The maintenance and care of precision machining components should be preventative and systematic to ensure equipment precision and production continuity. The key lies in daily inspections, periodic calibrations, and tiered maintenance, with collaborative prevention and control efforts from operators to the technical team to minimize unplanned downtime and machining deviations.
Daily Maintenance (Required Every Day)
Performed by operators, this is the first line of defense for ensuring stable equipment operation:
Cleaning and Protection: Before and after operation, use a lint-free cloth with a dedicated cleaning agent (such as isopropyl alcohol) to clean the guide rails, spindle taper holes, and fixture positioning surfaces to prevent residual chips and oil from causing wear or corrosion.
Special Note: High-precision equipment such as ceramic engraving and milling machines require special attention to dust removal to prevent intrusion into moving parts.
Lubrication Management: Strictly adhere to the oil types and lubrication cycles specified in the equipment manual. For example, use 7008 high-speed grease for the spindle bearings, lubricate the guide rails once per shift, and record in the "Lubrication Log." Check if the oil pressure is normal (usually 0.2–0.4 MPa). If a "low oil pressure alarm" is detected, immediately check for pipe blockage or pump malfunction.
Inspection and Troubleshooting
Perform a "five-sense inspection" before and after each shift:
Look: Check instrument displays and for oil leaks.
Listen: Check for abnormal noises during spindle operation.
Touch: Check for abnormal overheating of the motor and bearings.
Smell: Check for any burning smell.
Measure: Use a dial indicator to check the spindle radial runout (standard ≤0.002 mm). If any abnormality is found, immediately stop the machine and report it, attaching parameter records and on-site photos.
