Abstract: A boring tool on a flange consisting of at least one tool holder and a flange, in which the tool holder is fitted with a means of gripping designed to engage the guiding and clamping assembly of the slide for guiding and holding the fastening flange, which is provided, in addition, with a device for limiting the travel of the tool holder or of the counterweight, or the positioning lug of a tool holder or of a counterweight can be put aside during placement a tool holder or a counterweight and returns automatically into position after this placement and in which each tool holder is fitted with a device for lubricating the cutting edge of the tool, coupled to the means of centralized lubrication of the flange. The tool is more particularly applicable in the field of numerically-controlled machine-tool accessories, tooling centers, cubicles, and flexible workshops.

Abstract: A double-sided metal drilling entry board for drilling comprises a metal bottom layer, a soft metal surface layer and a binding layer, in which the binding layer is disposed between the metal bottom layer and the soft metal surface layer to bind the metal bottom layer and the soft metal surface layer.

Abstract: Disclosed is a tap driver and tap driver system for rigid tapping, which includes a unique flexure system. In some embodiments, an integrated flexure component and housing configuration provides and may provide both a more economical and a universal configuration of the tap driver flexure component that allows the central body to be integrated with and into different types of tap drivers.

Abstract: Disclosed is a cutting tool, including: a cutting edge including a coating from a rake face to a flank face, and has a relief angle of not less than 15 degrees, a material of the coating having a higher wear resistance than a base material of the cutting edge, and during cutting of a work, an edge of the coating on the rake face at a top of the cutting edge is worn by friction with the work; with a progress of a wear inward in a radial direction, an edge of the coating on the flank face at the top of the cutting edge is removed by friction with the work to expose the base material thereunder; and the exposed base material is worn by friction with the work to retract the flank face inward in the radial direction.

Abstract: The present invention provides a system and method for tool use management wherein a CNC machine retains information identifying the tools associated with the machine as well as their current locations (if any), and executes an algorithm for determining the source tools needed by a part program and matching the source tools with the available tools.

Abstract: Machining of aluminum workpieces with diamond or diamond-like carbon-surface coated tools may be conducted in an atmosphere containing hydrogen gas at a partial pressure effective for hydrogen to react with carbon atoms at the surface to form C—H bonds that resist adherence of aluminum to the tool surface. Suitably, hydrogen or a hydrogen-containing gas mixture is confined at the interface of tool and workpieces at the machining site. Hydrogen partial pressure may be determined for a tool-workpiece-machining temperature combination by calculation or experiment.

Abstract: Hardfacing is applied on the gage surface of bit blades, the leading and trailing edges of bit blades, and on carbide inserts. The gage surface contains natural diamonds, synthetic diamonds, thermal stable polycrystalline (TSP) diamonds and carbide inserts, and the hardfacing is applied over at least a portion of them. As the primary cutters on the bit blades are worn down during drilling, the gage surface of the bit is also worn down. A hardfacing is applied to the worn gage surfaces of the bit, thereby allowing the bit to drill deeper and longer without requiring replacement.

Abstract: The present invention addresses a dredger cuttertooth manipulator that includes at least one robotic tooth handler that is adapted to remove a worn tooth from a dredger cutterhead and then replace the removed tooth with a new tooth. In a particular embodiment, the manipulator includes two robotic tooth handlers, one that removes the worn tooth, and another that replaces the removed tooth with a new tooth. The robotic tooth handler is made up of an arm and a hand that is adapted to grip the teeth.

Abstract: The present invention is directed to a drill bit with non-cutting erosion resistant inserts. In one illustrative embodiment, the apparatus comprises a matrix drill bit body comprising a plurality of blades, a plurality of cutting elements positioned on each of the blades, the cutting elements defining a plurality of web regions, and a plurality of spaced apart, non-cutting erosion resistant inserts positioned along a face of at least one of the blades, at least a portion of each of the non-cutting erosion resistant inserts being positioned in front of one of the web regions.

Abstract: The invention relates to the cutting of rotating surfaces, especially centric symmetric surfaces (1a) of a metal workpiece (1), especially one made of steel or gray cast iron, also when said workpiece is in hardened state, by means of a geometrically determined cutter (2a) or cutters, wherein the axial extension and the material of the surface to be machined are hardly limited or not limited at all and/or the operating time during machining is reduced according to said method and/or the service life of the tool is enhanced and/or the effect of the twist-free condition is achieved, wherein at least one cutter (2a) that is skewed relative to the rotational axis (10) of the workpiece is guided during a feeding motion (3,3?) in a contacting manner on the rotating workpiece and wherein the machining parameters of the rotational axis, especially the forward feed motion in the direction of feeding and the skewed position (x) of the cutter (2a) relative to the longitudinal direction (z), are chosen in such a way that

Abstract: A system is provided for removing build-up on drills. The system includes a sensing component that automatically senses the size of a drill, a first component that automatically grips the sensed drill and positioning the gripped drill to a first position, and a disc that includes a plurality of bushings of different sizes. The system also includes a second component that automatically rotates the disc according to the sensed size of the drill, and a third component that automatically forces the disc over a stationary drill.

Abstract: A bowl cutter for enlarging cylinder head valve bowls and the like that includes at least one cutting blade with first and second cutting edges. The bowl cutter further includes a body with at least one cutter mount including a clamp that securely holds the cutting blade at a preselected angular position. The cutting blade is pivotably connected to the body for angular adjustment of the cutting blade, and the clamp securely holds the cutting blade at a selected angular position wherein the first cutting edge is positioned to remove material from the base portion of an associated valve bowl, and the second cutting edge is positioned to remove material from a sidewall portion of an associated valve bowl.

Abstract: The countersink to form a conical chamfer at the mouth of a bore hole has a conical chamfering head, on which three separate cutting plates are arranged, symmetrically, the cutting plates being fastened to the chamfering head, but removable and changeable. A compatible sharpening device permits the introduction and mounting of the cutting plates, wherein the sharpening device has the same form or shape as the countersink, so that it is easy to resharpen the cutting plates to their original specifications.
