What is the difference of iron CNC plasma and fiber laser cutting machines

CNC plasma cutting machines and CNC fiber laser cutting machines are used to cut metal materials. CNC plasma cutting machines is a new type of thermal cutting equipment, the working principle is to use the heat of high temperature plasma arc to make the metal part of the workpiece incision melting, and the use of high-speed plasma momentum to exclude molten metal to form a cut method.

With the development of CNC plasma cutting machines, the working gas has obvious influence on the cutting characteristics, cutting quality and speed of plasma arc. The common plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.

CNC plasma cutting machines is widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, steel structure and other industries!

Fiber laser cutting is scanned surface by using CNC fiber laser cutting machines beam with high power density, in a very short period of time will be heating the material to thousands and tens of thousands of degrees Celsius, the material melting or vaporization, and high pressure gas to melting or vaporization of material from the slit blow away, to cut the material for the purpose of. Fiber laser cutting is not visible due to beam instead of the traditional mechanical knife, the mechanical part of laser scalpel and work without contact, not at work to scratch the surface; CNC fiber laser cutting machines cutting speed, smooth incision, generally without the need for subsequent processing; cutting heat affected zone is small, the plate deformation is small. Narrow kerf (0.1mm~0.3mm); incision without mechanical stress, shear free burr; high machining accuracy, good repeatability, no damage to the material surface; NC programming and machining of arbitrary planar graphs, the whole plate large format cutting, no need to open mold, time saving.

On the cutting precision, CNC plasma cutting machines is less than 1mm, CNC fiber laser cutting machines can reach less than 0.2mm; the cost of plasma cutter is cheaper than more, in the machining precision plasma cutting relative to the laser cutting is a rough machining, a fine machining!
