1. Daily machine walk-around
Before startup, check the work area, guards, doors, visible cables and hoses for damage or obstruction. Confirm emergency stops and interlocks are intact; never bypass a safety device.
2. Daily gas and status check
Check the gas type and supply condition against the approved process chart. Review machine and laser status indicators and record unusual alarms instead of repeatedly resetting them.
3. Daily cooling-system check
Check the chiller display, visible coolant level if the manual provides one, and accessible hoses for leaks or alarms. Use only the specified coolant and service procedure.
4. End-of-shift cleaning
Remove loose scrap and dust from operator-accessible areas using the machine maker’s method. Isolate the machine as required and keep cleaning tools away from optics, sensors and moving mechanisms.
5. Weekly mechanical inspection
Inspect accessible covers, fixtures and cable carriers for looseness, debris or visible damage. Lubrication points and intervals differ by machine; use the lubrication chart rather than applying oil by guesswork.
6. Check the cutting nozzle and ceramic parts
With the machine in the required safe state, inspect the nozzle, ceramic ring and their seating for wear, cracks or contamination. Replace only with compatible parts and follow the head manufacturer’s procedure.
7. Protect optical components
Keep the protective window and other optics in the condition specified by the head maker. Do not open the cutting head or touch a lens unless trained and authorized; a qualified technician should diagnose suspected contamination or damage.
8. Clean optics only by the approved method
Use the exact cleaning materials and method specified by the component manufacturer. Do not use household tissue, compressed air or an unapproved solvent, and stop if the window is damaged or contaminated inside the assembly.
9. Schedule laser-source service
Follow the laser-source maker’s inspection and service intervals. Do not open the source enclosure or perform internal maintenance unless authorized personnel and the documented procedure allow it.
10. Maintain the chiller
Check alarms, filters and coolant condition according to the chiller manual. Isolate power before user-level service and have leaks, abnormal temperature behavior or repeated alarms assessed by service personnel.
11. Maintain compressor and air dryer
Drain, inspect and replace filters only according to their manuals and the site’s air-quality requirements. Depressurize safely before service; have pressure vessels and electrical components handled by qualified personnel.
12. Keep a maintenance log
Record date, operating hours if available, checks, replaced consumables, alarms and service actions. Use the records to plan preventive service and provide technicians with useful history.
