A machine featuring a treatment tool that grinds a surface to a desired profile, imparts a desired roughness to that surface, and removes contamination from the surface, the machine configured to control multiple independent input variables simultaneously, the controllable variables selected from the group consisting of (i) velocity, (ii) rotation, and (iii) dither of the treatment tool, and (iv) pressure of the treatment tool against the surface. The machine can move the treatment tool with six degrees of freedom.

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.

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.

Provided are a combined machining apparatus and a combined machining method capable of performing machining with higher accuracy and at a high speed. The apparatus has a stage unit; a mechanical machining unit including a mechanical machining head having a tool configured to machine a workpiece; a laser machining unit including a laser machining head configured to emit laser for machining the workpiece; a moving unit; and a control unit that controls the operation of each unit, in which the laser machining head has a laser turning unit that turns laser relative to the workpiece, and a condensing optical system that focuses the laser turned by the laser turning unit, and a position at which the workpiece is irradiated with the laser is rotated by the laser turning unit.

A power tool including a housing with an electric motor in the housing. The motor has a stator and an armature, the stator having field coils and the armature having an armature shaft on which a commutator is affixed. A pair of brush boxes are located in the housing on opposite sides of the commutator. An orbit mechanism coupled to the armature shaft and a platen is coupled to the orbit mechanism. The field coils comprise a first field coil facing a front of the sander and a second field coil facing a rear of the sander and the brush boxes are rotationally offset from the field coils with respect to a vertical axis of the sander.

A machine featuring a treatment tool that grinds a surface to a desired profile, imparts a desired roughness to that surface, and removes contamination from the surface, the machine configured to control multiple independent input variables simultaneously, the controllable variables selected from the group consisting of (i) velocity, (ii) rotation, and (iii) dither of the treatment tool, and (iv) pressure of the treatment tool against the surface. The machine can move the treatment tool with six degrees of freedom.
