Method of grinding small components - involves using guide cam for tool working at constant loading

摘要

Uniform loading on the workpiece grinder is effected by a synchronised cam. The cam (9) and workpiece (13) are mounted on parallel horizontal shafts (7, 11) on a jack (3) mobilized, rail (2) guided table (1), the cam shaft being motorized and driving the workpiece shaft via tensioned (24) belt and pulleys (21, 22). The cam bears on a fixed abutment (10) and the workpiece on the grinder (17): the workpiece bearing shaft (11) also being capable of vertical displacement controlled by balls (16) running in vertical rails (15) and a cam (18) and idler wheel (19). The jack (3) presents the workpiece to the cam for a fixed time then retracts. Many refined developments are shown.
