A wheel grinding device consists of a lower lifting rotary system, spoke grinding units, a center hole grinding system and an upper lifting and clamping rotary system. The wheel grinding device not only can be used for grinding the center hole of a wheel of any size via brush units of the center hole grinding system, but also can be used for grinding the back of wheel spokes of different sizes and shapes via the actions of brush belts of the spoke grinding units.

A method for controlling polishing and grinding is provided, including: generating an initial polishing and grinding trajectory for robot movements based on a three-dimensional contour of a work piece; adjusting the initial polishing and grinding trajectory based on a first optimized adjustment value and generating an optimized polishing and grinding trajectory; and evaluating the polishing and grinding quality of the work piece and using the polishing and grinding quality to generate a second optimized adjustment value.

A device for the fine machining of a circumferential workpiece surface arranged eccentrically relative to an axis of a workpiece. The device comprises a pressure mechanism configured to press a fine-machining tool against the circumferential workpiece surface. The device also includes a drive unit configured to drive an active section of the pressure mechanism via a first drive and a second drive. The first drive drives the active section in a movement plane that runs crosswise to the workpiece axis along a first movement trajectory. The second drive drives the active section along a second movement trajectory that is at an angle to the first movement trajectory.

A pressure shoe (1) includes a press surface (2) for directly pressing finishing tape onto a radial circumferential surface (3) of a rotating workpiece section (4) during a finishing process. A plurality of expansion elements (5) is formed in the pressure shoe (1). Each of expansion elements (5) are expandable individually and independently of one another radially while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4), so that during the finishing process, the shape of the circumferential surface (3) of the workpiece section can be influenced in a targeted manner via different expansion of the expansion elements (5) distributed over the press surface (2).

This disclosure relates to a belt grinder includes frame and first grinding assembly. The first grinding assembly includes transmission roller set, grinding belt and adjusting assembly. The transmission roller set includes driving roller and driven roller. Both the driving roller and the driven roller are rotatably disposed on the frame. The grinding belt is installed over the driving roller and the driven roller. The adjusting assembly includes rotatable component and contact rollers. The rotatable component is rotatably disposed on the frame. Rotation axis of the rotatable component is parallel to rotation axis of the driving roller. The contact rollers are rotatably disposed on the rotatable component. Contact rollers are different in shape. The rotatable component is rotatable with respect to the frame so as to force one of the contact rollers to contact or to be separated from the grinding belt.

Wheel cleaning systems and methods are described for removing corrosion from a wheel rim. An enclosure comprises a plurality of walls that define a work area, and houses a turntable that can hold a wheel rim. The turntable is driven by a motor to rotate the wheel about an axis. The enclosure may have a transparent shield or window to allow a user to view the wheel during the cleaning process and be protected from sparks and other debris. The enclosure may be fully enclosed with gloved openings, or contain one or more open sections to allow the user to maneuver a tool (e.g., a grinder) in multiple positions within the enclosure, and clean the wheel rim. The system further comprises an exhaust unit that draws out small particles and airborne debris from within the enclosure, and produced during a cleaning process.
