A polishing tool with a carrier comprising a polishing surface on which a polishing paste is applied at least in some areas, wherein the polishing surface consists of a nonwoven fabric, the polishing paste is in a solid state at room temperature and is applied on the polishing surface to be covered in an amount of 0.08 g/cm.sup.2 to 0.30 g/cm.sup.2.

The present disclosure provides abrasive articles that include an abrasive layer having a contact surface, a first layer coupled to the abrasive layer, and a second layer coupled to the first layer. The first layer is configured to provide contact pressure to the abrasive layer, such as through a higher hardness than the second layer. The second layer is configured to provide conformability to the abrasive layer, such as through a higher compressibility than the first layer. The resulting abrasive articles may exert a consistent contact pressure against a substrate with increased conformability around the substrate, reduced hysteresis, improved removal rate consistency, and/or improved lifetime over abrasive articles that do not use the multiple layer construction described above.

A polishing device includes a substrate holder, a dispenser configured to dispense an abrasive to a surface of a substrate held by the substrate holder, a polisher including an elastic body configured to polish the surface of the substrate as the elastic body is rotated with respect to the surface of the substrate. An area of contact between the elastic body and the surface of the substrate during polishing is smaller than a surface area of a region of the substrate that is to be polished by the elastic body. The elastic body is moved, while the elastic body is rotated, with a downward velocity component prior to contacting the surface of the substrate and with an upward velocity component after the elastic body comes into contact with the surface of the substrate.

A buffing and polishing member has an uncompressed monolithic body of foam material having slits from an outside surface toward and less than a distance to a rotational axis of the body. The slits, on circumferential spaced planes, extend generally radially from the outside surface toward and less than a distance to the rotational axis to define a plurality of foam fingers and an unslit center portion. A fastening mechanism holds the center portion of the slit foam body in a compressed state along the rotational axis such that the uncompressed outer ends of the foam finger define a spherocylinder.

The present disclosure relates to a tool for sanding and buffing an irregularly shaped surface that includes a head having a rounded surface, a first abrasive material adapted for sanding or buffing, the first abrasive material attached to the rounded surface via an adhesive substance or other attaching means and at least partially covering the rounded surface, and a handle attached to the head. The tool may further include a second abrasive material attached to the rounded surface via the adhesive substance or other attaching means that at least partially covers a portion of the rounded surface not covered by the first abrasive material. If the first and second abrasive materials have varying properties such as their coarseness, the user may find each material to be especially efficient for use in separate sanding, buffing, or polishing processes.

An object of the present invention is to provide a porous material for polishing in which, during a polishing operation, it is possible to keep a proportion between abrasive grains in contact with an object to be polished and a resin portion in contact with the object to be polished within a certain range, even if an unskilled person attaches a polishing tool to an automated device and uses it, there is no need for complicated adjustment to stabilize the device, whereby it is possible to obtain precise surface accuracy. The above object is achieved by a porous material for polishing including an elastic foam having anisotropy, a polymer, and abrasive grains.

The invention relates to a brush grinding head (1) for a grinding machine (2), comprising an essentially roller-shaped carrier (3) and grinding lamellae (4), wherein the grinding lamellae (4) are arranged peripherally on the carrier (3) and are composed at least of, in particular bundled brushes (5) and an essentially strip-shaped grinding element (6) which is arranged adjacent thereto. The grinding element (6) comprises at least one abrasive layer (7) and an abrasive-free layer (8) which can be compressed while retaining its shape and is designed in such a way that a grinding fluid (27), in particular water, can be stored in it.
