Abstract: PURPOSE:To obtain high accuracy products and to achieve the reduction in cost by applying an electric discharge machining on the contact surfaces of pieces, which are to be in contact with a pulley, in a set condition being linked together in an endless orbital belt prior to the finishing of pieces. CONSTITUTION:Pieces 2 are formed from a sheet metal by a press, or the like, and after heat-treated, they are assembled in an endless orbital belt prior to the finishing so as to be constituted in the form of a belt. Then, the belt 1 is set on the lower side electrode 9 in a processing liquid tank of an electric discharge machine, and by lowering the upper side electrode 10 electric discharge machining is carried out for the contact surfaces 2b of the pieces. After the 2b surfaces have been machined, the upper side electrode 10 is raised, and the belt 1 is reversed and then the contact surfaces 2a are machined. As a result, on the contact surfaces 2a, 2b matte finish is given, and this acts as an oil reservoir and suppresses the generation of friction heat at the time when the belt 1 is being driven, thus a smooth belt transmission can be obtained.
