A wheel reconditioning apparatus includes an upright post connected to a base seat, a transverse carrier, a first drive unit, a cutter unit, a second drive unit and a working table. The upright post has a support front surface. The transverse carrier is disposed slideably on the support front surface. The first drive unit is mounted between the upright post and the transverse carrier to move the transverse carrier. The cutter unit is disposed slideably on a carrier front surface of the transverse carrier. The second drive unit is connected between the transverse carrier and the cutter unit to drive the cutter unit. The working table is mounted to the base seat and is oriented toward the cutter unit.

A machine learning apparatus determines a control parameter of an active vibration isolation apparatus on which an industrial machine is mounted. The industrial machine includes a movable part, a drive source that drives the movable part, and a drive source control section that controls the drive source to position the movable part at a command position. The machine learning apparatus includes: an acquiring section that acquires, as teacher data, a positional deviation, which is a difference between the command position and an actual position of the movable part; a storage section that stores a learning model that outputs the control parameter corresponding to a state quantity concerning the industrial machine; and a learning section that updates the learning model using the teacher data.

Systems and methods for removing particles from a surface of a substrate without damage to the substrate are provided. The disclosed systems/methods use polymeric microstructures, e.g., microfibrils, to remove micrometric and sub-micrometric particles from a substrate surface by establishing interfacial interactions with the particles that effectively debond the particles from the surface of the substrate. The disclosed systems/methods have wide ranging applications, including particle removal in art conservation processes, microelectronic applications, optical applications and any other field that stands to benefit from precise removal of particles/dust from a surface without damage to the surface.

A device for removing circumferential burrs of a wheel with high precision includes an electric cylinder, a lifting table, guide rails, an electric cylinder, a sliding block, a plurality of sensors, a rim burr cutter, a riser burr cutter, and the like. The device can simultaneously remove circumferential burrs from the flange edge, the outer rim and the riser slot edge, which eliminates the error caused by coaxial degree deviation, so that the rotating center of the cutters coincides with the circumferential center of the burrs. The device is configured to provide high-precision removal of burrs from the flange edge, and high-precision removal of burrs from the outer rim and the riser.

An apparatus for correcting an aberration in a bullet casing's neck, the apparatus incorporating a support frame; a collet chuck and collet sleeve combination whose collet chuck presents a circumferential array of jaws having longitudinal ends, wherein the collet chuck further has a throat extending longitudinally from the jaws' longitudinal ends; a bullet ogive centering annular land fixedly attached to or formed wholly with the collet chuck, the bullet ogive centering annular land being positioned at an oppositely longitudinal end of the throat; rotatable mounting conical bearings and bushings which attach the collet chuck and collet sleeve combination to the support frame; and a turn wheel connected operatively to the collet chuck and collet sleeve combination.

A tool for machining a groove of a rotation-symmetric component, preferably a piston of an internal combustion engine, is provided. The machining is carried out by a rotation of the tool around an axis of symmetry of the rotation-symmetric component to be machined. The tool includes at least one arm disposed in such a way that a circumference of the rotation-symmetric component can at least be partially enclosed. Also, a machining device for machining of the groove is provided on the at least one arm. At least one adjusting device is provided to adjust a contact force of the at least one machining device on the rotation-symmetric component, and to adapt the tool to different diameters of the rotation-symmetric component.

The present disclosure provides a numerical control machine and a cutting method. The numerical control machine includes a workpiece seat for fixing a workpiece, a cutting tool, a non-contact measurement component for measuring a contour of a surface to be machined of the workpiece, a power component and a control component. The workpiece seat is rotatable relative to the cutting tool or the non-contact measurement component under driving of the power component, and/or the cutting tool is rotatable relative to the workpiece seat under the driving of the power component. Both the cutting tool and the non-contact measurement component are mounted on the numerical control machine, and distances from the workpiece seat to both is adjustable. The control component is electrically connected with the non-contact measurement component and the power component.

The current invention proposes sharpening thin hardened metal blades with the hard turning process using a holder designed to hold the blades in a firm and stiff manner and a ceramic cutting tool held in a fixture. Generally, the cutting tool is held stationary in its fixture while the workpiece, in its holder, is rotated such that it repeatedly comes into controlled contact with the cutting tool. In sharpening operations such as proposed here, it is critical to (i) hold the workpiece firmly and rigidly, and (ii) position the cutting tool in a precise, predictable and reliable manner.
