Section 2: What is the differences between Laser Cutting and Plasma Cutting ?

Working Principle:. CNC laser cutting machine is to use high power density laser beam to scan the material surface, heat the material to thousands to tens of thousands of degrees Celsius in a very short time, make the material melt or gasify, and then blow the melted or gasified material away from the cutting seam with high pressure gas, so as to achieve the purpose of cutting materials. In laser cutting, because the traditional mechanical knife is replaced by invisible light beam, the mechanical part of the laser cutting head has no contact with the work, and will not scratch the work surface in the work; The laser cutting speed is fast, the incision is smooth and smooth, generally without subsequent processing; The cutting heat affected zone is small, the sheet deformation is small, and the cutting seam is narrow (0.1 mm ~ 0.3 mm); There is no mechanical stress and shear burr in the incision; High machining accuracy, good repeatability, no damage to the material surface; NC programming, can process any plan.
CNC plasma cutting machine
is a kind of thermal cutting equipment, its working principle is to use the heat of high temperature plasma arc to make the metal partial melting at the workpiece incision, and use the momentum of high-speed plasma to eliminate the molten metal to form a cutting method.
Cutting Capabilities:Panel laser cutting machine excel at precise and intricate cuts, capable of achieving high levels of detail. It is suitable for thin to medium-thickness materials, but their efficiency decreases for thicker metals. Plasma cutting machines are better suited for cutting thicker materials, including thick metal plates, with higher cutting speeds. However, the cut quality may be comparatively lower, with wider heat-affected zones and rougher edges.
Material Compatibility: CNC Laser cutting machine can cut a wide range of materials, including metals, non-metals, and organic materials like wood and acrylic. CNC Plasma cutting machine is primarily designed for cutting conductive metals, such as steel, stainless steel, and aluminum.
Cost Considerations: Laser cutting machines generally have higher upfront costs and maintenance expenses due to the complexity of laser technology and optics involved.
Plasma cutting machines are often more cost-effective in terms of equipment and maintenance.
