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.

A long rod polishing device includes a prismatic or columnar battery, a battery mounting portion, an electric motor, a pad, and a rod portion. The battery is mountable to the battery mounting portion. The electric motor is driven by an electric power from the battery. The pad has a polishing surface and moves by a driving force from the electric motor. The rod portion has an end portion to which the pad is coupled. The battery mounted to the battery mounting portion has a longest side. The longest side has a direction so as to form an angle with respect to a second imaginary straight line. The second imaginary straight line is perpendicular to both of a center axis of the rod portion and a first imaginary straight line. The first imaginary straight line is perpendicular to the center axis and parallel to the polishing surface of the pad.

An attachment for a mobile handling device is configured for processing walls or ceilings. The attachment comprises a mounting unit that is arranged to be supported at a mounting interface of the handling device, a processing head that is arranged to be equipped with at least one tool for material-removing processing or smoothing processing, and a compensation arrangement that is arranged between the mounting unit and the processing head and that defines a longitudinal axis. The mounting unit provides at least two pivot positions for the attachment that are offset from one another. The processing head is movable relative to the mounting unit in a longitudinal direction along the longitudinal axis. The compensation arrangement is configured to provide a defined contact pressure force for the processing head in a defined operating range along the longitudinal axis towards the surface to be processed.

Disclosed herein are grinding machines for forming a trench. Embodiments relate to a grinding machine with a grind head and a vehicle mount. The grind head includes a housing body and a grinding drum. The vehicle mount is configured to attach the housing body to a vehicle. One embodiment of the disclosure relates to a trunnion attachment configured to attach the housing body to a vehicle such that the housing body is configured to roll about a roll axis oriented in a travel direction relative to the vehicle mount. The roll axis is proximate an initial contact point of the blade set. In another embodiment, a caster attachment is configured to attach the housing body to a vehicle such that the housing body is configured to yaw about a yaw axis oriented in an upward direction relative to the vehicle mount.

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.

A method and apparatus is provided for treating a floor surface with zero-tolerance edging. The apparatus includes a frame and wheels mounted to the frame so the frame can travel over the floor surface. The apparatus also includes a motor mounted to the frame and a head assembly including a bottom plate. The bottom plate is operatively coupled to the motor so that the bottom plate is configured to rotate about a first axis. The bottom plate is positioned such that a tooling plate mounted to the bottom plate is configured to treat the floor surface including an edge of the floor surface intersecting a wall surface.

A grinding machine for finishing turned surfaces of a rotor disc for a gas turbine engine, including a retaining mechanism for retaining the rotor disc and rotatable about a rotational axis corresponding to a central axis of the rotor disc, a spindle engaged to a grinding wheel and rotatable about a rotational axis corresponding to a central axis of the grinding wheel, the grinding wheel having an outer super abrasive surface, a translating mechanism engaged to at least one of the retaining mechanism and the spindle and actuable to provide a relative translational motion between the retaining mechanism and the spindle along three perpendicular axes, and a pivoting mechanism engaged to one of the retaining mechanism and the spindle and actuable to provide a pivoting motion of the rotational axis of one of the retaining mechanism and the spindle around a pivot axis perpendicular thereto.

A portable rasping platform for rasping a top surface of a wall panel includes a plurality of adjustable leveling supports, a pair of support rails, and a drum rasp assembly. The drum rasp assembly includes a drum rasp, a motor coupled to the drum rasp and configured to rotate the drum rasp at a suitable speed, and a truss frame supporting the drum rasp and configured to roll along the pair of support rails. The pair of support rails are configured to be positioned on the plurality of adjustable leveling supports arranged in parallel a certain space apart, and the plurality of adjustable leveling supports are configured to support the wall panel. The drum rasp is configured to pass over and treat the top surface of the wall panel as the drum rasp assembly is displaced along the pair of support rails.

An apparatus for surface finishing includes a robot and an end effector. The end effector includes a compliance wrist having an axis of movement and coupled to the robot and a grinder tool coupled to the compliance wrist. The robot is configured to controllably position the end effector in three-dimensional space. The compliance wrist is configured to bias the grinder tool to a biased position relative to the robot and enable the grinder tool to move relative to the robot in response to an external force acting upon the grinder tool.
