AHH SERIES

Mini one-armed harmonic tilting rotary table - THE COMBINATION

The AHH series is a rotary/swivel table in single-arm design driven by a Harmonic Drive gear and is popular as a low-cost positioning unit in CNC machine tools or in automation as a fourth and fifth axis. Siemens and Bosch-Rexroth are available as drives. The AHH series can be used as a dividing head or for continuous movements, enabling the machining of complex operations and extending the machining range.

AHHA90 Highlights

High precision, with Harmonicdrive reduction gear as the core structure. The internal drive is a simulated engagement of multiple teeth in a symmetrical position of 180 degrees, so that the gear pitch error and the cumulative tooth pitch error have a more uniform effect on the drive accuracy, and very high positioning accuracy can be achieved.
High load capacity. Harmonicdrive transmission. Together with the number of teeth engaged at the same time, the load capacity is higher than other transmission methods. Smooth transmission, no vibrations.
The Harmonicdrive reduction gear consists of a shaft generator, a shaft gear and a spur gear, where the shaft gear is a flexible, thin-walled, elastic part with an outer ring gear that continuously deforms during ring transmission. This eliminates backlash when interacting with the spur gear and achieves high precision and low transmission backlash.
Large gear ratio. The single stage reduction ratio can reach 80-100, so you can get a large output torque.

Brakes

Pre-installed brakes with optional powerful brakes for heavy duty machining.

Weight

Small size and low weight compared to conventional gearboxes. The significant reduction in size and weight allows for a very small design. As a result, the Harmonic axis saves space on the machine and reduces the load on the table.

Transmission

Smooth transmission, low effort, no noise.
