The difference between plasma and laser cutting

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.

1. With the development of plasma cutting, the working gas that can be used has obvious influence on the cutting characteristics, cutting quality and speed of plasma arc. Argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases are commonly used in plasma arc, of which air is the main gas source.

Plasma cutting machine is widely used in automobile, locomotive, pressure vessel, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structure and other industries!

2. Laser cutting 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.

General: in terms of cutting accuracy, the plasma and laser can reach 0.5mm and 0.2mm respectively; In terms of cost, plasma cutting machine is much cheaper than laser cutting machine, the cost is about the same, the power ratio is 20:1, the difference is huge, customers can decide to buy the required products according to your cutting needs, the right product is the best.
