 

(3) Inspection of key components

Check the wear of the spindle bearings, lead screws, and guide rails every month, and adjust the gap or replace accessories in time.

Regularly calibrate the hydraulic system pressure to avoid overloading of transmission components due to abnormal pressure.

 

2. Standardize operation to avoid human damage

(1) Rationalize processing parameters

Avoid long-term overload operation, especially the spindle speed and feed rate must strictly match the workpiece material requirements.

When using high-hardness materials, give priority to staged processing to reduce the instantaneous load of the equipment.

(2) Matching of fixtures

Ensure that the fixture is rigid enough to avoid vibration caused by unstable clamping, which will lead to a decrease in the accuracy of the spindle or guide rail.

Regularly check the positioning accuracy of the fixture to prevent additional wear of the equipment due to offset.

(3) Emergency handling of abnormal conditions

If abnormal noise, overheating or vibration occurs during processing, stop the machine immediately for investigation and prohibit forced operation.

Equip with vibration monitors or temperature sensors to achieve early warning of faults.

3. Optimize the equipment operating environment

(1) Temperature and humidity control

The workshop temperature is maintained at 20℃±2℃ and the humidity is less than 70% to prevent electrical components from getting damp or metal parts from expanding and contracting due to heat and shrinking.

Install air conditioners or dehumidifiers to avoid environmental fluctuations affecting equipment accuracy.

(2) Foundation and vibration reduction measures

The equipment must be installed on an independent concrete foundation (thickness ≥ 300mm) to isolate external vibration interference.

Vibration reduction trenches are set around heavy equipment to reduce the risk of resonance.

 

4. Systematic maintenance and upgrade

(1) Software and firmware updates

Update the CNC system program regularly to repair potential control logic defects and improve operational stability.

Back up key parameters (such as pitch compensation and tool setting data) to avoid data loss caused by system crashes.

 

(2) Professional maintenance team support

Original engineers perform in-depth maintenance every year to detect hidden faults (such as aging of servo motor insulation).

Operators need to receive periodic training to master the latest maintenance technology.

 

5. Spare parts management strategy

(1) Original accessories first

Key components (such as spindle bearings and encoders) must use original certified products to avoid compatibility issues.

Establish an inventory list of wearing parts (such as seals and belts) to shorten downtime.

 

(2) Recycling of old parts

Professionally repair the replaced guide rails and lead screws for non-high-precision processing scenarios to reduce maintenance costs.

The key to extending the life of the turning center lies in preventive maintenance and standardized operation. By establishing equipment health records, implementing a spot inspection system, and combining intelligent monitoring methods, more than 70% of sudden failures can be reduced. Equipment management is not a simple cost expenditure, but a long-term investment to ensure production efficiency and process stability.
