What is CNC plasma cutting?

What is CNC plasma cutting?

CNC plasma cutting refers to the cutting of metals using a plasma torch controlled from a computer. Plasma cutters operate by forcing a gas or compressed air at high speeds through a nozzle. Once an electric arc is introduced to the gas, ionized gas or plasma is created, the fourth state of matter.

How much does a plasma CNC cutter cost?

$15,000 to $300,000
Depending on type, size, and features, a CNC plasma cutting machine could range anywhere from $15,000 to $300,000. That’s a big range, but the vast majority of CNC plasma machines sold today are well below the $100,000 mark.

What can a CNC plasma cutter cut?

CNC plasma cutters can cut through a wide range of different materials, including steel, aluminum, brass, and copper, and can be used for a selection of different industries like fabrication and welding shops, auto repair and restoration shops, industrial construction sites, and salvage operation sites.

What is plasma cutting process?

Plasma cutting (plasma arc cutting) is a melting process in which a jet of ionised gas at temperatures above 20,000°C is used to melt and expel material from the cut. During the process, an electric arc is struck between an electrode (cathode) and the workpiece (anode).

What materials can you plasma cut?

What Can a Plasma Cutter Cut Through?

  • Mild steel.
  • Stainless steel.
  • Carbon steel.
  • Expanded steel.
  • Aluminum.
  • Copper.
  • Brass.
  • Other ferrous (iron-containing) and non-ferrous materials.

Can CNC plasma cut wood?

Plastics and wood are not electrically conductive and cannot be plasma cut. However, you can use a rotary saw, router, or other tool if you want to cut these materials in the PlasmaCAM machine. The accuracy of the machine is better than that of the plasma cutter.

How accurate are CNC plasma tables?

High quality CNC cutting machines deliver accuracy far tighter than the plasma arc and oxy-fuel processes. Generally, the expected accuracy for the high definition plasma cutting process is approximately +/- . 040” (material thickness dependent) and +/- . 125” for oxy-fuel cutting of heavy plate.

What are the advantages of plasma cutting?


  • Able to cut all conductive materials.
  • Great quality for thickness up to 50 mm.
  • Maximum thickness up to 150 mm.
  • Comparatively cheap for medium thickness cuts.
  • Best way to cut medium thickness stainless steel and aluminium.
  • CNC machines are available to provide high precision and repeatability.

What gas is used for plasma cutting?

Argon gas is used when plasma marking (a whole other subject). A mixture of Argon and Hydrogen is often used when cutting thicker Stainless Steel or Aluminum. Some people use a mixture of Hydrogen and Nitrogen, or Methane and Nitrogen when cutting thinner Stainless Steel.

How do you charge for plasma cutting?

Re: Pricing structure for plasma cutting I charge by the square inch of the piece I cut, plus any welding, painting or assembly at $50/hour.

Is plasma cutting expensive?

The initial investment in plasma machines is often more expensive than other cutting methods. A typical hand-held plasma cutting unit will cost about $1,500 to $3,500, and replacing plasma tips and electrodes costs about $15 to $20 per set.

¿Qué es una cortadora de plasma?

La Cortadora de Plasma CNC plasma, sirve para hacer cortes en metales, especialmente eficaz a la hora de trabajar con diferentes tipos de acero.

¿Cuándo se inventó la cortadora plasma?

El uso de cortadoras plasma comenzó en los años 50 y desde ese momento, estas máquinas han ido evolucionando, convirtiéndose en equipos más potentes, precisos y fiables.

¿Qué son las máquinas de corte con plasma?

Este tipo de máquinas de corte con plasma, son compatibles con elementos como el acero, acero inoxidable, bronce, aluminio y aleaciones, titanio, hierro y otros metales no ferrosos. Su espacio de trabajo es amplio, por lo que se puede trabajar sobre piezas de gran tamaño. En cuanto a grosor, su espesor de corte es de hasta una pulgada.
