Automatic description (AI-Generated)

This listing features a motorized spindle manufactured by Franz Kessler, model DME 4640.6.F0S, originally designed for use with Hessap vertical lathes. The spindle is equipped with a Rexroth motor, model 1MS310B-6B-A2/S011, providing power ratings of 29 kW with voltage specifications ranging from 310 to 435 V and operating frequencies between 36 and 163 Hz. The unit includes a rotary table assembly with attached motor and various control components, including multiple control knobs and connectors mounted on a green panel.

The spindle comes with a Röhm 3-jaw chuck, type KFD-HS 250/3, featuring a full-stroke cylinder, type OVS 85, capable of operating at pressures up to 75 bar and speeds up to 8000 min⁻¹. A Balluff encoder is also mounted on the rotary table, providing position feedback for precision operations.

The housing of the spindle is rectangular metal with mounting holes on the top surface, and electrical wiring is visible connected to the housing. The chuck jaws show signs of use but appear intact, while the metal surfaces of the spindle and rotary table exhibit visible wear and some discoloration, consistent with previous use.

This motorized spindle assembly is suitable for integration into CNC lathe setups requiring a robust spindle with integrated control and feedback components. Two units are available in stock.
