How to Solve Capacitance‑Value Alarm in Laser Cutting

Capacitance‑value alarm is a frequent failure for fiber laser cutters. The capacitive sensor acts as the “eyes” of the cutting head. It maintains constant focal height by detecting capacitance variation between cutting head and metal plate. An alarm will trigger when detected capacitance deviates... Read More

Why Laser‑cut Circles Are Out‑of‑Round and Troubleshooting

Cut circles turning elliptical, polygonal or distorted is a common laser‑cutting issue. It stems from combined factors of machinery, cutting process and material. Below lists major causes and countermeasures. Mechanical & Transmission System Problems (Most Probable Root Cause) 1. Clearance or... Read More

Breaking Through the Bottleneck of Air & Nitrogen Cutting Efficiency — New Piercing Process Revealed

Air or nitrogen cutting often faces low piercing efficiency, which directly affects overall processing speed and the service life of nozzles and consumables. Main Causes of Low Piercing Efficiency for Air/Nitrogen Cutting Insufficient energy density. The purity of compressed air contains around ... Read More

How to Adjust Piercing Parameters for Thick Plate Cutting

Piercing thick plates is a critical process in laser cutting. Improper parameters may result in nozzle damage, lens contamination, poor cutting quality or failure to penetrate the plate. The core idea for thick plate piercing is taking a gradual and gentle approach. Input energy moderately and al... Read More

Why Do Laser Cutting Machines With Identical Specs Vary In Price? 4 Key Hidden Details

Even laser cutting machines with identical power ratings, worktables, and control systems can have vastly different quoted prices. Many sheet metal fabrication companies base their decisions solely on spec-sheet comparisons, opting for low-cost equipment—only to later contend with frequent breakd... Read More

Three Major High-Frequency Quality Failures in Laser Cutting丨Quickly identify and resolve finished-product defects.

In laser cutting production, defects in finished products are the primary issue that most severely impacts on-time delivery and drives down the first-pass yield. In many cases, recurring minor malfunctions are not caused by hardware failure but rather by issues with parameters, components, or deb... Read More

Laser Cutting Machine Consumables Maintenance Guide

Business owners in sheet metal and hardware processing know all too well: the biggest hidden cost of a laser cutting machine is never the electricity bill—it’s the high‑frequency consumables. Many companies focus solely on the power of the equipment itself, as well as hardware components like cut... Read More

Comprehensive Guide to the Complete Elimination of Laser-Cutting Burrs and Slag Adherents! 90% of factories have fallen into these pitfalls.

Laser‑cutting operators are almost invariably plagued by burrs and slag adhesion. After cutting, the workpiece exhibits rough edges and slag adhesion at the bottom, which not only necessitates additional grinding and rework, slowing down production, but also results in material waste, non‑conform...
