• High rotational acceleration and rapid indexing for improved productivity.
• Compact design with high rigidity and minimal thermal growth.
• Integrated positioning feedback and clamping systems for seamless CNC integration.

Applications

• High-precision 4th/5th axis machining requiring minimal setup and maximum repeatability.
• Micro-machining, tool-and-die, and aerospace component production.
• Robotic and automation rotary stages where high torque and high accuracy are critical.
• Continuous indexing operations in high-volume production requiring tight tolerances.

Technical highlights

• Direct-drive torque motors with positional repeatability measured in arc-seconds.
• High clamp/unclamp torque for rigid work-piece holding.
• Table diameters and motor sizes matched to machine tool axis and load requirements.
• Minimal axial/radial run-out and low thermal drift, enhancing surface finish and part accuracy.
