CNC Plasma Cutting

CNC Plasma Cutting

At AD Metalworks we use the latest Swift-Cut CNC Plasma Cutting tables allowing us to cut a range of metals, including steel, stainless steel and Aluminium.

Sizes range up to 2500mm by 1250mm and 50mm thick, with a very high degree of accuracy and with a smooth finished edge.

Why Choose Us

Coming after solid, liquid, and gas, plasma is the 4th state of matter. When you heat gas enough, the atoms split, separating the electrons form the nucleus. Once the heat releases the electrons, they begin to move quickly. These electrons are negatively charged and as they move they leave behind a positively charged nuclei known as an ion. When these ions and electrons collide they release energy– lots of it!– and it is this energy that gives plasma its great cutting power.

Plasma cutters operate by sending pressurised gas, such as nitrogen, argon or oxygen, through a small channel with a negatively charged electrode in the center of it. When power is applied to this negative electrode and the nozzle touches the metal, a circuit is created and a spark is generated between the electrode and the metal. This spark heats the inert gas to the point that it turns into plasma and it releases a direct stream. This plasma stream is approximately 16,649˚ C and moves at a speed of 20,000 feet per second. When it comes in contact with metal, the plasma reduces it to molten slag.

As long as power is supplied to the electrode and the plasma stays in contact with the metal, this plasma arc will be continuous. To maintain this connection, the nozzle releases a constant flow of shielding gas around the cutting area and the radius of the plasma beam will be dependent on the pressure of this gas shield.

We are prompt, efficient and place great emphasis on customer care because meeting the customer’s needs is of paramount importance to us.
