Hardinge Rotary Products More Accuracy, Speed and Flexibility! The Most Flexible Quick-Change Workholding Concept on the Market… Hardinge’s A2-4 (5C) and A2-5 (16C) spindle nose designs allow quick change between collets, expanding collets, step chucks, 3-jaw chucks and face plates. Common spindle tooling can be shared between the Hardinge Rotary System(s) and a lathe. The gripping is in the spindle, closest to the spindle bearings, unlike surface-mounted adapters used on traditional rotary tables. Multiple workholding options provide alternate gripping solutions for increased precision and capability....

Interfacing to a Host Machine True 4th-Axis* via the host machine (gear-driven) Hardinge gear-driven rotary systems may be connected directly to the host machine and its CNC control. Connecting to the machine's CNC control requires replacing the standard servo motor and cable with a servo motor and cable that is compatible with the host CNC. If the machine is not 4th-axis ready, the machine will need a 4th-axis option and servo amplifier installed. Hardinge has integrated its rotary products with Fanuc, Siemens, Heidenhain, Okuma and Milltronics. Other systems can be supported with the assistance...
