Laser cutting machine cold water machine alarm solution
Laser cutting machine chiller alarm is a common fault that needs emergency treatment, which is directly related to laser life and cutting quality. The following is a systematic troubleshooting process and solution, which is executed in priority order: Emergency treatment steps (stop response with...Read more -
How to address overheating of the cutting head nozzle
The laser‑cutting‑head nozzle overheats, which can degrade cut quality—resulting in slag adhesion and a rough kerf—and shorten the nozzle’s service life, potentially even damaging the more expensive focusing lens. Below, we will provide you with a systematic troubleshooting and resolution guide, ...Read more -
How to resolve delamination issues when cutting aluminum sheets
Delamination after aluminum‑sheet cutting is typically not caused by a single factor, but rather by the combined effects of the material, tooling, equipment, and process parameters. Below, we will provide a systematic troubleshooting and resolution guide, covering both root cause analysis and pro...Read more -
How the air pressure affects the cutting section
Air pressure is one of the key parameters that affect the quality of cutting (especially the quality of cutting sections). Its impact is not a single “high good” or “low good”, but an “optimal range” that needs to be precisely matched with parameters such as cu...Read more -
The Relationship Between Laser Cutting Focus and Burrs
The focal position in laser cutting has a direct and deterministic relationship with burr formation. In short, the focal position directly affects the energy distribution of the beam within the material, thereby determining the kerf quality, the efficiency of molten-material expulsion, and whethe...Read more -
Selection of Positive/Negative Focus During Laser Cutting
When laser cutting, the choice between positive defocus (positive focus) and negative defocus (negative focus) primarily depends on the material type, plate thickness, and process requirements. Below is a clear, straightforward decision-making guide. Core Principles In-focus (zero defocus): Energ...Read more -
How to achieve a bright, polished edge when laser cutting steel plates?
To achieve an oxide-free, highly reflective cut surface (known as “bright-face cutting”) when laser cutting steel plates (typically carbon steel), the key is to completely prevent oxidation during the cutting process and to use finely tuned cutting parameters that thoroughly blow away the molten ...Read more -
Problems that may occur when laser cutting plates
In laser cutting, there are problems such as scum at the bottom of the workpiece, folds at the lower end of the cutting surface, over-burning of right angles/sharp corners, and rough cutting surface. The following will systematically sort out the causes and solutions of these problems. Overview o...Read more -
How to solve the problem of burrs in laser cutting of thin plates
The appearance of burrs in laser cutting of thin plates is a very common issue. This is usually not caused by a single factor but is the result of the combined effect of multiple factors such as equipment, parameters, materials, and gases. To systematically solve this problem, we can follow a tro...Read more -
Laser cutting machine does not produce light, how to check
The fiber laser cutting machine does not emit light and requires systematic, safe and efficient investigation. Please strictly abide by the safety regulations, and be sure to operate after the equipment is completely powered off and the capacitor has been discharged, especially when checking the ...Read more -
What is the reason for sticking slag and blocking the nozzle during laser cutting?
It is a common problem to block the nozzle with slag when laser cutting, which is usually caused by a combination of many factors. The following are the main reasons and systematic analysis: Core reason analysis 1. Auxiliary gas problem Insufficient air pressure: The gas pressure is not enough t...Read more -
When to choose negative focus for laser cutting
The “negative focus” (also known as “lower focus” or “focus inside the plate”) of the laser cutting machine is the 1 important process to adjust the laser focus position. In simple terms, negative focus refers to setting the focus of the laser below the surface...Read more
