An edge plate removal system includes a frame, a set of alignment rods attached to the frame, a set of clamping assemblies attached to the frame, a handle attached to the frame, and a set of lift points attached to the frame. Each alignment rod, of the set of alignment rods, is configured to be inserted into a bore of an edge plate (e.g., a cutting edge) of an implement (e.g., a blade) of a machine. Each clamping assembly, of the set of clamping assemblies, is configured to clamp the edge plate and includes a first clamp and a second clamp, a clamp rod, a set of retention nuts, and a set of tightening nuts. The handle and the set of lift points are configured to facilitate application of a pulling force on the edge plate when the edge plate is clamped by the clamping assembly.

The present invention discloses an machining device based on a portable 5-DOF parallel module. The machining device based on a portable 5-DOF parallel module comprises: a table for moving a parallel module to increase the stroke of the machine tool such that the machine tool can machine large components and can also simultaneously conduct the mounting and the machining of workpieces at different stations; a CNC rotary table; and a portable 5-DOF parallel module. The portable parallel module has a large swing angle range, can conduct the conversion between vertical and horizontal machining modes and can achieve five-face machining in one setup in cooperation with the CNC rotary table. The parallel module can move flexibly, and can machine large and complex components after mounted on the sliding table. After the machining of the workpiece is completed, the parallel module can move to the position of a mounted component through the table to conduct the machining of the next component. Thus, the mounting and the machining of the workpiece are simultaneously conducted at different stations, and the utilization rate and the production efficiency of the portable parallel module are improved.

A pretensionable locking system, a method for producing a locking system and a medical-technical instrument including a locking system. The locking system (2) includes a locking body (10) with an inner thread (12), and an inner locking body (20) with an outer thread (22). In a pretensioned position, the inner thread lies against the outer thread in a first longitudinal axial direction (80) and is pretensioned against the outer thread. In a locked position, the outer locking body is fixed on the inner locking body by screwing the inner thread onto the outer thread. The outer locking body has a resilient retaining element (14) that projects radially inward, and the inner locking body has a rigid bulge (24) that projects radially outward. In the pretensioned position, the retaining element lies against the bulge in a second longitudinal axial direction (85) that is opposite the first longitudinal axial direction.

A method of transporting a workpiece includes steps of: (a) adjusting an inclination of a stage including a placement surface on which the workpiece is to be placed such that the placement surface is inclined with respect to a horizontal plane; (b) receiving the workpiece from a transport apparatus configured to transport the workpiece by raising lift pins provided in the stage, before or after step (a); (c) placing the workpiece on the inclined placement surface by performing at least one of lowering the lift pins and raising the stage; and (d) adjusting the inclination of the stage such that the placement surface on which the workpiece is placed is parallel to the horizontal plane.

A machining unit for machining, in particular turning and/or milling, workpieces, in particular elongate workpieces, in particular shafts, includes a machining tool. The machining tool can be moved along at least two different, in particular combined, motion paths in a motion plane. The machining until also includes at least one drive unit, which is designed for moving the machining tool along a first motion path and along a second motion path, which is different from the first motion path, possibly in a combined manner.

A machine tool includes a headstock that holds a workpiece, a tool post that is movable in a first axis direction parallel to a workpiece rotation axis and in a second axis direction orthogonal to the first axis and holds a tool, an in-machine robot, an opening for communicating the inside and the outside of a working chamber, and a door that opens and closes the opening. The robot includes a root joint fixed in the working chamber and a link unit positioned on a distal end side of the root joint. The root joint is a linear-motion joint extendable in a direction orthogonal to the workpiece rotation axis, and is a linear-motion joint extendable between the length for causing the entire link unit to be positioned inside the working chamber and the length for causing the entire link unit to be positioned outside the working chamber.
