5C and 16C Gear-Driven Rotary Indexers

5C and 16C Gear Driven Rotary Indexers 300x300

Forkardt’s 5C and 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 Forkardt 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 capacity
