Low-Profile Rotary Table

Hardinge Workholding’s GD210LP low-profile rotary table provides rigidity, speed, accuracy and repeatability in an affordable package, the company says. It is designed with high stiffness and rigidity, large-diameter bearings and a fail-safe clamp system allowing part weight of much as 220 lbs. The rotary table 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.

Hardinge Workholding’s GD210LP low-profile rotary table provides rigidity, speed, accuracy and repeatability in an affordable package, the company says. It is designed with high stiffness and rigidity, large-diameter bearings and a fail-safe clamp system allowing part weight of much as 220 lbs. The rotary table 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. A fast clamp and release in milliseconds reduces cycle time. The hardened and ground steel cross-axis helical gear is designed to provide 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 faceplate 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 fourth axis directly 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.

The company guarantees ±15 arcsecond accuracy and ±3 arcsecond repeatability based on 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.
