Abstract:
PURPOSE:To grind cylindrical surface efficiently and uniformly by placing cylindrical or column-shaped work to be ground level in a horizontal type cylindrical grinding trough, and by agitating a dry medium both by orbiting and rotation round own axis. CONSTITUTION:A plurality of works to be ground 36 are fixed to jigs 20, 27, and a dry type medium 37 is put in a grinding trough 8. Together with main shaft 4, a support 12, coupling shaft 22, support 21 and follower shaft 6 are rotated by a motor 28 so as to the shafts 17, 26 which are rotating round own axies. This rotation allows a planet gear 19 meshing with a fixed gear 16 to roll and spin round its own axis so as to permit each work 36 to orbit and spin round own axis. The grinding trough 8 is rotated by another motor 32. Rotation of these members provides effective agitation of the medium 37, which flows well to polish the outside cylindrical surface of the work 36. Thereby the cylindrical surface of a comparatively long cylindrical or column-shaped work can be automatically polished quickly, efficiently and uniformly throghout the surface concerned.
