This Index MS 25 E is a multi-spindle lathe — sometimes referred to as a multi-spindle automatic — designed for high-productivity turned-parts production. Multi-spindle lathes of this type perform simultaneous machining operations across multiple workstations in a single cycle, making them well suited to the volume production of precision components from bar stock. Index is a German machine tool manufacturer with a long-standing reputation for precision turning and multi-spindle technology, serving industries such as automotive, aerospace, and general engineering.
This machine is equipped with six spindles, each supported by its own dedicated cross slide and longitudinal slide, allowing independent tooling operations to be carried out simultaneously at every station. The spindle bore passage measures 27 mm, and the machine accepts round bar stock up to that diameter, hexagonal material up to 24 mm across flats, and square material up to 18 mm. Turning length reaches 59 mm. Cross slide travel is 36 mm and longitudinal slide travel is 85 mm, defining the working envelope available at each station.
The spindle speed range runs from 366 to 5,020 rpm, giving the machine considerable flexibility across a wide variety of materials and cutting conditions. Maximum torque is rated at 95 Nm, and total power consumption is 20 kW. The control system is an Index proprietary unit.
The machine is fitted with a polygon device and a thread cutting device, extending its capability beyond plain turning to include polygonal forms and threaded features. A hydraulic tapping device is also installed. Finished components are handled by an integrated workpiece removal belt, supporting uninterrupted production flow. Bar stock is fed automatically via a Pietro Cucchi bar loading magazine, model AN-BN, enabling extended unmanned running.
Included with the machine are various tool holders, various collets, a chip conveyor, and a coolant system. This 1998 machine is offered used and is located in Germany.
