The chiller cools the laser source and cutting head. Overheating will trigger alarms, reduce laser output stability and even damage the laser.   Common Symptoms High temperature alarm pops up Unstable water temperature fluctuation Low water flow warning Water leakage   Possible Causes Dust clogging on condenser Insufficient or contaminated circulating water Water filter blocked […]

Burrs are the unwanted metal residues attached to the edge of laser cut workpieces. It increases secondary polishing workload and affects product quality.   Common Symptoms Hard metal slag sticks to the bottom of cutting edge Rough, uneven cutting surface Burrs appear intermittently during cutting   Possible Causes Incorrect gas pressure or gas purity Cutting […]

Height following system keeps consistent distance between nozzle and sheet. If it fails, you will get bad cuts, nozzle collision and machine damage.   Common Symptoms Nozzle hits the metal plate Unstable cutting height during processing Height reading jumps randomly Alarm triggered when starting cutting   Possible Causes Dust, spatter or residue on the capacitive […]

The laser cutting head is the core component of your fiber laser machine. Proper daily maintenance avoids sudden downtime and reduces costly part replacement.     Daily Check Inspect the protective lens for dust, oil stains or scratches. Replace immediately if damaged. Check the nozzle for deformation, clogging or residue buildup. Clean or swap nozzles […]

High‑reflective materials such as copper, brass, and aluminum are always challenging for fiber laser cutters. Strong reflected laser light may bounce back toward the laser source, which could potentially damage your laser generator.     Main risks of high‑reflective material cutting Back‑reflected laser energy returns to the laser head and resonator. Unstable cutting results: rough […]
