“Back in 2008,Hardinge introduced a low-profile rotary table as a standard, no-frills unit to compete against other 210 mm tables on the market,” said Al Comstock, Rotary Product Manager at Hardinge Inc. Now, Hardinge has redesigned the model to include the Hardinge collet-ready 16C spindle that is designed to provide high-precision gripping options. The company has also extended the spindle nose for additional tooling clearance. “Part quality begins at the spindle,” said a company spokesperson. “Minimal overhang fromthe spindle bearings is intended to assure that spindle accuracy is transferred directly to the part beingmachined. Most brands of rotary tables use a collet adaptation chuck, moving the cutting several inches away from the spindle bearings. Hardinge rotary spindles are collet-ready for gripping parts of all shapes, sizes andmaterials.High-precision gripping options for the GD210LP include standard 16C collets, step chucks for larger diameters, Sure-Grip expanding collets and custom collets with the use of an optional collet closer. Special accuracy FlexC collet systems, chucks and the precision-ground faceplate (included) will mount on the A2-5 spindle. “Programmers and machine operators can expect to run higher accuracy jobs, aswell as less tooling interference, length control options, internal gripping capability, no time-consuming fixtures, lightweight alternatives for a heavy chuck, added versatility and the ability to share tooling with other machines in the shop.” TheHardinge GD210LP rotary table indexer is designed to provide rigidity, speed and repeatability. Large diameter bearings and a fail-safe clamp system allow part weight of up to 220 lbs. Radial load testing indicated a stiffness of 4x greater than a competitive model, the company said. The GD210LP uses up to 233 ft-lbs / 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 can reduce cycle time. Hardinge’s hardened and ground steel cross-axis helical gear is designed to provide long life and continued accuracy when compared to softer gears and worm gears found in other brands,” said Hardinge. “Based on true bidirectional testing, Hardinge guarantees ±15 arc-second accuracy and 10 arc-second repeatability.” The GD210LP operates with a Hardinge servo control, or it can be integrated to themachine via 4th axis. Options include a left- or right-hand motor mount, pneumatic collet closer, tailstock and a plate or cube trunnion formachining multiple parts. For smaller part production, Hardinge features the 160 mm rotary table indexer with the Hardinge collet-ready 5C spindle. For more information contact: Hardinge Inc.
