Oil Replacement.
: Replace oil in the vacuum pump and Roots pump.
Sealing.
: Tighten all plugs to ensure Roots pump airtightness.
Gas Diverter.
: Clean the white plastic plug at the Roots pump’s gas diverter and apply a thin layer of silicone-free high-vacuum grease.
9. Chiller Maintenance.
Regular chiller maintenance ensures effective cooling and prevents system failures.
Clean Heat Sinks.
: Brush and blow dust from heat sinks, using a specialized cleaner if needed.
Clean Condenser.
: Remove dust from the condenser.
Check Water Level.
: Top up with pure or deionized water if the level is low.
Inspect Electrical Terminals.
: Clean and check terminals for dust (with power off).
Check Water System.
: Inspect for leaks or aging pipes and replace components as needed.
Monitor Water Quality.
: Replace cooling water if it becomes cloudy or contaminated.
Clean Filter.
: Remove debris from the filter core and replace damaged cores with manufacturer-approved parts.
10. Air Compressor Maintenance.
Maintain the air compressor to ensure a reliable gas supply.
Drain Water.
: Drain the storage tank 3–8 times daily and fully drain after shutdown.
Clean Air Filter.
: Clean the air filter every two weeks, or more frequently in harsh environments.
Replace Filter Core.
: Replace the filter core every 1,200 hours and inspect all components.
Lubricate Bearings.
: Add grease to oil-free compressor bearings every 1,000 hours.
Refer to Manual.
: Follow the manufacturer’s maintenance guidelines.
11. Refrigerated Air Dryer Maintenance.
Keep the air dryer in good condition to prevent moisture-related issues.
: Drain 3–8 times daily and fully drain after shutdown.
: Clean the filter core monthly.
Clean Condenser Fins.
: Dust and clean condenser fins monthly.
: Replace the air filter core every six months.
12. Voltage Stabilizer Maintenance
Maintain the voltage stabilizer to protect electrical components.
Tighten Terminals
: After one month of use, retighten all terminals with the main power off.
Clean Components.
: Every three months, check carbon brush tension and remove carbon powder and dust with dry compressed air.
A consistent maintenance routine is the key to maximizing the performance and longevity of your laser cutting machine. By following the daily, weekly, and periodic tasks outlined in this guide, you can prevent costly repairs, improve cutting precision, and ensure a safe working environment. Schedule maintenance tasks, train staff, and consult your machine’s manual for specific requirements to keep your equipment running smoothly.

Press brake maintenance and repair should be viewed as an ongoing process rather than a reaction to failure. Proper lubrication, careful hydraulic system management, and regular mechanical inspection form the foundation of reliable machine operation. These practices not only reduce downtime but also help maintain consistent bending accuracy over the machine’s service life.
A consistent maintenance routine is the key to maximizing the performance and longevity of your laser cutting machine.
