The EROWA Universal PowerChuck – UPC is an advanced clamping system designed for exceptional precision, stability and reliability in a variety of machining applications. Regardless of dealing with small or large workpieces on milling, EDM, grinding, drilling or on measuring machines. The UPC system adapts to your needs, making it an invaluable tool in any manufacturing environment.

Unbeatable accuracy and performance of the UPC chuck

The EROWA UPC zero-point clamping system sets new standards for precision in clamping systems. With a repeatability of less than 0.002 mm, it ensures that every part is precisely positioned. This is crucial for applications that require high precision. It provides a clamping force, up to 50 kN with the optional reclamping function (up to 80 kN). Consequently, during processing, even the heaviest workpieces are secured. In addition, it enables 5-axis machining, which further increases versatility

Versatility for all workpiece sizes

One of the outstanding features of the EROWA UPC is its adaptability. The integrated ITS chuck ensures the seamless integration of the EROWA ITS 50 or ITS 100 workpiece carriers. This combination makes the UPC system suitable for a wide range of applications, from small precision components to large industrial parts. Furthermore, it minimizes downtime and maximizes productivity.

Robust and safe clamping system

The EROWA UPC zero-point clamping system’s design provides the highest level of stability and safety. The system is extremely resistant to tilting due to its widely spaces contact surfaces. This ensures that the workpieces remain stable even during intensive machining operations. It is stable even with larger workpieces The robust clamping force with secure design makes the UPC system ideal for applications with required precision and strength.

This high-performance system is also characterized by exceptional reliability. The self – locking ball lock maintains full clamping force even in the event of a pressure drop. This ensures continuous and stable operation. The design of the UPC with ground functional surfaces and centering elements contributes to its accuracy, making it the ideal solution for tasks that require high precision.

The UPC 2.0 clamp is equipped with a special rubber seal that is 100 % tight and prevents the penetration of chips and coolant. As a result this protects the system from environmental influences. The seal, along with automatic compressed air cleaning, ensures that the contact surfaces remain clean and functional, maintaining the high long-term performance of the UPC system.

Compact design with maximum compatibility

The EROWA UPC has a low heigh design. This provides more space for workpieces and enables easier integration into existing machining setups. The compact design does not compromise performance, making the UPC system a suitable choice for a variety of processing environments.

Compatibility is another key feature of the UPC system. The clamps have a mounting hole pattern that allows easy installation on almost any machine table without the need for additional adjustments. In addition, EROWA offers customized solutions for customers. This means they can design a customized solution for you that will meet your needs.

EROWA UPC ready for automation for higher productivity

The fully automated EROWA UPC is it the ideal choice for manufacturers looking to increase efficiency and reduce manual intervention. The system can be easily integrated with EROWA robots. This enables automated pallet handling and workpiece exchange. This automation capability not only increases productivity, but also ensures consistent quality across all machining operations.

In addition to the automation functions, the UPC system offers individual air management via an adapter on the back, which allows direct mounting on the machine table without the need for an intermediate plate. This feature further simplifies integration and increases the overall efficiency of your manufacturing process. Investing in Erowa UPC means equipping your workshop with a highly accurate, versatile and long-term palletizing system that will increase productivity and ensure consistent processing quality.
