... stoned and polished before a production run of 4000 forks. Workpiece surface finish improved to an average of 0.1 μm (5 μin.), as shown in Fig. 8 (lower sketch). To maintain this finish, hand polishing of the dies after each 1000 piece run was required. Coining was done in a 540 kg (1200 lb) air-lift...
