The difference and comparison of laser cutting, water cutting, plasma cutting, and wire cutting

Laser cutting is the use of a focused high-power density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the irradiated material. At the same time, the molten material is blown away by the high-speed airflow coaxial with the beam to realize the cutting of the workpiece. open. CO2 pulsed lasers are generally used now, and laser cutting is one of the thermal cutting methods.(CO2 Laser Engraving Cutting Machine Wholesales)

The difference and comparison of laser cutting, water cutting, plasma cutting, and wire cutting

Water cutting: also known as waterjet, that is, high-pressure water jet cutting technology, is a machine that uses high-pressure water to cut. Under the control of the computer, the workpiece can be carved at will, and the material quality is less affected. Water cutting is divided into two methods: no sand cutting and sand cutting.

Plasma arc cutting: It is a processing method that uses the heat of the high temperature plasma arc to locally melt (and evaporate) the metal at the incision of the workpiece, and use the momentum of the high-speed plasma to remove the molten metal to form the incision.

Wire cutting: Wire electric discharge machine (WEDM for short), which belongs to the category of electrical machining, and sometimes called wire cutting. Wire cutting can be divided into fast wire cutting, medium wire cutting, and slow wire cutting.

The wire speed of fast wire EDM wire cutting is 6-12m/s, and the electrode wire moves back and forth at high speed, so the cutting accuracy is poor.

Middle wire EDM is a new technology developed in recent years to realize the function of frequency conversion multiple cutting on the basis of fast wire wire cutting.

The wire speed of slow wire EDM wire cutting is 0.2m/s, and the electrode wire moves in one direction at a low speed, so the cutting accuracy is very high.

Application range comparison:

The laser cutting machine has a wide range of applications. Regardless of metal or non-metal, you can cut and cut non-metal, such as cloth, leather, etc. You can use CO2 laser cutting machine, and cutting metal can use fiber laser cutting machine. The plate deformation is small.(CO2 Laser Mirror Wholesales)

Water cutting is cold cutting, no thermal deformation, good quality of the cutting surface, no secondary processing, and easy secondary processing if necessary. Water cutting can punch and cut any material, with fast cutting speed and flexible processing size.

Plasma cutting machine can be used for cutting various metal materials such as stainless steel, aluminum, copper, cast iron, carbon steel, etc. Plasma cutting has obvious thermal effect, low precision, and it is not easy to perform secondary processing on the cut surface.

Wire cutting can only cut conductive materials, and cutting coolant is required during the cutting process, so materials that are not conductive, afraid of water, or afraid of contamination by cutting coolant, such as paper and leather, cannot be cut.
