Giant tooling system machines large and heavy workpieces

The Giant Tooling System (GTS) from Erowa is designed for machining large and heavy workpieces. Engineered specifically for rotary applications such as mill-turn machining, the GTS provides a robust and reliable solution for even the most demanding manufacturing environments.

At the core of the system is EROWA’s zero-point tooling technology, which enables rapid and highly precise workpiece changes. The company says the tooling drastically reduces machine setup times and downtime. With the GTS, a wide range of large workpieces can be accurately positioned and securely fastened in record time.

Each GTS chuck delivers a clamping force of 80 kN, ensuring a rigid and vibration-resistant connection to the machine table. The result is superior machining stability, improved surface quality, and greater overall process consistency.

The modular design of the GTS allows flexible configuration — chucks can be arranged to accommodate varying pallet sizes, fixture setups, and specific production requirements. Operation remains simple and intuitive: GTS clamping rings are mounted on the workpiece carrier or fixture and are automatically and precisely engaged in the GTS chucks.

The GTS is also built for automated operation. Integrated safety and monitoring features — such as hydraulic open/close control and pneumatic surface cleaning — ensure reliable chuck operation and protection against contamination. Together, these systems guarantee secure positioning and smooth processing, even under challenging conditions.
