Frequently Asked Questions
A direct-drive torque motor rotary table has no gearbox, eliminating backlash and wear while providing high speed, high acceleration and excellent positioning accuracy. Our Torque Motor Rotary Tables are widely used in 4th/5th axis machining centers.
The RAS Series Torque Motor Rotary Table achieves high positioning accuracy with an integrated high-resolution encoder, and our clamping system provides high rigidity during machining. Accuracy depends on the encoder and table model — we will confirm the specification.
Direct-drive tables achieve high rotational speeds and handle large workpiece loads. Send us your workpiece weight, table diameter and speed requirements for a selection recommendation.
Yes. We supply Torque Motor Rotary Tables as complete systems including the torque motor, encoder, clamping unit, driver and controller, so the table is ready to integrate into your machine.
Our tables use pneumatic or hydraulic clamping systems that lock the table rigidly during heavy machining while allowing high-speed indexing when unclamped. We select the clamping type based on your process.
Price depends on table size, accuracy and options. Standard models ship in 15–20 days; contact us for a detailed quotation and technical proposal.
