A sawing device, in particular for separating long workpiece parts, has a saw blade and a retaining device for separated workpiece parts, wherein the retaining device has a retaining element, at least on the side of the saw blade facing the workpiece part that is to be separated, which retaining element is arranged ahead of the saw blade in the machining direction of the workpiece and movably in such a way that it is movable from an inactive position above the workpiece into an active position which reaches ahead of the front end of the workpiece.

The invention relates to a speed-changing shearing or forming active element insert which is designed to be detachably connected to an active element receptacle of a machine tool, the speed-changing shearing or forming active element insert having a speed-changing unit which is in the form of a hydraulic force/distance transducer, the force/distance transducer comprising a housing, the housing interior of which is supplied with a hydraulic fluid, and the force/distance transducer comprising a first piston which is in oo contact with the hydraulic fluid via one piston end and a second piston which is in contact with the hydraulic fluid via one piston end and the cross-sectional area of which is smaller than the cross-sectional area of the first piston. The invention also relates to the use of the speed-changing changing shearing or forming active element insert in a machine tool.

The present application relates to a machining assembly comprising an effector intended to be mounted on a robot with multiple degrees of freedom, in which invention the mounting of the motor spindle relative to the intermediate supports and frame of the effector allows a numerically controlled movement along three axes X, Y, Z of a trihedron, the effector bearing on the piece to be machined or on the surrounding tools by means of a ball joint at the foot end of the effector. Since the effector bears on the piece to be machined or on the surrounding tools it is possible to create local stiffness and to obtain the precision required to guarantee the quality of the machining process.

A clamp for retaining a workpiece onto a fixture whereby the method of connecting the clamp to the fixture provides for a simultaneous combination of both horizontal and vertical clamping forces against the workpiece without locating any portion of the clamp above the upper surface of the workpiece.

A clamp apparatus includes a main frame, at least one table attachment bracket, a pair of adjustable clamping members, at least one measurement member, at least one vice attachment bracket, a catch tray and a shield member. The clamp apparatus preferably attaches to any existing drill press table, offers multiple clamping solutions for a work piece and provides a stable tabletop for the work piece.

Apparatus and methods thereof used to clamp and secure workpieces of varying shapes and dimensions into position for welding, machining, and other fabrication activities. A plurality of opposing clamping assemblies attached to the clamping table operate to move and orient separate workpieces into a desired assembly position. The oriented workpieces are then clamped and held in a fixed position for welding, machining, or other fabrication activities.

The present disclosure includes a part hold-down assembly for retaining an oversized part. The part hold-down assembly is aligned along a central force axis and applies a downward force onto the part. The part-hold down assembly includes a top plate, a bottom plate, and a compression assembly extending between the top and bottom plates. The compression assembly includes two, parallel biasing assemblies that extend along compression axes that are parallel to but offset from the central force axis. Each biasing assembly including an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The parallel biasing assemblies are positioned on opposite sides from each other about the central force axis, and may be spaced away from the central force axis an equal distance.

A clamp to retain a block of material on a machining table including a body having a first face, a first front face oriented toward the machining table and the block of material when in use, a nose projecting relative to the first front face having a second front face parallel to the first front face, first and second edges connecting the first and second front faces, and at least one internally threaded hole opening at least partly at the level of the second front face with an axis forming a non-zero angle with the first face and the second front face, at least one grub screw screwed into the internally threaded hole having a pointed free end configured to penetrate into the block of material when in use when screwing in the grub screw, and a connecting system to demountably connect the clamp to the machining table.

Three systems for the destruction of the data storage portion of electronic media storage devices such as hard disk drives, solid state drives and hybrid hard drives. One system utilizes a mill cutter with which the hard drive has relative motion in the direction of the axis of the mill cutter to destroy the data storage portion. A second system utilizes a laser to physically destroy the data storage portion. The third system utilizes a chemical solvent to chemically destroy the data storage portion.

The present concept a work piece mounting system for connecting two work elements together, includes a main body with radially oriented horizontal upper and lower jaw passageways for receiving therein upper and lower jaws respectively. The radially oriented horizontal upper and lower jaw passageways, are adapted to receive the jaws slid-ably therein, wherein the cross section of the jaws and passageways configured such that the jaws are restricted from rotating within the passageways. A vertical cavity extending vertically and centrally through the main body, along a z-axis, is for receiving a grooved end of a lower fixation element upwardly therein and a grooved end of an upper fixation element downwardly therein, wherein the other threaded end of the fixation elements are configured for detachably connecting to a working element. Wherein the jaws include a grooved portion for engaging with a grooved end of the fixation elements and are configured such that the fixation elements are drawn into the main body upon engagement of the grooved portions with the grooved ends thereby tensioning the fixation elements between the main body and a work elements. Further the angular relationship between the upper jaw passageway and the lower jaw passageway in a horizontal plane x-y relationship is selected to be able to nest the passageways to minimize a thickness T of the main body for improved rigity and dimensional stability of the work piece mounting system.
