Purpose of the development: Normal plasma cutting is used for cutting materials with acceptable quality and are cost effective.

Advantages over analogues: Normal plasma cutting is used for cutting materials with acceptable quality, and are cost effective, cutting to separate the two gas supply allows to achieve optimum results with different metal cutting, cutting high density plasma processing is applied to sheets having a thickness of 0.5 to 25 mm.; Underwater plasma cutting became widespread due to the increasing demands for environmental friendliness of production; stability of the plasma torch height position above the sheet has high performance and performed well in harsh industrial environments, the system of protection of the plasma torch also protect against collisions with special devices that give an alarm when the application mechanical force to the plasma torch, and also provide a soft response to an applied force of the plasma torch and plasma torch exact return to its original position when removing this effort.

The development stage readiness: Introduced in production

Description of the development:
()
The traditional alternative oxy-fuel cutting, plasma cutting is used, which uses a higher temperature. The plasma cutting technique is based on the use of DC arc plasma direct where the electrode is a cathode and the metal rezrezaemy - anode. The essence of the process is the local thermal effect on the material being cut heat the compressed arc and plasma flow removal of material from cutting area. Plasma is capable of providing a clean and fast cutting in a wide range of thicknesses. The characteristics of the plasma cutting machine can be controlled using a variety of gases, change their flow and pressure, change the speed of movement of the cutter diameter nozzle to modify a protective gas. This control provides operators with the ability to produce a clean, precise cutting of a wide range of thicknesses of different metals and alloys. Advanced plasma cutting systems provide a conductive 0.3 ... 150 mm or more. Various systems and plasma technologies: normal plasma cutting, in which case only one gas (generally air or nitrogen), with a separate cutting feed two gases - a plasma forming gas is, the other - the protective, cutting plasma high density applied to the sheet processing thickness from 0.5 to 25 mm., underwater plasma cutting: for use underwater plasma cutting is used for high-power plasma current of more than 100 A stabilization of the plasma torch height position above the sheet - a two-step system. Initially, the cutter is set at a predetermined position above the sheet using inductive sensors. When cutting the basic system works. The principle of operation of the main system is based on measuring the voltage across the plasma arc and maintain it at a fixed level by automatically moving the torch up / down for extension / reduction of the arc. The system responds to changes in the arc voltage less than 1 V, the system of protection against collisions torch - a powerful and therefore expensive systems, torches also protect special devices that give an alarm when the application of mechanical force to the plasma supply (for example, hitting the overturned cut part), as well as provide a soft response to an applied force of the plasma torch and plasma torch exact return to its original position when removing this effort. There are both purely mechanical and pneumatic devices. Produced plasma cutting machines are equipped with the world leader in the production of plasma cutting - the company "Hypertherm", ensuring production of a wide range of equipment for plasma cutting and marking, can be equipped with other types of plasma systems.
