CNC laser cutting is a numerical control processing technology that achieves cutting by melting or vaporizing materials with a high-energy-density laser beam. Its core features include non-contact processing, narrow cutting seams (0.1-0.3mm), and a small heat-affected zone. It is mainly applied in the precision processing of metal and non-metal plates. The following are the key technical points and application details:
Workflow
The movement trajectory of the laser head is programmed and controlled by the numerical control system. The laser beam is focused on the material surface through the lens, and the cutting is completed by blowing away the slag with gas.
Supports three-dimensional cutting, with a photoelectric conversion efficiency of up to 25% (fiber laser).
Cutting method:
Oxidation cutting : oxygen-assisted combustion, suitable for carbon steel.
Melt cutting : nitrogen protected, suitable for stainless steel, aluminum alloy.
Oblique cutting technology : By driving the pipe to move axially through a roller, complex Angle cutting is achieved (patented technology of Hefei Siwei).
Note :
The cutting speed can reach 40m/min for standard equipment or 48m/min for precision models.
The floating control device adopts ultrasonic three-dimensional distance measurement to achieve a dynamic spacing accuracy of 0.2mm.
Core Advantage
Efficient production : Multi-axis linkage supports continuous operation (such as exchange worktable
design).
Intelligentization :
The cloud database automatically matches process parameters.
Adaptive compensation for deformation of stamped parts by capacitive sensors.
Environmental friendliness : The dust purification and cooling circulation system reduces pollution.
Application Fields
Automobile manufacturing : aluminum alloy cutting of power battery brackets (nitrogen pressure 0.8MPa, pulse frequency 2000Hz is the optimal parameter).
Mechanical engineering : It has both mass production and process testing functions, supporting the comparison and optimization of 600 sets of parameters.
Emerging demand : The pipe processing industry promotes the development of dual-station equipment (to reduce maintenance workload).
The technological evolution focuses on the research and development of multi-axis control and high-power laser heads to meet the processing requirements of super-large workpieces and complex structures.
CNC laser cutting is a precision processing technology based on high-energy-density laser beams. It precisely controls the movement trajectory of the laser head through a computer numerical control system to achieve melting or vaporization cutting of materials.
Its main features include:
High precision and smooth cut
Fast cutting speed and high efficiency
Wide applicability and flexibility
Small heat-affected zone, good environmental friendliness
However, this technology has limitations: it has restrictions on the thickness of the material (usually suitable for thinner plates), and special processing is required when cutting high-reflectivity metals such as copper and gold.
