082142000 | Headstock | 11 |
20110056343 | MACHINE TOOL - In a machine tool, a support member to which a headstock is mounted movably in an upward-downward direction is movable so as to change a position thereof in a horizontal direction relative to that of a bed. A guide member is provided on the bed and configured to guide the support member. An engageable portion at which the support member is supported by the guide member is located in the support member at a level within a range of upward-downward movement of the headstock along the support member. | 03-10-2011 |

20100199817 | METHOD OF MACHINING A CARRIER ASSEMBLY - A method for machining a surface on a workpiece having a member extending perpendicularly to the surface includes determining a position of a tool, determining a position of the workpiece, positioning at least one of the workpiece and the tool to a predefined position, rotating the workpiece, and rotating the tool to a predefined rotational speed. The predefined rotational speed synchronizes the rotation of the tool with the rotation of the workpiece in order to avoid unwanted contact between the tool and the member. The method includes the steps of translating at least one of the tool and the workpiece in a direction parallel to an axis defined by the workpiece, removing material from a first portion of the workpiece, translating at least one of the tool and the workpiece in a direction perpendicular to the axis of the workpiece, and removing material from a second portion of the workpiece. | 08-12-2010 |
20110179918 | Lathe - In order to improve a lathe comprising a machine frame, a workpiece spindle unit arranged on the machine frame and having a workpiece spindle housing and a workpiece spindle rotatingly drivable about a workpiece spindle axis in the workpiece spindle housing, a supporting unit which is arranged on the machine frame and in which a workpiece receptacle rotatable about the workpiece spindle axis can be supported on the machine frame radially to the workpiece spindle axis, in such a manner that rotary machining operations other than longitudinal turning are possible in a simple manner it is suggested that the supporting unit have a bearing member receptacle, in which a guide bushing for longitudinal turning can be supported in the area of its workpiece receptacle in a longitudinal turning version of the lathe and the workpiece spindle unit can be supported in the area of its workpiece receptacle radially to the workpiece spindle axis in a short turning version of the lathe. | 07-28-2011 |

20150101467 | BEARING ASSEMBLY FOR USE WITH A ROTATING MACHINING DEVICE - A rotating machining device includes a segmented support housing arranged to be mounted on a work piece and a segmented headstock mounted on the support housing and rotatable relative to the support housing about an axis. The rotating machining device also includes at least one bearing assembly disposed between the headstock and the support housing. The at least one bearing assembly includes a first race having a first set of bearing elements arranged to dynamically contact a first portion of the headstock and reciprocate within the bearing assembly in a first direction. The at least one bearing assembly also includes a second race having a second set of bearing elements arranged to dynamically contact a second portion of the headstock and recirculate within the bearing assembly in a second direction opposite the first direction so as to promote distribution of a load applied to the bearing assembly. | 04-16-2015 |
