A compoundless buff and method of making a compoundless buff using a coating solution formulated with abrasive particles dispersed or suspended using a surfactant or suspension agent and which also contains a self-crosslinking acrylic binder emulsion that binds abrasive particles to nonwoven cloth of a buffing article when the coating solution is applied thereto forming a relatively hard abrasive-containing coating that enables the buffing article to abrasively treat a surface without having to separately apply any buffing or polishing compound. A preferred coating solution formulation further contains a lubricant emulsion that produces a lubricant and abrasive-containing coating of the buff having lubricant interspersed with binder and abrasive particles thereby reducing friction during buffing or polishing. A preferred coating solution also contains at least one surfactant to disperse the abrasive, suspension agent to keep the abrasive suspended, and buffering agent to keep the pH of the solution so it remains flowable.

The present disclosure relates to abrasive buffing articles (“abrasive buffs”) and methods of making the same. The abrasive buffs include a substrate, such as a fabric, that has been impregnated with an abrasive polymeric composition that includes abrasive particles, such as primary abrasive particles and/or abrasive aggregates, such as spray dried abrasive aggregates. The abrasive buffs are flexible and capable of conforming to and effectively abrading, polishing, and buffing workpieces possessing a complex geometry.

A roughing grinding tool has a supporting body and at least one abrasive circle. The supporting body includes an abrasive grain for roughing grinding. The supporting body serves to support the at least one abrasive circle and itself for roughing grinding. The roughing grinding tool is easy to produce and robust and has a high removal capacity in conjunction with a long service life.

Embodiments described herein generally relate to a grinding disc is being rotatably drivable around an axis of rotation. The grinding disc has a front side as well as a rear side facing away from the front side. The grinding disc further includes a multi-layered circular grinding blank packet with a plurality of circular grinding blanks. The grinding blanks are flatly stacked over each other along the axis of rotation and in which each grinding blank includes a central through opening. The central through openings form together a recess of the circular grinding blank packet. Wherein the grinding disc has a backing plate, which is arranged in the recess, and the circular grinding blanks each are fixed individually to the backing plate.
