Abstract
Multispindle lathe comprising a machine frame (12), a spindle drum (14) which is arranged in the machine frame (12), is rotatable about a spindle drum axis (16) and is made up at least partially of segments (80) which are cut out from flat material in a stacking direction (82) parallel to the spindle drum axis (16) and extend in stacking planes (88) transverse to the stacking direction (82), these segments having receiving cutouts (90) and cooling channel cutouts (92, 96, 106) which overlap with one another such that the spindle drum (14) has spindle motor receptacles (30) for spindle motors (32) and a cooling channel system (120, 130, 180) separated therefrom by wall webs (98), characterized in that the cooling channel system has several channel subsystems (120, 130, 180) for a liquid cooling medium which are fed in parallel.
Claims13
Multispindle lathe comprising
- a machine frame,
- a spindle drum arranged in the machine frame and rotatable about a spindle drum axis, said spindle drum being made up at least partially of segments cut out from flat material in a stacking direction parallel to the spindle drum axis and extending in stacking planes transverse to the stacking direction, said segments having receiving cutouts and cooling channel cutouts overlapping with one another such that the spindle drum has spindle motor receptacles for spindle motors and a cooling channel system separated therefrom by wall webs,
- the cooling channel system having several channel subsystems for a liquid cooling medium, said channel subsystems being arranged individually and independently of one another.
Multispindle lathe comprising:
- a machine frame;
- a spindle drum arranged in the machine frame and rotatable about a spindle drum axis, said spindle drum being made up at least partially of segments cut out from flat material in a stacking direction parallel to the spindle drum axis and extending in stacking planes transverse to the stacking direction, said segments having receiving cutouts and cooling channel cutouts overlapping with one another such that the spindle drum has spindle motor receptacles for spindle motors and a cooling channel system separated therefrom by wall webs;
- the cooling channel system having several channel subsystems for a liquid cooling medium, said channel subsystems being arranged individually and independently of one another;
- and
- wherein the channel subsystems are fed with liquid cooling medium through a common annular space surrounding the spindle drum.
