NERTAJET HP

High Plasma

High Precision, High Productivity, pro The alternative to laser cutting.

The High Performance of plasma arc machining using NERTAJET HP installations stems from: · the wide choice of powers (currents), providing the best match between the thickness of the material and the required cutting quality, · a wide choice of plasma arc processes (utilised gases), providing the best match between the nature of the material to be cut and the required cutting quality, · the fact that the same NERTAJET HP installation lets you work: - either in the conventional way (very high cutting speed), - or in the High Plasma mode (high cutting accuracy). The High Plasma NERTAJET HP is a development of the standard plasma arc process representing an alternative to laser cutting: · in quality and productivity This cutting tool ensures: - close metallurgical, dimensional and geometrical tolerances of cut parts, - high quality of cut face surfaces, - cuts free of adhering droplets or slag, · in operating cost With NERTAJET HP installations, everything contributes to an economic cutting price: - increased service life of consumables, - exactly the required electrical power consumption (choice of lowest current suiting thickness to be cut and overall power efficiency of around 98%), - low gas consumption, - cutting with multiple NERTAJET HP plasma arc installations example: two-torch, simultaneously (productivity) or sequentially (quality), - wide choice of machines suited to various sectors of industry (from jobbing cutting to integrated manufacture), with a good return on investment.

Economic aspects

The NERTAJET HP plasma cutting process lies mid-way between oxycutting and laser cutting in terms of plant investment, cutting thickness range and cutting quality. However, its high cutting speeds offer the lowest operating costs per cut metre.

CUTTING STAINLESS STEELS

In contrast to Laser cutting, the plasma cutting process is able to cut greater thicknesses of stainless steel than of non-alloy steels at a given power (for example, at 120 amperes, it is possible to cut up to 20 mm of non-alloy steel, but as much as 35 mm of stainless steel).

With the NERTAJET HP DUALGAZ plasma process, SAF brings you a high quality solution for cutting stainless steels in thicknesses from 0.8 to 12 mm. DUALGAZ is a new technology successfully developed by Air Liquide Welding engineers, bringing to bear their profound knowledge of every aspect (the electronics, mechanics, gaseous physics and chemistry, metallurgy, etc.) of the plasma procedure. This innovation combines the characteristics of arc control provided by NERTAJET HP technology with the advantages offered by special gas mixtures. By introducing special constituents into the gas mixtures, it is possible to act upon the physical and chemical aspects of the procedure. As a function of the grade and thickness of the stainless steel to be cut, the type and proportion of the different constituents is adjusted in order to attain the highest possible quality of cut. In this way, every individual case is defined to furnish a personalized solution for the work of each customer.

gas 2 N2 O2 or N2 O2 CH4

Advantages to customers · Flexibility: DUALGAZ is suitable for all grades of stainless steel, including titanium stabilized grades. · Quality: no flashes, even in zones where the machine slows down (angles, etc.) Cut parts can be used directly without any retouching. · Quality: low surface roughness (less than that obtained by Laser cutting). · Quality: light colour of cut surfaces. · Quality: very good control of relief (<2°). · Reproducibility: excellent consistency of cut throughout the life of wearing components (nozzles and electrodes). · Ease of use: can be employed on all common digitally controlled gantry machines. Its use on high precision equipment such as PLASMATOME HP, displays the potential of the procedure to the full (high quality geometry of parts).

The NERTAJET HP autonomous cycle is the "intelligence" of the plasma arc installation. To use a musical analogy, it is the conductor of all the orchestral players implementing the plasma arc cutting process: installation components, machines, operators. It is characterized by: · a single mode of operation throughout the range of NERTAJET HP installations. · customizing to suit the application through the facility to store cutting parameters. · high safe by control, favoured by: - a design enabling the autonomous cycle to be integrated into the control console of the machine so that the operator has a direct view of the cutting process and parameters. - availability and front panel display of the autonomous cycle and hence all functions necessary and useful for control and maintenance of the installation. · open-ness to modern communications - facilitating the updating of plasma arc process control software and cutting parameters. - meeting future needs for integration (multitorch, remote diagnosis, etc).
