A sander apparatus for use with a drill press having a chuck defining a drill chuck axis. The sander apparatus includes a base assembly and a sander assembly supported by the base assembly, the base assembly locating the sander assembly in a predetermined location relative to the drill press chuck, in which a central pin axis of the sander assembly is aligned with the drill chuck axis. When a portion of an upper shaft of the sander assembly is secured in the chuck, rotation of the chuck about the drill chuck axis causes corresponding rotation of a body element of the sander assembly about the central pin axis. The base assembly supports the sander assembly in the predetermined location thereof as a workpiece is engaged with one or more abrasive elements on the body element while the body element rotates about the central pin axis.

A grinding robot for grinding an electrically conducting workpiece. The grinding robot includes a grinding wheel, an actuation device for actuating grinding wheel, and a control system. The grinding wheel including an undulated tool receptacle which defines an axis of rotation about which the grinding wheel can rotate during grinding, and a head which is rotationally symmetrical with respect to the axis of rotation, and which contains abrasive material and has a grinding surface which is in contact with workpiece during grinding. The grinding wheel also includes a measuring and transmission unit and at least one conductor strand pair with two conductor strands which are electrically insulated from one another. The conductor strands are embedded in the rotationally symmetrical head and extend from the grinding surface of the head into the interior of the head and are electrically connected with measuring and transmission unit.

A multi-axis polishing apparatus includes a machine body, a multi-axis transmission device, and an abrasive container set. The multi-axis transmission device, movably mounted onto a main vertical column in a machine body that can move in an insertion direction, includes a driving module and a plurality of shaft assemblies connected transmissively to the driving module. The plurality of shaft assemblies is used to mount a plurality of workpieces, respectively. The abrasive container set, located below the multi-axis transmission device, is filled with abrasive materials. The multi-axis transmission device moves in the insertion direction to position the plurality of shaft assemblies as well as the plurality of workpieces downward into the abrasive container set, and then the driving module rotates the plurality of shaft assemblies and the plurality of workpieces to utilize the abrasive materials to polish the plurality of workpieces.

A tool for chamfering cleaved tips of optical fibers. The tool including conical bores of relatively smooth and hard material terminate at a cylindrical bore that is slightly larger than the fiber core maximum diameter and a fiber centering bore that is slightly larger than the fiber coating maximum diameter. The tool provided such that when a cleaved fiber tip is inserted into the centering bore the sharp edge falls upon the chamfering surface that, when rotated relative to the fiber, gently grinds the edge to the chamfer angle. Chamfering cannot occur on the core face due to the absence of tool surface at this dimension.

The invention relates to a machine tool for robot-assisted surface finishing. According to one embodiment, the machine tool comprises a first support plate and a second support plate. The first support plate is designed for mounting on a manipulator. An output shaft for receiving a rotatable tool is mounted on the second support plate. The machine tool additionally comprises a linear actuator that acts between the first support plate and the second support plate, as well as a motor which is mounted on the first support plate. The machine tool additionally comprises a telescopic shaft with a first shaft portion and a second shaft portion that can be displaced relative to said first shaft portion. The first shaft portion is coupled to a motor shaft of the motor, and the second shaft portion as mounted on the second support plate. The telescopic shaft is coupled to the output shaft by means of a gear mechanism.

A grinding machine, includes a pivotable tool spindle with a workpiece spindle adapted to receive a gearwheel workpiece and for rotationally driving the gearwheel workpiece about a workpiece spindle axis, wherein the tool spindle is configured to receive a grinding tool and rotationally drive the grinding tool about a tool spindle axis, and is carried by a pivot axis in such a way that the tool spindle together with the grinding tool can be pivoted about the pivot axis, and wherein the pivot axis (A) intersects the workpiece spindle axis (C) in a common plane projection, and wherein the pivot axis is offset laterally relative to the workpiece spindle axis and does not intersect the workpiece spindle axis.

A coating removal apparatus includes multiple pairs of rotatable brushes spaced apart from each other in a first direction. Each pair of brushes may include two opposing brushes that are configured to rotate about a common axis and move towards and away from each other in a second direction transverse to the first direction. When a coated panel is positioned between the two opposing brushes, first portions of the brushes may separably engage with and rotate on opposite surfaces of the coated panel. The apparatus may also include one or more liquid tanks configured to contain a liquid. When the tanks contain the liquid and when the coated panel is positioned between the two opposing brushes, second portions of the two brushes may at least contact the liquid in the liquid tanks.

In one embodiment, a polishing head includes an elastic film configured to form pressure rooms to which a pressure fluid is fed, and configured to press a substrate onto a polishing surface with a fluid pressure of the pressure fluid. The head further includes a first magnetic generator provided above a partition wall that separates the pressure rooms. The head further includes a second magnetic generator configured to form at least a portion of the partition wall or provided below the partition wall.
