We can plasma cut a variety of materials, including carbon steel, stainless steel, aluminum, high strength steel, abrasion resistant steel, and other alloys.

At G.E. Mathis Company, our CNC high-definition plasma cutting capabilities have served a variety of markets and industries, including agricultural, construction, heavy equipment, mining and military. We also have experience in manufacturing components for a diverse range of applications, such as lifting equipment, truck cranes, wear parts, boom components and frame rails, among many others. Simply put: There are few projects our plasma cutting capabilities cannot undertake.

Typical Lead times average from 1 to 2 weeks for prototype to production runs.

Precision CNC high-definition Plasma Cutting

When a gas is subjected to extreme heat, it begins to ionize. This ionized gas then becomes plasma, a more electrically conductive state of matter.

Precision CNC high-definition plasma cutting harnesses plasma’s conductive properties to cut conductive materials such as carbon steel, stainless steel, and aluminum. Its ability to use the energy found in plasma makes it an ideal cutting choice for many types of components.

The Plasma Cutting Process

A plasma cutter consists of several components:

  • A plasma power supply capable of generating 200 to 400 volts of direct current, which powers the plasma arc responsible for ionizing the gas and regulates the power output based on the material’s type and thickness
  • An arc starting console capable of generating 5,000 volts of alternating current at 2MHz, which generates the spark inside the torch that creates the plasma arc
  • A plasma torch through which ionized gas passes

When the arc from the power supply is combined with the gas, it results in a plasma jet that can reach a maximum temperature of 40,000°F. This jet then passes through an alloy copper nozzle, allowing the torch to cut through any conductive material.In turn, the plasma torch entails the following components:

  • An electrode connected to the negative side of the power supply
  • A nozzle connected to the positive side of the power supply
  • A gas baffle used when swirling the gas

The actual cutting process begins by sending a start input to the plasma system. After starting the power supply, the system places a negative voltage on the electrode located within the plasma torch. Gas then begins to flow to the torch while the baffle begins to swirl the gas.

During plasma cutting, the gas needs to be swirled for maximum cutting efficiency and quality. Swirling is often achieved by injecting water at the point where the arc exits the nozzle, further constricting the arc.

At the next stage of the process, contacts in the nozzle are closed, allowing it to connect to the positive side of the power supply. A high-frequency generator then causes a spark to pass between the nozzle and electrode, ionizing the gas. The pilot arc begins to flow between the electrode and nozzle, the gas flow blows the arc out of the nozzle, and the pilot arc makes contact with the material to be cut. After the main arc increases power to the cutting amperage, the shield gas restricts the plasma arc to ensure a clean cut.

Advantages of Plasma Cutting

CNC High-definition Plasma cutting has a number of significant advantages over alternative cutting methods. Some of its benefits include:

  • The ability to cut up to 500 inches per minute, or about five times faster than other methods
  • Better cut quality
  • The ability to cut through thick steel, aluminum, and other metals
  • Increased safety, since it relies on gas that isn’t highly-flammable

CNC high-definition Plasma cutting offers quality and reliability, and consistently produces components with clean cut edges and weld prep bevels. This can save time down stream by eliminating the need for extra handling in a secondary beveling process. Because of this, Hi-def plasma cutting can be a more cost effective method than laser or water-jet cutting, making it a great choice for certain situations
