TH Series

Harmonic Roatry Table – THE CHEAP SOLUTION

TH series is a CNC rotary table driven by Harmonic Drive gear, which is popularly used as a convenient positioning unit or as a fourth axis in CNC machine tools. For example, it can be installed parallel to the X-axis, Y-axis or Z-axis of the machine tool to add a rotary axis to the machine. Siemens and Bosch-Rexroth are available as drives. The TH series can be used as a dividing head or for continuous movements, enabling the machining of complex curved surfaces and extending the machining range.

TH170-135 Highlights

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.
Pre-installed brakes with optional powerful brakes for heavy duty machining.
Smooth transmission, low effort, no noise.

Harmonicdrive

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 a very high positioning accuracy can be achieved.

Size

Small sizes and low weight compared to conventional gearboxes. The significant reduction in sizes 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.

Gear ratio

The single-stage gear ratio can reach 80-100, so you can achieve a large output torque.
