Abstract: 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.

Abstract: There is described a grinding wheel (1), particularly for grinding operations carried out on sheets of glass (2), ceramic material or similar materials, comprising a disc-shaped support with abrasive material arranged on the circumferential profile of the support, and an opposing central hole (3) for attachment to a drive shaft (4) of the grinding wheel. The disc-shaped support comprises a pair of opposed disc-shaped grinding wheel bodies (5, 6) coupled in a facing position so as to define together the abrasive grinding surface (5c, 6c) along the circumferential profile, and each of the disc-shaped bodies (5, 6) has a predetermined resilience such that the disc-shaped bodies (5, 6) can be flexed away from each other in the zone of contact with the component being ground, for the purpose of consequently applying pressure to the component in the grinding operation.

Abstract: A surface fine machining tool has a working medium carrier with a bottom side and a top side. Grooves extend from the top side to the bottom side completely through the working medium carrier and have a narrowed portion at the bottom side but do not narrow upwardly toward the top side. The working medium carrier is an injection-molded plastic part. Lamellas with a holding rim and a lamella body are inserted with the holding rim in the grooves. The lamella body extends downward away from the holding rim, passes through the narrowed portion, and extends away from the bottom side. The lamellas are uniformly distributed about the bottom side. The grooves have an open end at a carrier rim of the working medium carrier. The open end has a cross-section matching the groove cross-section. A cover is connected to the top side and covers grooves and holding rims.

Abstract: This invention relates to a grinding tool, and more particularly, it relates to a diamond grinding disc adapted for grinding. The diamond grinding disc is connected to a grinder via a post to be available for grinding a workpiece. The diamond grinding disc comprises a grinding layer, a transition laver, a back layer, wherein the post is a screw structure upwardly extended from the back layer, wherein the back layer is connected to the transition layer to form integration. The design, setting the back layer and the transition layer as an integrated part and applying soft material on the back layer, solves the problem that the back layer and the transition layer are easily disconnected from each other and prolongs the service life of the grinding disc.
