How to prevent faults in small CNC machining centers?

I. Environmental and Installation Requirements

Environmental control ‌ : Maintain the workshop temperature between 0 and 35℃, humidity below 75%, and keep away from vibration sources and direct sunlight.

Power supply stability ‌ : Ensure that the voltage fluctuation is within ±10%. It is recommended to use a dedicated power line or install a voltage stabilizer.

Ⅱ. Standardized Operation and Programming

Operating procedures ‌ : Operate strictly in accordance with the manual and avoid arbitrarily modifying system parameters.

Programming safety ‌ : Before processing, verify the origin of the program coordinates and the tool change point, and set the cutting parameters (such as rotational speed and feed rate) reasonably.

Ⅲ. Regular maintenance and upkeep

Daily cleaning ‌ : Clean the chips and dust on the guide rails and worktable every day.

Regularly check ‌ :

Daily ‌ : Check lubrication, coolant and air pressure.

Monthly ‌ : conduct a comprehensive inspection of the electrical, hydraulic and cooling systems.

Annual ‌ : Precision calibration and component replacement are carried out by professionals.

Iv. Spare Parts Management and Preventive Measures

Key spare parts ‌ : Stock up on vulnerable parts such as spindle bearings, servo motors, precision guides, and tool magazine units.

Preventive maintenance ‌ : Regularly clean the hydraulic oil tank filter, check the system battery and desiccant.

V. Key Points for Fault Prevention

Spindle maintenance ‌ : Regularly inspect bearing wear and spindle accuracy.

Feed system optimization ‌ : Adjust the preload of the lead screw nut pair to eliminate transmission clearance.

Automatic tool changer (ATC) ‌ : Check the coupling of the tool magazine, the clamping pin of the manipulator and the sealing of the pneumatic system.

Auxiliary system maintenance ‌ : Regularly clean the cooling water pump and inspect the chip removal device.

Ⅵ. Long-term shutdown maintenance

Thorough cleaning ‌ : Remove internal chips and oil stains.

Lubrication and rust prevention ‌ : after full-stroke lubrication of each shaft, apply anti-rust oil.

Parameter backup ‌ : Back up the parameters and program data of the numerical control system.

Power and gas cut-off ‌ : turn off the main power supply and gas source.

Ⅶ. Environment and Safety

Working environment ‌ : Keep the workshop clean and dry, and avoid dust and corrosive gases.

Safety operation ‌ : Before maintenance, cut off the power supply, hang a tag and lock it. Operators should wear protective equipment.

Prompt ‌ : Establish an equipment file to record each maintenance and fault handling for easy status tracking.
