A polishing apparatus is provided with a machining head that is supported to freely move in two horizontal directions; driving devices that enables the machining head to move; a polishing jig that is supported by the machining head to freely move in a vertical direction; a polishing member that is mounted on a lower end portion of the polishing jig; an air cylinder polishing jig moving device that moves the polishing jig and is capable of pressing the polishing member against a tube support plate; and a drive motor that is capable of rotating the polishing jig, thus, simplification of the structure is made possible.

The present disclosure relates generally to a machining tool and method for using the machining tool. The machining tool includes a machining arm including a first arm section, a second arm section, a proximate end, a distal end, and a machining arm longitudinal axis, a belt disposed around the machining arm; and a first motor operably coupled to the machining arm, wherein at least a portion of the machining arm is configured to pivot such that an angle is formed between the distal end and the machining arm longitudinal axis. The method includes the steps of placing the pivotable machining arm in a first orientation, inserting the pivotable machining arm in the desired location, determining whether the belt is in a desired position relative to the raised surface, operating the motor to rotate the belt around the pivotable machining arm, and placing the belt in contact with the raised surface.

A robotic paint repair system that can comprise: a consumable abrasive product configured to abrade a substrate, a tool configured to drive the consumable abrasive product to abrade, a robotic device configured to manipulate the tool and a compliant accessory actuator positioned between the tool and the substrate, wherein the compliant accessory actuator is driven to apply a desired force and a desired stiffness to the consumable abrasive product in response to sensed data collected between the tool and the substrate

A cutting apparatus includes a chuck table for holding a workpiece thereon, a cutting unit for cutting the workpiece held on the chuck table with a cutting blade secured in place on a distal-end portion of a spindle by a mount flange mounted on the distal-end portion of the spindle, an indexing feed unit for moving the cutting unit in indexing feed directions parallel to axial directions of the spindle, a processing feed unit for moving the chuck table in processing feed directions perpendicular to the indexing feed directions, and an end face correction unit for correcting an end face of the mount flange that supports the cutting blade in contact therewith. The processing feed unit includes a table moving base that supports the chuck table thereon and an actuating mechanism for moving the table moving base. The end face correction unit is fixedly mounted on the table moving base.

A grinding- and polishing tool in combination, comprising a stave which has an edge-treatment side comprising a primary treatment area covering a part of its length, and which in the length direction of the stave is followed by an adjoining secondary treatment area covering another part of the length of the stave. The treatment areas are oriented at intersecting planes such that an intermediate angle between adjoining primary and secondary treatment areas is other than 180°. Also disclosed are a tool assembly, an attachment for a food slicer machine, and a method, all of which are unique implementations of the combined grinding- and polishing tool.

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.

An end effector for a robotic sanding system includes a sanding head including a sander configured to sand a surface of a workpiece. A motor is operatively coupled to the sander. The motor is configured to rotate the sander to sand the surface of the workpiece. The motor includes a first central longitudinal axis. A coupler is configured to removably secure the end effector to an attachment interface of an arm of the robotic sanding system. The coupler includes a second central longitudinal axis. The first central longitudinal axis is offset from the second central longitudinal axis. One or more sensors are coupled to the sanding head. The one or more sensors are configured to detect presence of a metal within the predefined range.

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 diamond special-shaped grinding wheel includes an upper base body, a lower base body, and a grinding ring. The upper base body is disposed at the upper end of the lower base body, and the upper base body and the lower base body are fixedly connected to form a grinding wheel body. The grinding ring is fixed to an outer ring of the grinding wheel body; the grinding wheel body is internally provided with one or two annular grooves communicated with the upper end face of the grinding wheel body. A plurality of mixed flow channels is formed in the grinding ring. One end of each mixed flow channel extends to an annular grinding opening of the grinding ring, the other end is communicated with one annular groove, and the annular grooves are communicated with an external negative pressure air source device. Also disclosed is a vertical machining cooling system.

A method of grinding a workpiece includes a holding step of holding the workpiece on a flat holding surface of a holding table and a grinding step of rotating a grinding wheel to turn grindstones along an annular track while rotating the holding table, and bringing the grindstones into grinding contact with an upper surface of the workpiece to thereby grind the workpiece. The grinding step includes the step of bringing the grindstones into grinding contact with the upper surface of the workpiece in a state where the annular track is closest to the holding surface in an area between a point above a center of the holding surface and a point above an outer circumferential end of the holding surface.
