A grinding/milling machine for levelling of horizontal surfaces, having a mobile drive unit, including a vertically pivotable boom suspended from the mobile unit, a rigid girder pivotally fastened at the end of the boom and two motorized machining and/or milling machines, each being arranged at a respective opposite end of the rigid girder.

A surfacing apparatus supported adjacent a substantially vertical surface of a structure for applying an even and uniform texture to the surface of the structure using a selectively adjustable force exerted on a texturing means to engage the surface of the structure. The surfacing apparatus is suited for horizontal and vertical movement in controlled prescribed paths under controlled and prescribed pressure from the adjustable tensioning means.

The invention concerns a processing apparatus for processing an upper segment edge of a pylon segment of a concrete pylon for preparing the pylon segment for placement thereon of at least one further pylon segment. According to the invention it is proposed that the processing apparatus includes a processing means for processing the segment edge, and a carrier apparatus to be fixed in the region of the segment edge for displaceably carrying and guiding the processing means along the segment edge.

An edge grinding tool is disclosed for dressing the edge of a workpiece using a hand grinder. The tool includes an elongated fence plate with a centrally aligned raised fence that has symmetrical, downward-diverging side surfaces. A grinder holder, attachable to various grinder heads via an optional adapter plate, features a guide plate with wheels that engage the fence's diverging surfaces, enabling smooth, controlled longitudinal movement. A second embodiment features a dual-guide plate system with spring-loaded engagement and a lever mechanism, enabling secure, hands-free operation by locking the grinder holder onto the fence. The tool supports different grinder configurations and includes optional wear and friction strips for added stability. The symmetrical fence design enables the fence plate to be rotated and reused on opposing workpiece edges, resulting in seamless joints. This invention improves precision, repeatability, and ease of use in edge dressing applications, especially for stone or concrete countertops.

The present application includes methods, apparatuses, and systems for cleaning an aluminum wheel. In particular instances, a method of treating an exterior surface of an aluminum vehicle wheel comprising: blasting the exterior surface a first occurrence for a first duration at a first velocity using blasting media; blasting the exterior surface a second occurrence for a second duration at a second velocity using blasting media after blasting the exterior surface for a first duration, the second velocity being substantially lower than the first velocity; and, arranging the vehicle wheel in contact with vibratory finishing media and vibrating the vehicle wheel with the vibratory finishing media for a duration after blasting the exterior surface in each of the first and second occurrences.
