FINE FOCUS Plasma Cutting with Robots Pioneers in Plasma Cutting since 1959 made in Germany Versatile • Efficient • Safe FINE FOCUS Plasma Cutting of Three Dimensional Structures Industrial robots are excellently suited for economic large-scale production, for effective low-volume production and even for piece production. Kjellberg plasma cutting systems can be adapted to all robots and robot controls in the market. Robot-assisted plasma cutting offers all features that are required for the use in industry and craft: l l l l Cutting to length, contour cuts and cutting of openings on pipes l Cost-efficient cutting Simple programming and operation High cutting speeds High cut quality, nearly no rework required High flexibility It is possible to cut all electrically conductive materials and diverse types of work-pieces: l l l l Structural components for vehicles Pipes and containers Hollow profiles, open and closed profiles as well as bulb flat profiles Dished bottoms Plasma cutting with robots offers a number of possible applications: l l Cutting a window into a passenger car sidewall l l l l l Cutting on pre-selected paths or of workpieces with greater tolerances on paths with automatic torch height control Vertical cutting (straight cuts and holes) Complex three-dimensional contours Precise and variable bevel cutting With some systems also marking Underwater plasma cutting Plasma cutting on hot work-pieces At present, Contour Cut is the latest way of highquality plasma cutting. It is the further development of the HiFocus technology for cutting fine inner and outer contours in mild steel and convinces with: l l l Cutting of bevels of up to 50°, mostly for weld preparation purposes l High cut quality and contour accuracy Low angular deviations and smooth cut surfaces Excellent repeatability and dimension accuracy High productivity at low costs FINE FOCUS High Flexibility of the Production Today, robot-assisted cutting technique is mainly used for the processing of three-dimensional workpieces. The most important users are the automotive industry and its suppliers as well as enterprises in container and pipe production, steel construction and shipbuilding. In these sectors, the plasma cutting technique has already many times proven its advantages with regard to flexibility and cost benefits compared to other technologies. Examples from the Automotive Industry End-cutting of hydro-formed axle components for a passenger car Cutting of a passenger car B-pillar from high-strength material Contour cut on a section of a vehicle exhaust system from CrNi-materials (method: Underwater plasma cutting for trim-free inner pipe surfaces and clean cut surfaces) Kerf on a galvanised passenger car body, the corrosion protection layer next to the groove is preserved on the work-piece surface End-cutting of a safety profile for a passenger car body Gap bridging: hole cutting with high cut quality on spot-welded sheets FINE FOCUS Plasma Cutting in Container and Pipeline Construction For cutting on curved surfaces, the robot requires a good sensor system with respect to the data exchange with the plasma cutting system in order to achieve a constant torch height. So the conditions are fulfilled for achieving excellent bevel cuts especially in this industrial field and, thus, reducing weld preparation costs. Precise cutting of a pipe socket and the opening on the pipe Holes in dished bottoms also with bevel cuts for weld preparation Pipe end cutting of an external swivelling axis Plasma cutting of a core hole with circumferential counter bore Cutting Tasks in the Shipbuilding Industry One of the typical plasma cutting tasks in shipbuilding in connection with robots is the cutting of profiles. End cutting and hole cutting with and without bevels in diverse flat profiles, angle profiles and above all bulb flat profiles can be done easily and quickly. Also strongly varying material thicknesses on one workpiece are manageable without any problems. Notches on diverse profiles Bulb flat profiles are characteristic for the shipbuilding industry FINE FOCUS Plasma Torches for Special Applications For plasma cutting with robots, Kjellberg Finsterwalde has developed a wide variety of torches. Depending on the task, several models are on offer: l As straight version or with 60° or 90° angled cutting heads – they make it possible to cut even highly structured work-pieces optimally l With quick-change head With Kjellberg plasma torches, bevel cuts up to 50° are possible. In connection with special torches, bevel cuts up to 60° are possible.
