Electric drive for a machining unit on a machine tool or a machining center, has a first motor device to move the machining tool and a spring structure in a load-relieving device

摘要

A first motor device (10) moves a machining tool along a machining axis (A). Supported on a pier with its supporting position adjusted by an adjusting device (21-25) and on a spindle drive's spindle nut (26), a spring structure (27) in a load-relieving device (20) supports a machining unit or parts of the first motor device linked to the machining unit. The spindle drive's spindle links to a second electric motor (21) via a belt drive (22-24). An independent claim is also included for a control method for an electric drive for a machining unit.
