In some embodiments a method can include providing a glass sheet to a coating chamber, and dispensing a coating on a major surface of the glass sheet. In some embodiments, a method can include providing a glass sheet to a fog chamber, providing fog to an enclosure of the fog chamber, and contacting a major surface of the glass sheet with the fog by passing the fog from the enclosure through a passage in the enclosure.

A rotary sanding system for retro fitting a Rotozip sanding disk to an air tool includes a first disk that may be removably coupled to an air tool thereby facilitating the air tool to rotate the first disk. The first disk has a plurality of openings extending therethrough and air may pass through the openings. A mating unit is coupled to the first disk. The mating unit engages the air tool thereby facilitating the first disk to be removably coupled to the air tool. A sanding disk is removably coupled to the first disk. The sanding disk may abrade a surface when the air tool rotates the first disk.

A rotatable grinding tool (1) comprising a disc-like body (2) defining an intended direction of rotation (D), in which the grinding tool (1) is rotatable about a central axis (A) of the disc-like body (2), and a front side (3) intended to face a surface to be grinded, and a back side (4) opposite to the front side. The grinding tool (1) further comprises, on the front side (3) of the body (2), a plurality of teeth (5) each extending radially along said front side (3), wherein said teeth (5) being arranged spaced apart from each other. Particularly, the teeth (5) are formed integral with the body (2).

The present invention is provided with a grinding block of dry grinding machine for grinding concrete and granite, the grinding block is assembled to a mill of the grinding machine, the grinding block comprises a fixing plate to fix the grinding block to the mill, wherein the fixing plate is welded with a grinding media, the grinding media comprises a plurality of grinding pieces, the grinding pieces are connected by a connecting strip or connecting strips arranged with space, the connecting strips with spaces divide with a plurality of air passages between two grinding pieces.

A diffusion plate includes a plate member facing an opening end of a supply pipe with a thickness direction thereof substantially parallel with a supply direction of a supply fluid. The plate member is rotatable around a rotation axis substantially parallel with the thickness direction and has a diffusion hole, penetrating in the thickness direction at a position other than a rotation center of the plate member. The diffusion hole has a wall surface defined at a rear side in a rotation direction and has a first wall surface end defined in a facing surface facing the supply pipe, at a rearmost in the rotation direction and a second wall surface end defined in a non-facing surface at a rearmost in the rotation direction. The wall surface is inclined with the first wall surface end being at a front side of the second wall surface end in the rotation direction.

Methods of making vitreous bond abrasive articles and their precursors using powder bed jetting are disclosed. Vitreous bond abrasive articles prepared by the method include abrasive articles having arcuate or tortuous cooling channels, unitary structured abrasive discs, abrasive segments, shaped abrasive particles, and abrasive wheels.

A grinding wheel includes an annular base having a free end portion and a plurality of segment grindstones fixed on the free end portion of the annular base in a state of being spaced from one another in a circumferential direction. The plurality of segment grindstones are divided into a plurality of grindstone groups each including a predetermined number of segment grindstones. Each of the segment grindstones included in each of the grindstone groups has a grinding surface formed into a rectangular shape having a long side and a short side. The segment grindstones of the grindstone group are sequentially fixed on the free end portion of the annular base from an outer circumferential side toward an inner circumferential side such that directions in which the long sides of the segment grindstones extend are changed from the circumferential direction to a diametric direction of the free end portion.

A grinding disc for a grinding device, with a fastening interface formed for rotationally fixed fastening to a driven member of the grinding device such that the grinding disc, limited by a peripheral disc rim surface, can be driven into a grinding movement. The grinding disc has a fastening surface on a working side, to which fastening surface a grinding means provided with an abrasion layer can be or is detachably fastened via fastening means. The grinding disc has dust extraction openings arranged on the fastening surface and air intake openings arranged on the disc rim surface, which are connected respectively to dust outlet openings arranged on the device side of the grinding disc via an extraction channel system running in the grinding disc, with the result that, during grinding, the resulting grinding dust can be removed by means of a dust extraction device coupled to the grinding device.

The present disclosure provides a carrier disk for holding at least one cutting, grinding or polishing element in a floor grinding machine. The carrier disk comprises a carrier body having a downwardly exposed face, at which the grinding element is arranged, a opening formed in the carrier body and a plurality of flanges extending axially from the carrier body and between the opening and a radially outer edge of the carrier body.
