Extra High Accuracy (SigmaTau PKM)

Robot cells with Cognibotics calibration are highly efficient solutions to work on large precision parts. However, for parts with extra demanding tolerances when the traditional robot accuracy is not enough, and where workpieces are 3 meters or larger, the SigmaTau PKM is likely the best solution. The SigmaTau is bridging the gap between CNC machine tools and industrial robots by providing the right balance of performance and cost. Tolerances down to 0.05mm can be achieved over large volumes.
A SigmaTau PKM robot can be adapted to different processes with high accuracy and high process force over large workspaces. It is suitable for both lightweight processes such as Laser Welding or Inspection to heavy operations such as Grinding, Drilling, Riveting, Milling, or Friction Stir Welding.
