If you are not involved in the metal fabrication business at the moment, would you have the slightest idea on what a CNC profile cutter is? Or how it is relevant in relation to the metal fabrication business?
Before making any decision to embark yourself into the world of CNC plasma kits Australia industry, you need to embrace a few things about this business and industry first. Doing so will help ensure that you will not grope in the dark, instead, you are empowering yourself with the right information and thus increasing your chances of making the right choices.
Let the following points serve as your ultimate guide in CNC cutting machines and how these all work.
CNC Profile Cutters: What Are They?
CNC cutting machines, as the name suggests, are cutting tools, extraordinaire. The usual application for this technology can be found usually in the metal fabrication industry. What makes it distinct from other types of cutting methods is the fact that they make use of a plasma torch which is controlled from a computer.
Plasma CNC cutting machines usually operate by forcing compressed gas or air through a nozzle. The moment that an electric arc is introduced here, to the gas, it becomes ionized gas and thus plasma is created. Plasma is the fourth state of matter and can be utilized to cut through tough objects like metals.
Compared to conventional methods of cutting through metal, CNC profile cutters differ in various aspects like price, size, and functionality. The high level of accuracy of CNC cutting machine is their main selling point. They are capable of slicing through materials at speeds of up to 500 inches every minute.
In order to function correctly, this type of cutter would require an assist gas and a plasma gas, and the amount of which for those would depend upon the material being cut.
What is Plasma?
Primary education taught us that matter is comprised of 3 states only, namely solid, gas, and liquid. But there is another state, the plasma state. In order to illustrate how distinct these states are to each other, we need to cite an example. Take water, for instance, it is considered by science as a universal solvent and is one of the most abundant natural compounds.
Water is the liquid form of this compound. Place water inside your fridge, and later you will have ice which is the solid state. Boil water (which means you are giving it more energy in form of heat) and you will have steam. Steam is the gaseous state of water.
If you will subject steam to further heat, which is giving it more energy, that gaseous state will become ionized and becomes electrically conductive. This is now referred to as the plasma state.

The Anatomy of a CNC Profile Cutter Cutting Through a Metal
In a plasma cutting process, the electrically conducting material is being utilized to transfer energy from an electrical source. This is made possible by the use of the plasma cutter torch to the object, the metal sheet that needs cutting/trimming.
A CNC cutting system needs to have an adequate supply of energy. It is equipped with a starting circuit and a torch. They work hand in hand to produce the required electrical power, ionization capability, and process control. Otherwise, it runs the risk of producing a substandard quality of cuts.
Power supply here is crucial and must supply your system with a stable and steady DC power source. The amperage of the current output will have a direct role to play in determining the cut thickness and the speed of the system in carrying out a cutting project. The main role of the power supply in this kind of setup is to provide the right amount of energy to sustain the plasma arc following ionization.
