The company SATO Schneidsysteme Anton Hubert e. K. in Mönchengladbach has been a successful manufacturer of CNC-controlled cutting machines in gantry and cantilever design for 25 years. The "Satronik" series covers oxy-fuel, plasma, laser and the water-jet range.
The company's flame cutting machines cut sheets from a few millimetres up to two metres. In order to ensure that they function perfectly in the long term in the tough everyday operating conditions, which are characterised by heat, flying sparks and extreme dirt accumulation, the individual components must be extremely robust and, like the system itself, state of the art.
This also applies to the innovative 3D plasma bevel unit, which has proven itself many times over in customer applications for about two years. With this system component, SATO Cutting Systems sets new standards in dynamics, precision and energy efficiency.
The programmable 3D plasma bevel cutting unit is used for machining in the weld seam preparation of structural and stainless steels. "We designed it to be exceptionally compact," explains director Reiner Schiffer. "As a unique selling point, the new design ensures an extremely small footprint on the machine as well as high dynamics in the actual cutting process. " 
The economic efficiency of the system is demonstrated, for example, in the area of multiple panel machining, which can be cut in one go without a break. Another advantage is the minimised waste. The low weight of the unit makes it possible to use it with compact machine types. The 3D plasma bevel cutting units with height sensing, which can be pivoted endlessly without rotation limitation, are in daily use as single- and multi-torch variations and cut bevel and trim sections up to 45°. With a stroke speed of 6,000 or 12,000 mm/min, it can be used for all plasma systems for bevel cutting.

The energy supply of a cutting system with two 3D plasma bevel units is ensured by energy supply systems from igus. On the x-axis with a travel of the entire burner system of 42 m, the undefined, which is openable from both sides, proves its efficiency. It is suitable for high speeds and accelerations as well as long travels and high additional loads. The main feed for the complete flame-cutting system runs through it.
Installed in three separate guides, three undefined are used for the transverse movements on the bridge to supply a 3D bevel unit. This means that six energy supply systems in a total of six guide troughs provide the supply lines to the two burners. They are easy to assemble and have a long service life.
The two bevel units each have an energy supply system in a bracket version. It guides the complete system overhead to the burner in each case and ensures that all up and down movements are carried out safely over the long term.
On the very compact 3D plasma bevel units, the heart of the machine, the undefined, which is now available in its third generation, proves its worth in all directions. It has been specially developed for demanding 6-axis robot applications.  The unit moves in several axes. The triflex R 3D energy supply systems, TRC series in enclosed design, and TRE in easy design for simple pressing in of the cables have proven themselves for guiding a wide variety of cables. While all undefined, including the cooling, are safely guided in the TRC version, all special cables, which are responsible for the initial ignition of the combustion engine or for emergency monitoring, for example, run through the TRE version. In addition, there are also the signal cables, which can be pressed into the chains quickly and easily from the outside using the "Easy" principle.
