The 16C and 3J indexers from Hardinge have been added to the company's 5C product offering to provide rapid part positioning for all sizes, shapes and materials. Common spindle tooling can now be shared from indexer to lathe. Collets, expanding collets, step chucks and three-jaw power chucks will automatically center the part and provide grip force for heavy cutting. This collet spindle design means that gripping is in the spindle, closest to the spindle bearings, unlike surface-mounted adapters used on rotary tables.

The 16C model will accept round stock capacities up to 1 5/8" (41.27 mm), hex capacities up to 1 13/32" (35.71 mm) and square capacities up to 1 9/64" (28.97 mm). The 3J model will accept capacities of up to 1 3/4" (44.45 mm), 1 17/32 (38.89 mm) and 1 1/4" (31.75 mm) respectively.
