Technical Examples
  1. The present invention discloses a workshop unit for use as a grinding center that includes a support frame having a drive motor and a multi-station tool mounted thereto. Particularly, the grinding center may be used for operations including but not limited to grinding, buffing, polishing, sanding, and cleaning. The multi-station tool includes a plurality of rotary tools, a power transfer system, and a rotary tool selecting system. The power transfer system operates through a plurality of pulleys each in communication with at least one rotary tool and the drive motor through a plurality of transmission links. The rotary tool selecting system, which includes one or more control shafts and a clutch system, allows each tool to be selectively and independently operated. The present invention provides a cost and space saving apparatus in which several tools share expensive components and are arranged within one unit to provide more functionality in less space relative to the same tools purchased and operated individually.
