Robotic Plasma Cutting Solutions

Industrial plasma cutting uses a high‑velocity jet of ionized gas to cut conductive materials such as carbon steel, stainless steel, or aluminum. The plasma arc melts the metal while compressed gas blows away molten material, allowing fast, accurate cutting of medium to thick plates with minimal mechanical stress.

Plasma systems excel in:

High‑speed cutting of thick materials
Harsh industrial environments (heat, sparks, fumes)
Applications requiring robustness rather than micrometer‑level precision
Cost‑efficient cutting compared to some laser systems

Advantages of using 6‑axis robot arms in plasma cutting

Enhanced reach and multi‑angle flexibility

Equipping a plasma torch on a 6‑axis robot unlocks far more flexibility than fixed CNC plasma tables. Robots can process large parts, irregular geometries, angled bevels, tubes, frames and 3D structures — impossible with traditional 2D gantry machines.
This flexibility mirrors the benefits described in laser applications such as controlling complex tool orientation on curved surfaces.

Multi‑process adaptability

A robot can switch between cutting tasks, part geometries, or torch orientations without mechanical modifications, allowing quick changeovers and supporting high‑mix manufacturing.

Improved productivity and safety

Robots maintain consistent torch speed, stand‑off distance, and motion stability, which improves cut quality while protecting operators from heat, sparks, noise, and fumes.

Stäubli plasma cutting robots: key features and benefits

Reliable path accuracy for consistent cut quality

Although plasma cutting doesn’t demand the same micrometer path precision as laser, controlled and stable trajectories remain essential for bevel cuts, contours, and consistent kerf width.
Stäubli’s vertically integrated motion control chain — from drives to motors to gearboxes — ensures smooth orientation control and stable motion, even on large trajectories or thick materials.

Rigid and enclosed structure

The fully enclosed, rigid robot arm resists deformation under dynamic loads, ensuring consistent torch stand‑off and trajectory stability. Its robust structure withstands sparks, fumes, and vibrations, delivering reliable accuracy in demanding plasma cutting conditions.

Stable trajectory control for smooth cutting

Stäubli’s advanced motion control ensures smooth trajectories on large contours and bevel profiles. The robot’s rigidity enables stable torch orientation during direction changes and 3D motions, while fast, controlled transitions reduce non‑productive time.

"After comparing and analyzing all critical assessment points, a shortlist of 3 robots was made and tested in real life in our R&D facility. The results of our testing was that the Stäubli robot the best overall solution for our application. Criteria like repeatability, traceability of movements and smoothness of cuts were met or exceeded for demanding."
