20140371042 | TOOL MAGAZINE SHELF - An embodiment of a circular, annular tool magazine shelf of a tower construction, comprises a base frame adapted for receiving a tool shelf which has a plurality of immovable tool deposit plates, arranged in vertical succession and in a circular ring, adapted for machining one or more tools, and a power-driven tool handling system adapted for transporting tools between the tool magazine shelf and a machine-side pick-up tool magazine store. The magazine shelf also comprises a spindle tower which is mounted rotatably about a vertical rotation shaft being arranged in a circle centre-point of one or more tool deposit plates, wherein the base frame includes a monolithically constructed, plate-shaped foundation in which the rotation shaft is mounted overhanging freely by way of a mounting arrangement. | 12-18-2014 |
20140301800 | TOOL SPINDLE - An embodiment includes a two-part power-driven tool spindle that comprises a spindle motor housing in which a first liquid cooling duct extends, a spindle head housing in which a second liquid cooling duct extends, the first and second liquid cooling ducts forming a liquid cooling circuit for a coolant, and a liquid duct, through which the coolant can be conveyed out of the liquid cooling circuit to at least one resealable outlet opening in the spindle head housing and/or in the spindle motor housing. The liquid duct branches off from the second liquid cooling duct in the spindle head housing and/or from the first liquid cooling duct in the spindle motor housing, in such a way that the coolant in the spindle motor housing and the coolant in the spindle head housing can flow out of the tool spindle under gravity. | 10-09-2014 |
20140274627 | VERTICAL MACHINING CENTRE IN GANTRY CONSTRUCTION - A vertical machining centre in gantry construction may comprise a machine frame having two side walls configured to receive a tool-carrying assembly and a workpiece-carrying assembly, a moveable pickup tool magazine store within the two side walls of the machine frame configured for a tool change by the pickup method, and a machine enclosure which completely encloses the machining centre. Below the moveable pickup tool magazine store there may be a free space in which there is additionally at least one further spare magazine, equivalent in construction to the pickup tool magazine store. A force-driven reloading handling system, with which machining tools can be reloaded from the spare magazine into the pickup tool magazine store and vice versa, may be provided within the machine enclosure at an access opening of the machine frame. | 09-18-2014 |
20090283950 | MACHINING CENTER WITH A ROTATABLE AND PIVOTABLE WORKPIECE TABLE HAVING A CLAMPING DEVICE FOR THE ROTATION AXIS - A machining center that includes a swivel bridge supported by a bearing wall and pivotable about a horizontal axis, at least one drive sprocket attached to a disc-type connector of the swivel bridge, and at least one drive system attached adjacent the bearing wall and operatively connected to the drive sprocket of the swivel bridge. The machining center is characterized by clamping of the swivel bridge being performed by a friction-locked clamping system which is arranged rotationally fixed about a bearing pin of the swivel bridge in a circular ring shape and which is operatively connected to the disc-type connector. A clamping force of the friction-locked clamping system is generated by an energy storage. | 11-19-2009 |
