What is a CNC Hi-Def Plasma Cutter?

A Plasma Cutter is a hand-held torch used in cutting a variety of metals.  

It is an excellent tool for quickly cutting through sheet metal, metal plates, straps, bolts, pipes, etc. A hand torch can be used for cutting small shapes from steel plate and as a gouging tool for back-gouging weld joints and removing defective welds. It is good to note that, when you use a hand torch, it is almost impossible to get the kind of accuracy and edge quality that is required in most metal fabrication.

So, how do we solve this problem?  

With a CNC Hi-Def Plasma Cutter! The term “CNC” is short for “Computer Numerical Control”, which means that a computer is used to direct the machines motion based on numerical codes in a program. A CNC Plasma Cutter can be used for cuts in metal similar to a hand torch. However, it does use a different type of plasma system. CNC Cutters are built with a table, designed to allow a computer to control the torch head producing clean sharp cuts.  

CNC plasma equipment is capable of cutting thick material on multiple axes using a mechanized cutting system rather than a handheld cutter. This process allows for complex welding seams that are otherwise impossible. As technology improves, CNC cutters offer even more flexibility, optimum safety, and faster operation.

There are 3 main types of CNC Plasma Cutting machines. These are differentiated by the forms of materials being processed and the flexibility of the cutting head.

  • 2 Dimensional – This is the most common type of CNC cutting. The cut edges are at 90° to the material surface. High powered CNC plasma cutting beds are configured to cut profiles from metal plate up to 150mm thick.
  • 3 Dimensional – This process is also used for flat sheets of metal but adds an additional axis of rotation. The cutting head of a CNC Plasma Cutting machine can tilt as it is cutting on a conventional 2 dimensional path. The result is an edge that can be cut at almost any angle not just a standard 90°.  
  • Tube & Section – This type of cutting is used for the processing of tube, pipe or any form of long section. The plasma cutting head usually remains stationary while the metal is fed through and rotated.
