Plasma cutting of metal allows to obtain metal products with precisely observed proportions in relation to the model. High accuracy is ensured by the fact that all calculations and movements of the cutter are controlled by a computer. The equipment is capable of performing industrial
processing and cutting. The division (cutting) of a monolithic workpiece is carried out by thermal heating, while the cutting element is the ionized current of a plasma arc.

Advantages of plasma metal cutting

Avotini uses KOIKE Deltatec machines, which provide a narrow cutting width as well as clean edges. As a result, thermal deformations are minimal even for thin cut parts.

Advantages:
High cutting speed compared to gas or laser cutting (compared to gas-plasma cutting, processing is performed almost 7 times faster), since no preheating of the cutter is required. Improved quality of part processing – no additional processing, grinding is required, the amount of waste is minimal. It is possible to work with aluminum, mild and stainless steel, cast iron and other materials.
The thermally exposed area is minimal, the cut is narrow, so there is no thermal deformation, and even thin sheets can be cut.
Compared to laser, plasma has the advantage of processing parts with a thickness of more than 50 mm, exceeding the speed with lower energy costs, resulting in a price advantage. Products cut with laser technology have cleaner edges.

Application areas of plasma metal cutting technology
Plasma cutting is used in mechanical engineering, utilities, aviation and shipbuilding, as well as in the manufacture of metal structures. The devices are used in operations such as pipe cutting, sheet metal cutting, cutting out figured parts, hole
drilling, stainless steel and coil processing. With the help of plasma cutters, it is possible to produce strips, parts with complex configurations: trays, base plates, anchors, embedded parts, blanks for welding structures,
base plates, pipes, flanges, angles and other similar fastening elements.

Working principle of plasma cutting machine
Plasma is formed due to the heat of ionization of a gas, which is provided by an electric arc. The heated air becomes a good conductor of electric current. In ordinary
An electric arc in a plasma torch (torch) in a plasma cutting machine creates a plasma arc. Initially, an arc with a temperature of up to 5,000 ⁰C is created between the cutter nozzle and the material. The electric arc is struck, and then a gas capable of forming plasma is added, as
as a result, the temperature rises to 30,000 ⁰C. Cutting is performed with a plasma flow, without causing mechanical effects on the part. The equipment differs in the design of the plasma torch (torch), as well as the characteristics of the arc, which can be direct or indirect action.
