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 […]

Introduction Edge defects are the most common problems in daily laser cutting production. Rough edges, longitudinal stripes, edge burning, burrs and oxidation discoloration often lead to rework, low yield and increased post-polishing workload. Most edge quality issues are not caused by machine failure. They come from incorrect parameters, poor gas stability, worn accessories and improper […]

Introduction Material waste is one of the biggest invisible losses in metal processing. Many laser cutting workshops face high scrap rates and low material utilization, which directly reduce profit margins. Most cutting scraps are not caused by machine failure, but by unreasonable nesting, improper operation and material management problems. This article shares practical methods to […]
