Machining Center Maintenance: The Precise And Efficient Way To Protect Equipment

I. Core Maintenance Principles Adhere to the principle of "prevention first, simplicity and efficiency", replacing post-event repairs with daily inspections and regular maintenance, integrating maintenance work into the production process rather than imposing additional burdens.

Ⅱ. Key Points of Phased Maintenance

(1) Daily maintenance: 5-minute basic inspection every day

Before starting up: Quickly clean the chips on the worktable, check if the lubricating oil level and air pressure are normal, test the sensitivity of the emergency stop button and protective devices, and confirm that the three-axis origin is not offset.

During operation: Pay attention to any abnormal sounds or vibrations from the main shaft and feed system. Observe the pressure stability of the hydraulic and cooling systems. If any abnormalities are detected, stop the machine immediately for inspection.

After the machine stops: Clean the accumulated chips inside the machine tool, wipe the taper holes of the main shaft and spray anti-rust oil, move the worktable to the central position, and cut off the power in the specified sequence.

(2) Regular maintenance: Precise maintenance at regular intervals

Weekly: Clean the dust on the guide rails and lead screws, replenish the lubricating grease, and check the oil level of the oil mist separator.

Monthly: Check for leaks at air pipe and oil pipe joints, tighten electrical circuit terminals, and clean the compressed air filter.

Every quarter: Check the runout accuracy of the main shaft, inspect the wear degree of the guide rails and lead screws, clean the filter screen of the cooling system, and replace the deteriorated coolant.

Every year: Professional personnel calibrate the geometric accuracy of the machine tool, replace the spare battery of the numerical control system, and inspect and replace the worn spindle bearings and motor brushes.

(3) Maintenance for Special scenarios

After heavy-load processing: Additionally, check the spindle accuracy and tool holding system, and promptly carry out accuracy compensation.

When idle for a long time: Power on and run for 1 hour every month. Apply anti-rust oil to the guide rails and main shafts, and take dust-proof and moisture-proof measures.

Ⅲ. Quick Troubleshooting of Common Faults

Loud noise from the main shaft: First, check the wear of the bearings, replace the worn parts in time and replenish the lubricating grease.

Unstable feed: Check if the servo parameters match, and tighten the transmission chain and lead screw nuts.

Abnormal tool changing action: Confirm that the air pressure meets the standard, clear the accumulated water in the cylinder, and check whether the solenoid valve circuit is normal.
