Maintenance of laser cutting machines
Most failures announce themselves: dirty optics, rising coolant temperature, wear on turbo blower or vacuum pump. Regular maintenance catches these signs before production stops.
Maintenance scope
- Condition check
- Structured inspection of laser source, optics, mechanics, electrics and cooling against a checklist.
- Optics
- Checking and cleaning protective windows and lenses, mirror alignment and beam path on CO2 machines.
- CO2 assemblies
- Oil change and overhaul of turbo blower and vacuum pump.
- Cooling
- Water quality (conductivity, pH), filters, flow and temperature control of the chiller.
- Assist gas
- Pressure control and nozzle centring.
How often to maintain
The interval depends on operating hours, material and environment. A quarterly or six-monthly inspection has proven itself for many machines; on CO2 machines the manufacturer's intervals for turbo blower oil and vacuum pump filters also set the pace.
Refurbish rather than buy new
Many wear parts of CO2 machines can be overhauled instead of replaced – turbo blowers, vacuum pumps and adaptive optics. This can reduce maintenance costs considerably; we quantify the saving in the quote for your machine. More under remanufacturing.
