A system for repairing dovetail slots includes a slot adaptor having a body configured and disposed to nest between first and second side walls of a dovetail slot, and a tool holder configured to be coupled with the slot adaptor. The tool holder includes a tool guidance system configured and disposed to direct a tool into contact with one of the first and second side walls of the dovetail slot. A cutting tool is mounted in the tool holder. The cutting tool includes a tapered surface configured and disposed to form a tapered recess in the one of the first and second side walls of the dovetail slot.

A material-removing machine for removing material from a cone section of a medical balloon includes a material-removing element operatively connected to a prime mover such that operation of the prime mover imparts rotation to the material-removing element about a rotational axis. The material-removing element includes an interior surface defining a generally conical-shaped cavity extending along the rotational axis and adapted to receive at least a longitudinal portion of a cone section of an expanded medical balloon for removing material from the longitudinal portion of the cone section to reduce a wall thickness of the cone section. Material may be removed continuously around a 360-degree exterior perimeter of the longitudinal portion of the cone section of the medical balloon to reduce the thickness of the balloon wall defining the cone section.

Provided is a method for manufacturing a gripping tool for gripping a workpiece with top jaws (30) attached to a plurality of master jaws (20) attached to a gripping tool body (10). A first positioner (21, 24) that determines the distance of the top jaw from the center axis of the top jaw when the top jaw is attached to the master jaw is formed in a direction perpendicular to a slide direction in a surface of the master jaw. The method includes a step of attaching the plurality of master jaws to the gripping tool body, a step of gripping a shaping plug (70) by sliding the plurality of master jaws toward the center axis, and a step of finishing, in the surface of the master jaw, the first positioner extending in the direction perpendicular to the slide direction.

A method for clamping a tool on a tool spindle in a hard finishing machine that includes: the tool spindle connected to a drive motor, with a cylindrical receiving seat and a thread, and the tool. The receiving seat is limited at one axial position of the tool spindle by a abutment flange for axial abutment of the tool. A clamping nut can be screwed onto the thread and is designed for axial abutment on the tool. The clamping nut is temporarily held in a rotationally fixed manner when the tool spindle is rotated by the drive motor. The method includes: placing the tool on the receiving seat and screwing the clamping nut onto the thread; blocking the clamping nut against rotation during the rotation of the tool spindle with the drive motor; and actuating the drive motor to tighten the clamping nut so it presses axially against the tool.

The present application includes methods, apparatuses, and systems for cleaning an aluminum wheel. In particular instances, a method of treating an exterior surface of an aluminum vehicle wheel comprising: blasting the exterior surface a first occurrence for a first duration at a first velocity using blasting media; blasting the exterior surface a second occurrence for a second duration at a second velocity using blasting media after blasting the exterior surface for a first duration, the second velocity being substantially lower than the first velocity; and, arranging the vehicle wheel in contact with vibratory finishing media and vibrating the vehicle wheel with the vibratory finishing media for a duration after blasting the exterior surface in each of the first and second occurrences.

A method for machining small rotary cutting tools by a grinding machine, comprising: a) mounting a workpiece in a spindle of the grinding machine; b) machining a calibration portion of the workpiece by performing one or a plurality of marks on said workpiece with one abrasive wheel or with a corresponding plurality of abrasive wheels of different shapes, wherein said one mark or each mark comprises at least one geometrical feature and two position features corresponding respectively to a geometrical feature and to 3D coordinates of the corresponding abrasive wheel, in a X-Y-Z coordinate system of the grinding machine, that has ground the corresponding mark c) performing measurements of said at least one geometrical feature and said two position features of said one mark or each mark of the calibration portion d) generating a sequence of instructions based on said at least one geometrical feature and on said two position features of said one mark or each mark as measured under step c) to grind said workpiece to the final and desired shape of the cutting tool and e) controlling the 3D coordinates of said one or more abrasive wheels in said X-Y Z coordinate system during grinding operations on the workpiece or on another workpiece according to said sequence of instructions to obtain said cutting tool.
