Rotary Indexing Machines

Rotary indexing machines use an indexing table or waterwheel-type rotary fixture to move workpieces between multiple machining stations. Each indexed position can perform a different operation, such as drilling, tapping, boring, milling, facing, inspection, loading, or unloading.

This configuration is suitable for components that require several repeatable machining processes. By distributing individual operations across multiple stations, the machine can process several workpieces within the same production cycle. The indexing mechanism positions each fixture in front of its corresponding machining unit before the cutting process begins.

HANN KUEN drilling, tapping, boring, milling, and facing spindle units can be mounted around the rotary indexing structure according to the required machining sequence. Flange-type and compact spindle configurations are particularly useful when installation space around the indexing fixture is limited.

The machine builder should consider the number of stations, indexing direction, workpiece orientation, fixture clearance, spindle mounting position, machining time at each station, and chip or coolant management. Suitable spindle units and feeding systems can then be selected to create a coordinated rotary indexing solution.
