Rotary Table features low-profile design.
September 23, 2008 -
With large diameter bearings and fail-safe clamp system, Model GD210LP allows part weights up to 220 lb. Table has 210 mm precision ground slotted face plate, offers rotation up to 40 rpm, and uses up to 233 lb-ft of clamping torque to handle off-center drilling, cross-axis milling, and other high-force cutting applications. Operated as standalone unit or as true 4th axis direct connected to machine, table provides ±15 arc-sec accuracy and ±3 arc-sec repeatability.

Hardinge Introduces A Rigid, Low-Profile Rotary Table
Hardinge's new GD210LP low-profile rotary table provides rigidity, speed, accuracy and repeatability in an affordable package. High stiffness and super rigidity are accomplished with large diameter bearings and a fail-safe clamp system allowing part weight of up to 220 pounds. Radial load testing indicated a stiffness of 4x greater than a competitive model. The GD210LP uses up to 233ft-lb/315Nm of clamping torque to handle off-center drilling, cross-axis milling and other high-force cutting applications. A fast clamp and release in milliseconds reduces cycle time. Hardinge'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 Hardinge GD210LP has a 210mm slotted face plate that is precision ground on a Kellenberger® grinding machine and features rapid table rotation of up to 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 true 4th axis direct connected 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.
Hardinge guarantees ±15 arc-sec accuracy and ±3 arc-sec repeatability based on true bidirectional testing. Double eccentrics design (not single) provide for the finest possible gear mesh from the factory. Customers can perform future gear wear compensation for extended life and improved accuracy over time. Units will be available for delivery in December 2008. For more information call 800-510-3161.
The Hardinge Group also includes Bridgeport, Hauser, Kellenberger, Tripet, and Tschudin brands. Founded nearly 120 years ago, Hardinge is a global leader in providing turning, milling, grinding and workholding solutions to meet a wide array of market needs. The company's common stock trades on NASDAQ under the symbol HDNG, and is headquartered in Elmira, New York.
