Plasma cutting machine

Plasma cutting machines, plasma cutting systems

Plasma cutting machines for fast and precise cutting of sheet metal and steel plates with medium wall thicknesses.

The plasma cutting systems in portal design are used in steel construction, steel trade, plant construction and metal construction for thermal cutting with a plasma cutting source of flat steel and steel sheets.

The plasma cutting system is particularly economical for cutting sheet metal and profiles with wall thicknesses ranging from 3 mm to 80 mm.
Plasma cutting systems are supplied by manufacturers such as Kjellberg® and Hypertherm® to internationally renowned machine manufacturers, who integrate them into their flame cutting systems.
The plasma cutting sources sold most in our sector are from the two manufacturer brands Hypertherm or Kjellberg. Of course, laser and plasma sources are becoming ever cheaper and more effective and are therefore achieving ever higher accuracies and cutting speeds. As a result, even thicker materials can be cut economically with a plasma torch in the future.

Plasma cutting machine or plasma cutting system

If the material thickness to be cut is generally greater than 3 mm and less than 80 mm sheet thickness, plasma cutting is used depending on the availability of the machine equipment. The plasma cutting machines are usually equipped with modern cutting sources from Kjellberg® and Hypertherm® and are suitable for cutting sheet thicknesses of up to 80 mm. Plasma cutting systems are very economical for many flame cutting companies due to the high cutting speed. However, a precise plasma cut can only be achieved if the system also has precise guidance of the gantry and the torch unit. A stable machine cutting table in conjunction with a suitable extraction table and an efficient filter system is also very important. The filter system must be capable of precisely extracting and filtering the toxic smoke and dust.

Plasma cutting

Plasma cutting is a fast thermal cutting process that is becoming increasingly important in the steel industry. In plasma cutting, a plasma jet of up to 30,000 degrees is generated at the cutting nozzle. This high-energy plasma jet cuts the metal plates at a high cutting speed. Up to a material thickness of 60 mm (soon up to 80 mm), a higher cutting speed can be achieved with mild steel (and other conductive materials) than with oxyfuel cutting. When buying a new machine, most machine users are increasingly opting for plasma cutting technology. This fast plasma cutting technology is therefore used on gantry cutting machines, sheet metal processing centers, drilling machines, notching machines and tube cutting machines.

By using modern plasma cutting sources from manufacturers such as Kjellberg® with the HiFocus system and Hypertherm® with the HyDefinition system, significantly better cutting qualities are achieved even with thicker materials. Plasma cutting systems are available from 100 Amp. to 400 Amp. Power. If the plasma cutting systems are also equipped with True Hole or Contour Cut technology, the progression of the plasma cut is only slight. The hole quality and angular accuracy have been improved many times over.

The choice of gas depends on the component material to be processed. When processing mild steel, aluminum and stainless steel, it is possible to use inexpensive compressed air as the plasma gas. In order to achieve a higher cutting quality, the gases nitrogen or a mixture of argon and hydrogen are also used for plasma cutting of aluminum or stainless steel.
In steel construction, however, the use of oxygen is widespread, even if the service life of wear parts such as cutting nozzles is reduced. However, the cutting speed is increased and the quality of the plasma cut is improved. The slag burr is reduced and thus the time-consuming deburring process.

Plasma cutting system manufacturers

Well-known manufacturers of plasma cutting machines with extensive equipment are Messer Cutting, ESAB, Ficep, Zinser, Voortman, Vernet-Behringer, Microstep, Sato, mgm, Warcom etc.

Used plasma cutting machines and plasma cutting systems

Nenok always has used plasma cutting machines in good condition from various manufacturers. Combined cutting machines with a drilling unit are also available; these are equipped with one or more plasma cutting systems.
