What is a CNC Plasma Cutter?

A CNC plasma cutter is a tool to cut metals in a variety of applications, using a plasma torch controlled by a computer. That sounds simple on the surface, but there are several layers of complex technology and engineering that work together to allow CNC plasma cutters to cut metals incredibly efficiently and accurately.

How does a CNC plasma cutter work?

CNC is used in a variety of technologies, and refers to computer-run machines that move and behave according to coding. In the case of a CNC plasma cutter, coding programmed on a computer describes the angles and dimensions of a part. It also tells the torch exactly when to turn on and off to achieve the desired cut.

As for the plasma torch, it forces gas or compressed air at high speeds through a nozzle. At the same time, an electrode between the nozzle and metal forms, creating hot, electrically ionised gas referred to as plasma. This superheated, super-fast plasma works in two equally important ways. First, it cuts through the metal with effortless precision. Then, it blows away the molten metal, leaving a clean piece.

What are CNC plasma cutters used for?

CNC plasma cutters are the standout choice for businesses cutting high volumes of electrically conductive metals like steel, metal, brass and aluminium. Hobbyists will love the ease and power of CNC plasma cutters too, provided they have a suitable space to work in. CNC plasma cutting is widely used across a variety of industries including:

  • fabrication
  • welding
  • manufacturing
  • art and design
  • automotive repair and restoration
  • salvage and scrappage
  • industrial construction.

Currently outsourcing your metal cutting to local contractors? The cost of CNC plasma cutters has dropped in recent years, and the money you can save by cutting metal in-house can be significant. Not only that, when you own a CNC machine you control the whole process, making lengthy lead times a problem of the past.

Are CNC plasma cutters better than hand-held plasma cutters?

Hand-held plasma cutters can also cut through a variety of metals, but they lack the computerised precision of CNC plasma cutters. While hand-held cutters rely on the steadiness of the user, CNC plasma cutters use computer programming and a mechanised straight barrel torch to cut precisely to design. The benefits of choosing a CNC plasma cutter include:

  • faster, more accurate cuts
  • automated control via a computer interface
  • cleaner edges on every piece
  • greater effectiveness with difficult and/or thicker metals like high strength structural steel
  • the ability to replicate high volumes of the same cut.

If your business is involved in serious manufacturing or fabrication, there’s no substitute for a quality CNC plasma cutter.
