ELECTRIC SPINDLE FOR NUMERICAL CONTROL MACHINES
专利汇可以提供ELECTRIC SPINDLE FOR NUMERICAL CONTROL MACHINES专利检索，专利查询，专利分析的服务。并且Electric spindle (1) for numerical control machines structured to lock and rotationally drive a tool (100) about a predetermined reference axis (A) locally coinciding with the longitudinal axis of the tool (2); the electric spindle (1) comprising: an outer structural casing (2) that is structured to be rigidly attachable to a generic numerical control machine; an electric motor (3) that is housed within the structural casing (2) and is provided with a drive shaft (4), which projects/emerges with its front end (4a) outside the structural casing (2) while remaining locally coaxial to the reference axis (A) of the electric spindle; a rotating thrust- bearing bushing or sleeve (11), which is fitted in an axially rotatable manner on the front end (4a) of the drive shaft (4) via interposition of a first set of annular rolling bearings (12), and is maintained coaxial to the reference axis (A) of the electric spindle by a second set of annular rolling bearings (13), which are interposed between the rotating bushing or sleeve (11) and the structural casing (2); and at least one disassemblable tool-holder head (5, 5') that is structured to be attachable, in a rigid and stable though easily releasable manner, to the front end (4a) of the drive shaft (4), is structured so as to accommodate and retain, in a rigid and stable though easily releasable manner, the shank (101) of a generic tool (100) for numerical control machines, and is provided with a peripheral crown (14) that is dimensioned/structured to stably abut, selectively and alternatively, on the front end (4a) of the drive shaft (4) or on the rotating thrust-bearing bushing or sleeve (11).，下面是ELECTRIC SPINDLE FOR NUMERICAL CONTROL MACHINES专利的具体信息内容。
