Abrasive material, characterised in that the abrasive material (1) includes a double layer of fabric (2) with connection (3) cut in the middle to form hairs (4) or fibres (4) on the first side (5) of the abrasive material (1), where the hairs (4) are post-treated so that the shape of the hairs (4) is permanently changed, and where the hairs (4) are equipped with abrasive particles (8).

Polishing media in the form of bristles made from a porous polymer-based material, apparatus and systems including the media, and methods of forming and using the media, apparatus, and systems are disclosed. A method of manufacturing bristles for use in polishing a workpiece which includes a non-planar surface includes the steps of combining a liquid polymer material and a foaming agent to form a foamed polymeric material, and separating the foamed polymeric material into a plurality of bristles. The foaming agent is configured to impart a porosity to the polymeric material, where the porosity is characterized by a density in the range of 0.3 to 1.2 g/cm.sup.3.

A grinding or polishing brush is provided and includes a main body which is rotatable about a central axis and is provided with bristles which extend with their center axes substantially in the direction of the central axis. In order, with such brushes, to permit pin point working, it is proposed that the center axes of the bristles have an inclination in the circumferential direction and/or inward in the radial direction. The effect which can therefore be achieved with the bristles is that they are supported against one another. In order to improve this, the bristles can be provided in an axial portion with film elements connecting them. The film elements may be able to come apart depending on wear.

A wheel brush (1) includes a grinding element bundle holder (3) having an annular grinding element bundle-holding surface (12) that faces the outer circumferential side and a plurality of grinding element bundles (4) that are formed by gathering a plurality of wire-shaped grinding elements (5). The grinding element bundle-holding surface (12) has a plurality of holding holes (16) arrayed in a circumferential direction (R), the grinding element bundles (4) protrude to the outer circumferential side from the grinding element bundle-holding surface (12) while one end portions are inserted into the holding holes (16). First protrusions (18) protruding to the outer circumferential direction are provided on first opening edge portions (17a) adjacent to the holding holes 16 at a first direction (L1) side in the rotational center line direction orthogonal to the circumferential direction R (R) in opening edges of the holding holes (16) in the grinding element bundle-holding surface (12). The first protrusions (18) are continuous in the circumferential direction R (R) to configure an annular first flange portion (19).

A polishing tool unit (1) includes a brush-shaped grinding stone (4) and a tool holder (2). The tool holder (2) includes a shank (2a), a sleeve (6), a gear screw (30), and a nut (36). The nut (36) is screwed onto a bolt portion (34) of the gear screw (30). The brush-shaped grinding stone (4) is connected to the front side of the nut (36) and held by the tool holder (2). The gear screw (30) is rotatable relative to the shank (2a) and the sleeve (6) about the axis (L). While rotation of the nut (36) about the axis (L) is regulated, the gear screw (30) is rotated, whereby the nut (36) is moved and the protruding amount of linear grinding members (3) is adjusted.

An example system for monitoring contamination level of effluent of an offline brush conditioning system includes a first reservoir configured to collect a first effluent from a first portion of a brush in the offline brush conditioning system and a second reservoir configured to collect a second effluent from a second portion of the brush, where the second portion is different from the first portion, and the first and second effluents are from a fluid used to condition a brush configured to clean a surface of a semiconductor wafer. An effluent contamination monitor is configured to monitor a first contamination level of the first effluent and a second contamination level of the second effluent.

A polishing brush (4) includes a grinding element bundle (9) formed with a plurality of wire-shaped grinding elements (28) formed by impregnating and solidifying an assembly of inorganic filaments with resin, and a grinding element holder (7) having a holding hole (20) holding the base end portion of the grinding element bundle 9 on an outer peripheral side surface (7c) serving as a grinding element-holding surface. The grinding element bundle (9) has a front surface (9a) facing forward in a rotational direction (R1) and a back surface (9b) facing backward. The grinding element bundle (9) is held in the grinding element holder (7) such that the front surface (9a) and the back surface (9b) are inclined in the same direction relative to a virtual surface (30) that includes a center point (P) of a cross section (9d) of the grinding element bundle (9) cut across an outer peripheral side surface (7c) and the axis of center of rotation (L) of the grinding element holder (7) and extends in a radial direction. The wire-shaped grinding elements (28) included in the grinding element bundle (9) are easily displaced and can release excessive force applied thereto.

A honing brush is provided comprising a brush hub having a face wherein the face has at least one or a plurality of two or more outwardly projecting bristles having a length that is from about 15 millimeters to about 25 millimeters, a grit size of about or greater than 240 grit to about 800 grit, a diameter of from about 0.2 millimeter to about 0.8 millimeter, and wherein the plurality of bristles are arranged in either a non-tufted bristle arrangement or a tufted bristle arrangement, and wherein each of said bristles is made of a polymer material.

A modified honing brush is provided comprising one or more bristles and one or a plurality of reusable stackable plates having one or more holes or voids located in the plates, or one or more support guides, and wherein each of the bristles is independently fitted through one or more of the holes or voids of the plates or surrounded by one or more support guides.
