Abstract: An apparatus comprising a cylindrical die holder base containing two recessed compartments, two different abrasive coated sharpen dies, a cylindrical index containing drill bit guide holes used to align drill bit dead center with the sharpening dies, male and female hemispheres on the index and the base to ensure alignment, a spring assembly allowing for separation of index from base while rotating index, a cylindrical safety guard used to cover index holes that are not aligned with sharpening dies, a locking knob used to lock and unlock index to base to allow or disallow rotation, and a radiused handle with a flat bottom used to safely hold drill sharpening device down on a flat surface while in use.

Abstract: A system, method, and computer program product for providing discovery services for servers during a startup sequence can include powering on a server in a domain; creating a listener socket for the server to accept coupling requests from other servers; registering server information for the server with a database; searching the database for other registered servers in the domain; establishing a couple to each of the other registered servers in the domain; and verifying validity of the couple to each of the other registered servers including performing a handshake. The server information registered with the database can include an IP address; a listener port; a domain; a version number; or a server type.

Abstract: A positioning device for a driving shaft of a lathe chuck includes a casing, a motor received in the casing with a driving shaft of the motor extending through a first end and a second end of the casing, and a disk disposed to the first end of the casing and threadedly mounted to the driving shaft. The disk has at least one hole defined therethrough and the first end of the casing has a plurality of holes defined therethrough so that a pin is removably extending through the hole in the disk and received in one of the holes in the first end of the casing to position the driving shaft to which the lathe chuck is connected.

Abstract: In connection with a device for receiving workpieces, in particular for machine tools with continuous-path control, preferably numerically controlled machine tools, a dividing mechanism having a dividing spindle, which is seated in a housing, can be brought into predetermined angular positions and is connected with a workpiece holder. It is possible to achieve an exact and rapid setting of the dividing mechanism in that it is arranged for actuation by means of a continuous-path-controlled actuator, by which an indexing mechanism associated with the dividing spindle, with whose aid the dividing spindle can be locked in place in a predeterminable angular position, can be brought into a position which releases the dividing spindle, and through which the dividing spindle can be rotated.

Abstract: In a workpiece support for use with a laser beam machine tool, in which the workpiece is rotated about an axis tiltable through 90.degree. or more to either side of a vertical condition, the workpiece is held by a chuck driven through a right-angle speed reducer by a servomotor. The chuck, reducer and motor are all supported on a shaft rotatably mounted in bearings on a frame. The shaft is coupled to a disc having angle markings and lockable at discrete rotational positions on the frame. Fine adjustment of the rotational position of the shaft relative to the disc is effected by engagement of an offset protrusion on the end of the shaft by a screw-shifted operating member on the disc. Two such operating members are provided in opposed relationship on opposite sides of the protrusion so that they can be used to lock the shaft and disc securely together.

Abstract: A machine tool comprises a spindle stock that can be moved along several axes. A work table can be rotated alternately in opposite directions by an angle of, preferably, 180.degree. about an axis extending perpendicularly to the table surface in such a manner that the halves of the table surface form alternately, at any given time, a processing area located in the working area of the spindle stock and a mounting area located at a distance from the working area. At least one line leads from a stationary part of the machine tool to the work table for transmitting signals and/or supplying energy.In order to simplify the arrangement of the line, in particular if a plurality of such lines is provided, the line is connected above the said work table to a point on the said stationary part of the said machine tool and, hanging down loosely between the two parts, on the other hand to a connection box of the said work table.

Abstract: The subject matter of the present invention is a dividing apparatus or indexing attachment for a program controlled machine tool, comprising a housing (1) including clamping means (3, 4) for attachment to a machine part, a dividing spindle (5) mounted within the housing (1) and including a work holder (8, 9) and a clamping assembly (15), and a spindle drive means including a reduction gearing, in which for achieving fully automatic sequences of operation in the manufacture of various workpieces, an opto-electronic angle measuring unit (24) and a releasable clamping means (31 to 36) are associated with the dividing spindle (5), wherein the reduction gearing includes two cylindrical gears (29, 30) having parallel axes and jointly meshing with a pinion (27) mounted on the motor shaft and further includes two pinions (46, 47) mounted on the intermediate shafts (40, 41) of said cylindrical gears, the two latter pinions meshing with the spindle drive gear (10).

Abstract: A machine tool attachment which provides for material handling, positioning, and clamping during machining and also eliminates the need for custom tool fixtures is described. The machine tool attachment mechanically advances material to be machined through a tubular tail stock and into a head stock. Collets located in the tail stock and head stock automatically power clamp the material and a rotary indexer automatically rotates and indexes the material during the machining operation. Once machining is completed, the material between the head stock and tail stock is further clamped by the attachment and then cut by the machine tool. Remaining material can then be advanced by the attachment and the process repeated. The machine tool attachment interfaces with a numerically controlled machining center which transmits signals to control the functions of the attachment for proper coordination with the machine tool.

Abstract: A work holder for precision positioning and movement of a workpiece (20) relative to a machine tool comprises a base (100), a pair of spaced stocks (200, 300) mounted on the base, a spindle assemblies (210, 310) supported on each of the stocks for rotation about a common axis, a chuck (246, 346) supported on each of the spindle assembly (210, 310) for clamping the workpiece (20) therebetween, and adjustable mounting means (236-272, 336-372) on each of the spindle assemblies (210, 310) for permitting movement of each of the chucks (246, 346) transversely of the axis. A driveshaft (406) and gearing (402, 408) is provided for imparting rotation to one spindle assembly (210). A crank (422) is operatively connected to the driveshaft (406), and oscillating drive means (416) is providing for oscillating the crank (422) about the driveshaft (406) in two opposite directions.
