Securely clamped A zero-point clamping system enables fast and precise workpiece changeovers while reducing setup and machine downtime. Workpieces are positioned accurately and clamped securely within seconds.

The patented EROWA Giant Tooling System (GTS) has been specifically developed for large and heavy workpieces in rotary applications. It combines precision, stability and process reliability for heavy-duty machining. Its robust geometry is ideally suited to automated manufacturing processes as well as the production of large workpieces with crane loading.

Standardized setup processes reduce machine downtime and increase productivity.

GTS GIANT TOOLING SYSTEM

Precision and stability for large workpieces Whether high machining forces, heavy workpieces or demanding mill-turn operations - the GTS delivers the required stability, precision and process reliability.

Precise positioning Flexible arrangement of the GTS chucks – tailored to the workpiece, the machine and the process requirements.

Secure clamping A clamping force of 80 kN per chuck provides the foundation for stable machining processes.

Reliable clamping force retention The self-locking clamping mechanism maintains the clamping force even if there‘s a loss in hydraulic pressure.

THE FACTS

• Modular clamping system • 80 kN clamping force per chuck • Pressure-free clamping for maximum safety Reliable process automation Locking and open-position monitoring, together with the integrated cleaning function, support reliable automated operation.

• Consistent precision despite temperature fluctuations • Optimized for rotary applications • Locking and open-position monitoring • Integrated cleaning and monitoring functions • Ideal for automated applications

Process-safe, reliable & efficient The GTS adapts flexibly to different manufacturing concepts – from manual operation to fully monitored automation. Thanks to its modular design, the number of chucks can be individually adapted to the workpiece and process requirements.

Clamped without hydraulic pressure, monitored and cleaned – for high process reliability and machine availability. The thermally compensating clamping technology ensures precise positioning even under temperature fluctuations.
