4th Axis NC Rotary Table

Ref: KCR

The 4th axis NC Rotary Table from Leaderdrive is based on high-precision third-harmonic turntables, with ultra-long precision to maintain life and ultra-high indexing accuracy. They are mainly used in the field of CNC high-end precision machining and manufacturing.

Our rotary table contains the world's first third-harmonic transmission system, which is adopted from Leaderdrive's own international PCT patents. It also includes our self-developed high-power-density direct-drive motors and an integrated direct connection to achieve a fast dynamic response. It is currently the only NC Rotary Table on the market with an accuracy of less than 10 arcseconds, ultra-high rigidity, and maximum clamp torque of 1470 Nm.

The structure's quality ensures that accuracy will remain unchanged for more than five years without the need for regular maintenance. Contact Leaderdrive for more information on this product, including detailed specifications and technical manuals, performance data, and pricing guides.

Product details:

High precision: The absolute positioning accuracy is within 10 arcseconds (0.0028 degrees).

Zero gap: Gapless harmonic drive.

Large torque: Small size, large torque; output torque up to 1470 Nm.

Maintenance-free: No accuracy deterioration, and no regular maintenance required. The accuracy will remain unchanged after more than 20,000 hours of use.

Integration: Highly integrated, with a built-in ultra-high-precision, high-rigidity special strain wave gear harmonic speed reducer for machine tools (PCT international patent product), and a high-power density, low cogging torque power support giant motor.

Fast response: Excellent dynamic response.

Fast positioning: No gaps and high rigidity; no need to brake when working, significantly shortening the positioning time.

High efficiency: The efficiency is as high as 75% to 80%, saving energy.
