The present disclosure presents a grinding apparatus for sharpening an edge tool. The grinding apparatus may comprise a grinding apparatus casing; a cylindrical grindstone and a support element. The cylindrical grindstone is removably attachable to the grinding apparatus casing. The support element is also removably attachable to the grinding apparatus casing for supporting the edge tool to be sharpened during the grinding operation. The support element includes an elongated member, which may be embodied as a cylindrical support bar. The cylindrical support bar may be configured to extend in a direction which is perpendicular to the rotation axis of the cylindrical grindstone, during operation, in such way that a grinding operation is enabled where the edge tool to be sharpened can be sharpened by means of the side surface facing outwardly from the grinding apparatus casing during the grinding operation.

A bench grinder safety and monitoring system for maintaining worker safety while using a bench grinder having a contactor wheel, a tool rest proximate the contactor wheel defining a tool rest gap and having a tongue guard proximate the contactor wheel defining a tongue guard gap. The system includes a first optical sensor situated within in the tool rest gap having an emitter portion coupled to the tool rest adjacent a first side of the contactor wheel and a receiver portion coupled to the tool rest adjacent a second side of the contactor wheel, the emitter portion configured to project a beam of light across the tool rest gap toward the receiver portion. A controller in data communication with the receiver portion of the first optical sensor, is configured to determine if the light beam is received by the receiver portion and, if so, to de-energize the motor.
