• Direct‑drive spindles deliver up to 11 kW power, 50 m/s wheel speed.
• B‑axis swivels 240° with 0.0001° resolution, 8‑second 180° shift.
• Concentricity accuracy reaches 0.5 µm; internal spindle up to 125,000 rpm.
• Turnkey packages include machine, NC program, tools, coolant, and support.

Pulse Analysis

The demand for versatile, high‑precision grinding solutions is rising as manufacturers seek to streamline production lines and reduce equipment footprints. EMAG’s UG Series answers this need by delivering a universal platform capable of internal, external and out‑of‑round grinding. By consolidating four size categories into a single family, the series lets job shops and component makers replace multiple dedicated machines with one adaptable unit, cutting capital expenditures and floor space while maintaining tight tolerances required by modern engineering.

Technical innovation drives the UG Series’ competitive edge. Direct‑drive spindles eliminate belt‑induced vibration, providing up to 11 kW of power and wheel speeds of 50 m/s, while the B‑axis offers a 240° swivel range with 0.0001° resolution and rapid 180° repositioning in eight seconds. Precision‑engineered workheads achieve 0.5 µm concentricity, and high‑frequency internal spindles reach 125,000 rpm for demanding aerospace and automotive components. The FANUC 0i‑TF Plus control, complemented by optional C‑axis functionality, ensures intuitive operation and seamless integration with existing CNC environments.

Beyond engineering, EMAG’s turnkey offering and extensive service network enhance the business case. Packages include the machine, NC programming, grinding tools, coolant systems and work‑holding technology, delivering a production‑ready solution from a single supplier. With U.S. and Canadian support hubs and a global technician pool, downtime is minimized and spare‑part logistics simplified. For manufacturers targeting higher throughput and tighter quality control, the UG Series represents a strategic investment that aligns with Industry 4.0 goals and the evolving demands of the automotive and aerospace supply chains.
