Machine tool spindle device has tension rod displaced axially within hollow spindle head shaft via axial movement of drive shaft via displacement device

摘要

The spindle device has a drive (2) with a drive shaft (6) coupled to a spindle head (3) having a hollow spindle head shaft (11) for reception of a machining tool, with a tension rod (12) displaced axially within the hollow spindle head shaft and mechanically coupled to the drive shaft for axial movement with the latter via a displacement device. An Independent claim for an operating method for a spindle device for a machine tool is also included.
