Abstract: A tool unit is guided by a handling unit movable in several planes for cutting out recesses or bores and de-burring the work-pieces in one operational step. A de-burring cutter is mounted in a support arm for the tool which is movable about a central axis and is engaged by two spring arrangements disposed on opposing sides of the support arm and is returned to the original position following displacement. The springs of the spring arrangement can be replaced to adjust the spring pressure to various work materials and work-pieces. The cutting angle of the tool cutter is set automatically via the pressing force. Radial movement of the cutter is possible as are resilient deflection and precise return. A spring pressure pin arrangement is provided for balancing the cutter.

Abstract: Chip enclosure (150) wherein the interior portion comprises a primary suction port (152) and a secondary suction port (154). Both primary suction port and secondary suction port are connected via a short neck portion (155) to outlet (156) that is in communication with a source of vacuum. The bulk of chips formed as a result of machining are captured by the primary suction port (152) while any remaining chips fall to the lowest location of the chip enclosure (150) where they are drawn in to the secondary suction port (154).

Abstract: A machine tool (1) has at least one but preferably two machining units (13, 14), which are assigned to two workpiece receptacles (8, 9). The machining units (13, 14) are adjustable in three axes (X, Y, Z), and they can each reach both workpiece receptacles (8, 9). The machining units (13, 14) are oriented such that their work spindles (11, 12) are in a preferably right space angle to one another. As a result, they can be moved past one another without colliding. Moreover, they can also work on the same workpiece at the same time. The workpiece receptacles are positionable independently of one another about a preferably but not necessarily common pivot axis (S). The workpieces are also rotatable about an axis (V) perpendicular to the pivot axis. This arrangement enables flexible machining of the workpieces from arbitrary directions in space.

If the insert-retaining member becomes damaged due to contact with a workpiece it can be removed from the cutting tool assembly and replaced.

Abstract: A milling tool holder comprising an elongated body adapted to be supported on a milling tool base. The body has a shank-receiving bore. A tool head supports a pair of indexable inserts, and has a shank received in the shank receiving bore to a position in which an annular face on the head faces a similar face on the body. A pair of projections on the face of the body is received in a pair of openings in the tool head to prevent the tool head from rotating with respect to the body.

Abstract: A portable boring-welding machine, in which the rotation of the tool shaft or the torch shaft and, respectively, the axial movement of the tool shaft or torch shaft in both directions are driven by a combination of only two independent motors, which can be activated from the machine control unit. The motors are housed in a box which is integral with the machine structure and has a machine carry-handle. At least the motor which drives the rotation of the tool and torch shafts is of the direct current type and is subject to the action of means which adjust its speed and operating stroke, said means being positioned, respectively, on the control unit control panel and at end of stroke means, intercepted by actuators which follow the axial movement of the tool and torch shafts.

Abstract: A machining tool for dry processing includes an encapsulated workspace having arranged therein a workpiece support which is displaceable on a machine bed. The guide members of the workpiece carrier are arranged externally of the workspace, so that chip removal is not impeded by the workpiece support guide members.

Abstract: A tool is rotated by a spindle mounted on a Z-axis table carried on a column and moved in the direction of a Z-axis to process a workpiece, while moving an X-axis table supported on a column rising from a bed in the direction of an X-axis and moving a Y-axis table supported on the X-axis table in the direction of a Y-axis to move the workpiece supported on the Y-axis. By controlling the movement of the X-axis and Y-axis tables in a contouring manner to move the workpiece along any path, holes having various sizes and shapes can be made by one type of the tool. Moreover, the wear of a cutting blade of the tool can be compensated by correcting the path of movement of the workpiece.

Abstract: A component made from a material of metal matrix composite, a so-called MMC material, is manufactured by High Speed Machining, so-called HSM machining, of a workpiece or blank of MMC material to provide a predetermined shape. HSM machining is characterized in that the cutting tool operates at a very high speed in relation to the machined work piece, especially as compared to what is normally the case when using conventional machining techniques.

Abstract: A deep drilling device suitable for drilling in workpieces, particularly crankshafts, holes at different positions and/or in different orientations relative to a work longitudinal axis, has a deep drilling unit and a work holding unit cooperating therewith. The deep drilling unit permits parallel displacements of the deep drilling tools in a horizontal X direction and a vertical Y direction, as well as a tool feed parallel to the spindle axis. The tool holding device receives one or more crankshafts in such a way that their longitudinal axis is horizontally oriented and permits a rotation about the longitudinal axis and a swivelling of the workpieces about a vertical rotary axis. As a result both different tilt angles of the holes relative to the work longitudinal axis and also different positions of the holes relative to the circumference of the workpieces can be obtained.

Abstract: The present invention discloses a roll cutter. The roll cutter has a housing. To the housing, there is attached a base, a cutter assembly, and an optional hoist assembly. The hoist assembly is a telescoping tower that allows the user to engage a roll using a hoist. The hoist can then pick up the roll and move it onto the stand. Once on the stand, the cutting assembly having a cutting tower, a cutting arm, and a saw can be placed at the desired level of cut. A saw can then be used to cut away the roll until it is the desired width. A sanding blade can be used to sand the edge of the roll.

Abstract: The tool-changing device comprises a tool carrier rotatably mounted in a basic housing by means of a hollow shaft. This tool carrier is driven via a ring motor, the rotor of which is directly connected to the hollow shaft. A servomotor for the drive of tools is provided in the interior of the hollow shaft. Furthermore, the cavity of the hollow shaft also accommodates supply lines for the tools.

Abstract: The end faces of the edge portions of a flat plate, which have been respectively cut into a given shape according to a trimming operation, are then respectively face-struck into a linear shape. Also, in the trimming operation, each of the edge portions of the flat plate is cut into a shape having a larger dimension than that of a finally required shape thereof, and the thus produced excess length portions of the edge portions are worked by compressing when a pair of semidivided cylindrical portions are butted against each other. Since a connecting portion situated between the pair of semidivided cylindrical portions is always pressed with a given pressure, the working properties of the connecting portion in the molding operation are prevented from being revived.

Abstract: A semi-automated machine for preparing double-armed sutures, i.e., a suture with a surgical needle at either end of the suture, from a bulk supply of surgical needles and an indefinite length of suture material is described. Each of the surgical needles has a suture receiving opening formed therein for receiving a suture. The machine includes a needle singulation station, a precise positioning station, a suture feeding and cutting station, a swage station, a pull-test station and an off-load station. A universal gripper mounted on a rotary indexing device automatically receives each individual needle in a predetermined orientation and conveys the needle for sequential processing from station to station to form the needle-suture assembly. A suture drawing and cutting station automatically inserts an end of the indefinite length of suture into the first of the pair of needles that form the double-armed suture.
