Hardinge Rotary Products More Accuracy, Speed and Flexibility! The Most Flexible Quick-Change Workholding Concept in 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...

Disadvantages of other Rotary Spindle Designs Hardinge Spindle Design – no collet adapter required Minimal distance from spindle bearings to tool tip Other Rotary Spindle Design – collet adapter required Other spindle designs require the use of a collet adapter creating an extreme overhang from the spindle bearings. Any error in the spindle is multiplied by the overhang distance. Excessive overhang from spindle bearings Collet Collet adapter This spindle design: • Is not rigid • Is not easily adjusted • Creates poor T.I.R. • Reduces the work envelope • Creates excessive overhang • Does not...

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...
