Abstract
The abrasive system of the present invention is capable of automatically and efficiently feeding and discharging work pieces. In the abrasive system, an upper abrasive plate and a lower abrasive plate pinch the work pieces, which are provided in through-holes of a carrier and abrade both faces of each work piece. A carrier driving mechanism moves the carrier, along a circular orbit, without spinning, together with the work pieces. Stopping means stops the movement of the carrier at a predetermined position. The feeding-and-discharging means includes: an arm robot having a work holding unit, which is provided to a front end and capable of holding and releasing the work piece; and an image processing unit for recognizing shapes and positions of the through-holes of the carrier and the work pieces.
