Rigid, Low-Profile Rotary Table

Hardinge’s GD210LP low-profile rotary table provides rigidity, speed, accuracy and repeatability. High stiffness and super rigidity are accomplished with large-diameter bearings and a fail-safe clamp system allowing part weight of more than 220 lbs. Radial load testing indicated a stiffness of 4 times greater than a competitive model, the company says.

Hardinge’s GD210LP low-profile rotary table provides rigidity, speed, accuracy and repeatability. High stiffness and super rigidity are accomplished with large-diameter bearings and a fail-safe clamp system allowing part weight of more than 220 lbs. Radial load testing indicated a stiffness of 4 times greater than a competitive model, the company says. The GD210LP uses as much as 233 foot pounds/315 Nm of clamping torque to handle off-center drilling, cross-axis milling and other high-force cutting applications. The company’s hardened and ground steel cross-axis helical gear provides much longer life and continued accuracy when compared to softer gears and worm gears found in other models.

 

The rotary table has a 210-mm slotted face plate that is precision ground on a Kellenberger grinding machine and features rapid table rotation of as much as 40 rpm. The face plate can be removed to mount a manual jaw chuck directly to the A2-5 spindle for ease of gripping round parts. The rotary table can be operated as a standalone unit (horizontal or vertical) with a servo control, or as a fourth-axis direct connect to the machine. The low-profile footprint takes up minimal space on the table allowing vises or other fixtures to remain in place for other jobs reducing setup and teardown.

 

The company guarantees ± 15-arcsecond accuracy and ±3-arcsecond repeatability based on true bidirectional testing. Double eccentrics design (not single) provide for the finest possible gear mesh from the factory, the company says. Customers can perform future gear wear compensation for extended life and improved accuracy over time.
