Indexing/rotary table system for larger workpieces

The 16C indexing/rotary table system is an extension of the successful 5C system launched by Hardinge last year. It is designed to provide the same performance and capabilities as the 5C but on larger and heavier workpieces. The 16C model will accept ‘round stock’ capacities up to (41.27 mm), hexagon capacities up to (35.71 mm) and square capacities up to (28.97 mm) - using standard collets. The system has a 152.4 mm centreline to base capacity – and a 41.2 mm through-hole-capability (for longer parts). A pneumatic collet closer provides 2068 kg draw bar pull. And the 16C’s 15.87 mm stroke allows the use of "power" chucks. The 16C system provides users with rapid part positioning and enables a diverse range of milling operations (spiral, linear, arc etc) on large, complex components to be undertaken – and has been aimed at customers machining, amongst other components, higher-precision medical and aerospace parts. The system enables common and standard spindle tooling to be shared – from indexer to lathe - and can be mounted directly and quickly in or on the (A2-5) spindle without the use of an adapter. Collet, expanding collets, step chucks and 3-jaw power chucks automatically centre the part and, because the collet spindle design means that gripping is in the spindle - closer to the spindle bearings - superior gripping force required for heavy cutting is produced.
