A machined wheel post-processing equipment includes a wheel inlet roller way, a lower machine frame, lower guide posts, lower air cylinders, a supporting plate, guide sleeves, a lifting table, guide rails, a clamping cylinder, a left sliding plate, a right sliding plate, a rack and pinion, servomotors, a lifting roller way, clamping wheels, a first servomotor, and a overturning platform.

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 high efficiency grinding machine for grinding the pin on a crankshaft has a machining space with a grinding wheel mounted on the lower end of an arm to form a pendulum assembly. A headstock supports the crankshaft in the machining space. A pivot drive rocks the pendulum assembly back and forth equal distances about the equilibrium position causing the grinding wheel to follow the non-circular path of a pin as the crankshaft as it is rotated about its elongated axis.

One object is to improve the uniformity of polishing of a substrate.

The present application discloses, as one embodiment, a substrate polishing device for a quadrilateral-shaped substrate, the device including: a surface plate; a substrate support mechanism that is attached to the surface plate and that supports the substrate; a polishing head mechanism for attaching a polishing pad, the polishing head mechanism opposing the surface plate; and an orbital drive mechanism for orbitally driving the polishing head mechanism. The substrate support mechanism includes: a base plate; a plate flow passage provided to the base plate; and a plurality of substrate support chambers that are connected to the plate flow passage, wherein each substrate support chamber independently applies a vertical direction force to the substrate, and the vertical direction force applied to the substrate corresponds to an internal pressure of the substrate support chamber.

A grinding device of a travel path, on which traveling wheels of a rail-type vehicle roll, includes a grinder which grinds a surface layer of a travel path, a frame on which the grinder is provided, and a device traveling wheel mounted on the frame. The device traveling wheel rolls along the travel path on the top surface of the standard rail extending in the extending direction of the travel path.

Described is an apparatus for robot-aided grinding, comprising the following: a manipulator, a linear actuator, and a grinding machine which includes a rotating grinding tool and is connected to the manipulator via the linear actuator. The apparatus further comprises a protective cover that partially surrounds the rotating grinding tool, the rotating grinding tool protruding from the protective cover at least on a first side. An adjusting mechanism is provided which connects the protective cover to the grinding machine and is designed to adjust the position of the protective cover in relation to the grinding machine.

Methods are disclosed for performing operations such as cleaning, inspection or data acquisition on an external surface of a hollow cylindrical tubular. Preferred embodiments include providing a fluid dispenser and an abrasion assembly on a buggy that travels up and down the length of the tubular as the tubular rotates. The fluid dispenser includes nozzles that dispense cleaning fluids onto the tubular's external surface. The abrasion assembly includes a swivel brush and a brush train providing different styles of abrasion cleaning of the tubular's external surface. Preferred embodiments include robotically monitoring abrader contact against the external surface of the tubular, and, in response, dynamically adjusting the distance between the external surface of the tubular and the abrasion assembly.
