Abstract:
The invention relates to a device for use in production of bevel gears. The device comprises a turning machine (22), with a working spindle (22.1) and a counter-holder (23), arranged co-axially to a rotational axis (B1) of the working spindle (22.1) for the coaxial tensioning of a workpiece blank (K1). A multi-functional tool holder (24) is provided, which may be displaced relative to the workpiece blank (K1) held in the turning machine (22) and comprises a tool base (25) mounted to rotate about an axis (B2). The tool base (25) is provided for fixing one or more tools. A tool housing (26) with milling head (27) is provided, the tool housing (26) being displaceable relative to the workpiece blank (K1) held in the turning machine (22) and the milling head (27) is mounted to rotate about a milling head axis (B3). A controller is provided for control of the movement processes, to subject the workpiece blank (K1) firstly to a turning process with a tool fixed to the tool base (25) and then a toothing machining with the milling head (27).
Abstract:
Disclosed is to a composite material, a structural element comprised of the composite material, an airplane wing spar and their methods of production. Some embodiments of the present invention include composite materials comprised of multiple layers of arrays of metallic bodies separated by layers of non-metallic material, wherein the orientation of metallic bodies in some metallic layers is structurally complementing to the orientation of metallic layers in adjacent metallic layers. Other embodiments of the present invention include structural elements, such as an airplane wing spar, comprised of the composite material.
Abstract:
Apparatus for machining parts, such as pistons, comprising a main spindle having an axis, a tool holding head movably mounted on one end of the spindle, a plurality of tools mounted in a circular formation on the head at positions spaced radially outwardly from the axis and a cross slide for moving the head transversely of the axis so that the tools thereon are movable between concentric and eccentric positions relative to the spindle axis. When the tools are in their concentric positions, a workpiece can be centered on the spindle axis in a clearance relation with the tools. When the cross slide is actuated to move the tool head toward the eccentric position, one of the tools is moved into machining engagement with the workpiece. The tool head is rotatable on the spindle to index the tools and is readily removable from the spindle for tool replacement purposes.
