A driver interface for a grinding head includes a center plate having top and bottom surfaces, an outer edge, a mounting channel in the top surface, and mounting pads on the bottom surface, each pad having a raised edge. An upper clamping plate is inserted within the mounting channel. A lower clamping plate defines disk locating apertures and fastens to the bottom surface of the center plate so that each of the disk locating apertures surround the raised edge of a mounting pad. The upper and lower clamping plates are removably fastened to the center plate. A disk attacher having an anchoring portion and a disk receiving portion bends around the outer edge of the center plate so that the upper clamping plate when fastened to the center plate clamps the anchoring portion between the upper clamping plate and the mounting channel, and so that the lower clamping plate when fastened to the center plate clamps the disk receiving portion to a mounting pad and within one of the disk locating apertures.

A disc tool for a processing machine for grinding and/or polishing a workpiece (W); wherein the disc tool (10A, 10B, 10B) has a carrier (20) for attachment to an output (85) of the processing machine (80); wherein a cushion element (40A, 40B, 40C) made of elastic material and a retaining wall element (41A, 41B, 41C, 41D) for retaining the cushion element (40A, 40B, 40C, 61) are arranged on the carrier (20); wherein the retaining wall element (41A, 41B, 41C, 41D) is held on the carrier (20) by means of retaining bolts (35); wherein retaining bolt passage openings (48) of the retaining wall element (41A, 41B, 41C, 41D) extending through retaining mounts (28), of the carrier (20) are accommodated along bolt sections (36) of the retaining bolts (35) extending along the bolt longitudinal axes (BL), and the retaining wall element (41A, 41B, 41C, 41D) is held between bolt heads (37) of the retaining bolts (35) and the carrier (20); and wherein an adhesive layer (50) is arranged on a side of the retaining wall element (41A, 41B, 41C, 41D) opposite the carrier (20), on which adhesive layer a processing means (70) for grinding and/or polishing the workpiece (W) can be releasably attached to the disc tool (10A, 10B, 10B). The adhesive layer (50) has recesses (52) assigned to the bolt heads (37).

A floor cleaning and polishing device has a polishing pad for a surface which is rotationally engaged upon a pad driver operatively engaged to a frame. A first set of wheels on the frame allow for tilted movement. A second set of wheels are positionable to a deployed position to elevate the first set of wheels from the surface and position the polishing pad parallel to the surface. The device may have a light projector engageable for light disinfecting. The polishing pads are configured with a plurality of polishing fabric sections separated by recesses therebetween.

A walk-behind grinder/polisher receives removably attachable wet and dry debris collection modules. These modules are substantially rigidly attached to the frame of the grinder/polisher and suspended above a floor surface so as to travel with the grinder/polisher when coupled thereto. Each debris collection module removably attaches to a vacuum producer mounted on the frame of the grinder/polisher. An engine drives a first hydrostatic pump in fluid communication with a first hydraulic motor driving the grinding/polishing head in reversible fashion. The engine further drives a second hydrostatic pump in fluid communication with a second hydraulic motor driving the vacuum producer. The dust collection module has an inlet removably attachable to the dust collection port on the shroud, and an outlet coupled to a dust collection canister. The slurry collection module has an inlet removably attachable to a squeegee, and an outlet coupled to a slurry containment vessel.

A grinding head assembly for a floor processing machine includes a plate that has a first side that has a tool attachment surface and a second side opposite the first side. A plurality of lippage adapters are attached to the second side of the plate. The plurality of lippage adapters each include a base portion that have a tool contact surface partially surrounded at a perimeter wall and are removably attached to the second side of the plate with at least one fastener. Each of the plurality of lippage adapters includes at least one magnet fixed to the base portion.

Multiple floor treatment operations, such as burnishing, polishing and scrubbing, may be performed using a single floor treatment machine having a motor, the speed of which is governed by a controller that responses to sensor signals indicative of the type of floor treatments pad or pads operatively coupled to the motor.

The present disclosure relates to a grinding head for a floor grinding machine for grinding floor surfaces of stone or stone-like material. Such a grinding head comprises a lower casing member, comprising a lower support and an upwardly extending edge portion, and an upper casing member, comprising an upper cover and a downwardly extending edge portion, wherein the upper casing member is joinable to the lower casing member by causing axially distal portions of the edge portions to bear on each other.

Systems and methods for treating concrete, which includes the steps of wetting a surface of concrete with colloidal silica, allowing time for the colloidal silica to penetrate the concrete surface, and cutting the surface of the concrete with a bladed or segmented tool wherein the longitudinal blade or edge portion is positioned approximately at an angle between 30 degrees and 90 degrees relative to the surface of the concrete.
