Disclosed is a process for making a grinding wheel for the squaring of ceramic, formed by a support body and an abrasive ring. The process does not involve costly workings on the body and on the ring and produces a light grinding wheel which, therefore, is more practical to be handled by the handling machine.

A bonded abrasive wheel is disclosed comprising a plurality of abrasive particles disposed in a binder, a first grinding surface, a second surface opposing the first grinding surface, and an outer circumference. The wheel comprises a rotational axis extending through a central hub and a circuit configured as a Radio Frequency Identification (RFID) unit coupled to the abrasive wheel. The circuit comprises an antenna configured to communicate with one or more external devices and comprising a first end and a second end, wherein antenna has a radius of curvature about an axis along at least a portion thereof such that the first end is disposed adjacent to but is spaced from the second end, and an integrated circuit (IC) operably coupled to the antenna and configured to store at least a first data.

A stand up sander assembly for sanding a floor with a weed trimmer includes a cup that is mountable to a drive output of a weed trimmer such that the cup is rotated by the weed trimmer when the weed trimmer is turned on. A coupler is removably coupled to the cup. The coupler lies on a plane that is oriented perpendicular to a rotational axis of the drive output. A sanding disk is removably attached to the coupler. In this way the sanding disk can be positioned against a surface to be sanded when the weed trimmer is manipulated. The sanding disk is comprised of an abrasive material thereby facilitating the sanding disk to sand the surface.

With a method for the production of a grinding tool, a tool base body is provided, which configures a three-dimensionally shaped adhesive sur-face by application of a bonding agent. The tool base body is positioned in a way that the adhesive surface is arranged in an electrostatic field, be-tween a first electrode and a second electrode. Into the electrostatic field, abrasive grains are introduced, which, due to the electrostatic field, move towards the adhesive surface and adhere to same. The grinding tool produced in this manner has a three-dimensionally shaped abrasive grain layer. The production of the grinding tool is simple, flexible and economical. The grinding tool has a randomly shaped abrasive grain layer and can be applied in a manifold manner with a high cutting performance and a long service life.
