Abstract
A grinder equipped with a curved motion mechanism to process a working piece to form a double-envelope structure includes a grinding wheel, a driving shaft, a track bracket and a holder. The grinding wheel includes a grinding edge which has a grinding zone in contact with the working piece. The driving shaft drives the grinding wheel spinning. The track bracket holds the driving shaft and is movable in a curved motion against the holder. The driving shaft is coupled with the track bracket via a middle section and driven by the curved motion to tilt against the holder and oscillate about the grinding zone of the grinding wheel as an oscillation center. Thus the invention can process the working piece at varying angles to form a worm with the double-envelope structure and improve process precision.
