Güdel Extends Robotic Grinding with Vertical and Linear Axes

Integrated motion targets large-part grinding limits

Güdel is expanding the practical range of robotic grinding by combining vertical and horizontal motion around a single industrial robot, a configuration aimed at large fabricated parts where fixed-base automation often reaches its limits. The original report, published by Robotics & Automation News, describes a system that pairs a FANUC robot with Güdel motion platforms so one robot can cover a larger work envelope for grinding and surface finishing. According to Robotics & Automation News, the objective is to reduce the need for multiple robots and repeated part repositioning, both of which add cost, cycle time and process variability in heavy fabrication environments.

That matters because grinding remains one of the more difficult metalworking processes to automate at scale. Large weldments, frames and structural fabrications frequently require access across several faces and elevations, and conventional robot cells often compensate with oversized fixtures, headstock-tailstock positioners or manual intervention between passes. Güdel’s approach instead extends the robot’s working volume through a vertical axis and a floor-mounted travel axis, allowing the manipulator to maintain process orientation while moving around the part. As RoboticsTomorrow notes, the concept is positioned as “grinding beyond stationary robots”, with the emphasis on reach, stability and consistency for demanding finishing applications.

Why grinding automation is gaining priority

For production managers, the business case is straightforward. Grinding and surface finishing are labor-intensive, ergonomically difficult and highly sensitive to operator variation. Automating them can improve throughput, reduce rework and make quality more repeatable, especially where parts are large enough that manual handling becomes a bottleneck. The editorial angle behind this development is therefore broader than one product launch: grinding automation is becoming a core lever for manufacturing efficiency. In sectors such as heavy equipment, automotive structures, steel fabrication and general metalworking, the ability to process larger parts with fewer stations can directly affect floor-space utilization and labor allocation.

Technically, the use of a seventh axis or gantry-style extension is not new, but the current market trend is toward tighter integration between robot controller, linear motion and process tooling. Güdel has been active in this area beyond grinding. Automation World recently highlighted the company’s TrackMotion Floor systems, noting that these linear axes can move robots weighing up to six tons, including applications in automotive body-in-white handling and welding. That is relevant because the same design logic applies across abrasive finishing, arc welding and material handling: when the part is too large or too variable for a fixed robot base, integrated motion can be more efficient than multiplying robot count.

Implications for robot OEMs, safety and cell architecture

The significance of Güdel’s announcement also extends to robot vendor strategy. Although the showcased system uses FANUC, the underlying demand exists across the major industrial robot brands used in fabrication cells, including ABB, KUKA and Yaskawa, and in some lighter-duty finishing applications potentially even with collaborative platforms from Universal Robots or Doosan. For integrators, the key issue is not only payload and reach, but how accurately the robot maintains path quality when mounted on a moving axis under grinding loads. Abrasive processes generate continuous forces, vibration and dust, so axis rigidity, cable management, sealing and calibration become more critical than in many pick-and-place deployments.

Safety and compliance are equally central. Large grinding cells combining robot motion, linear travel and vertical lift require a risk assessment aligned with ISO 12100 for machinery safety and typically a control architecture consistent with ISO 10218 for industrial robots and robot systems. Where collaborative operation is considered, ISO/TS 15066 may become relevant, although most heavy grinding applications will remain fully guarded rather than collaborative. Electrical design and integration in Europe also need to consider applicable IEC and EN requirements, including machine electrical equipment principles under IEC/EN 60204-1. In practice, adding a floor axis and vertical travel changes safeguarding zones, emergency-stop circuits, access control and maintenance procedures, so the mechanical advantage must be balanced with a more sophisticated cell design.

What this means for welding cell integrators

What this means for welding cell integrators is that the same integrated-motion architecture now being promoted for grinding has direct relevance to robotic welding and cobot welding projects. Large weldments often face the same constraints as large grinding jobs: limited robot reach, awkward access angles, excessive part repositioning and long non-value-added moves. A welding cell built around a robot on a linear track, or around coordinated robot-plus-positioner motion, can reduce fixture complexity and allow a single robot to cover multiple stations or longer seam paths. For integrators designing turnkey systems, this creates opportunities to standardize modular cells where the same motion platform supports welding, grinding and post-weld finishing in a shared manufacturing concept.

There are, however, design trade-offs. Welding demands path repeatability, torch angle control, coordinated motion and process synchronization with power source, seam tracking and fume extraction. Grinding adds force control, spindle management and abrasive wear compensation. Integrators serving Tier-1 automotive suppliers or metalwork SMEs therefore need to evaluate whether a common linear-motion base can support both processes without compromising uptime or maintainability. The broader lesson from Güdel’s announcement is that external axes are no longer a niche add-on; they are becoming a core part of cell architecture for large-part automation. Companies assessing future robotic welding cells may want to compare fixed-base robots against track-mounted solutions early in the layout phase, especially where part families are growing in size or mix.
