摘要： A push stop (100) for use in a slot disposed in a worksurface includes: a body (102), a resilient element (104), and an anchor assembly (106). The anchor assembly is configured to anchor a first portion (110) of the body in a fixed anchored position within the slot. A resilient force exerted by the resilient element urges a second portion (114) of the body into a fixed raised position in which the second portion protrudes beyond the worksurface. When an external force sufficient to overcome the resilient force is applied, the resilient element yields until none of the second portion protrudes beyond the worksurface.

摘要： A method and a device for machining a workpiece rotating about a rotational axis. The machining point moves along the cutting edge of a cutting edge plane and the surface to be machined in a rolling movement on an advancement plane not intersected by the rotational axis. A pivot drive implements a large enough pivot angle so that a first workpiece surface is machined by a machining point moving along the first cutting edge in a first machining step. In a second machining step, a second workpiece surface is machined, wherein the machining point moves along the second cutting edge and the second workpiece surface. The cutting edge has a curvature radius smaller than the distance from the pivot axis of the holder to the cutting edge. The holder can additionally be displaced on the advancement plane with a movement component in a direction transverse to the rotational axis.

摘要： A workpiece change for use in a machine tool that comprises a tool spindle for clamping tools for machining workpieces, comprises two wheels arranged parallel to one another and rotatable about an axis of rotation into at least two prominent angular positions. Two swivel tables for clamping workpieces are arranged between the wheels and are each mounted on the wheels to swivel about a swivel axis which runs parallel to the axis of rotation. In each prominent angular position, one of the swivel tables is located in its working position in which clamped workpieces can be machined with the tools. Both wheels are supported at their rim.

摘要： In a method and a device for machining an elongate workpiece that is not rotationally symmetrical in the form of turbine blades, the workpiece is supported by a steady rest that has clamping elements for clamping the workpiece on the cross-section thereof that is not rotationally symmetrical. After clamping the workpiece, the steady rest moves with its open clamping elements along the longitudinal axis of the workpiece into a supporting position. During movement of the steady rest into the supporting position and/or while the supporting position of the steady rest is being changed, a collision between the open clamping elements of the steady rest and the workpiece is prevented by a program-controlled rotation of a rotary part of the steady rest.

摘要： A machine tool that enables a reduction in the amount of deflection of a swiveling table is provided. A machine tool includes a base, a swiveling table that is shaped to be elongate and that swivels while sliding on an upper surface of the base, and an actuator attached to a longitudinal first end of the swiveling table to move a position of the first end of the swiveling table with respect to the base, thereby adjusting a swiveling angle of the swiveling table with respect to the base. The rigidity of the swiveling table against a bending force that bends the swiveling table in a deformed manner in a swiveling plane is set to increase from the longitudinal first end of the swiveling table toward the swiveling center.

摘要： A machining apparatus has a machine frame having a vertical front wall and a pair of vertical side walls extending generally perpendicularly rearwardly from the front wall and a cross slide vertically displaceable on the front wall. A first holder is horizontally displaceable on the cross slide, and respective carriages horizontally displaceable generally perpendicular to the front wall on the side walls carry a mount between and pivotal in the carriages about a horizontal axis generally parallel to the front wall. A second holder is carried on the mount. One of the holders is adapted to hold and rotate a workpiece and the other of the holders to hold a tool. A drive is connected to both of the carriages for synchronously displacing same and thereby aligning the workpiece in the one holder with the tool in the other holder.
