PCT No. PCT/EP83/00010 Sec. 371 Date Sep. 16, 1983 Sec. 102(e) Date Sep. 16, 1983 PCT Filed Jan. 18, 1983 PCT Pub. No. WO83/02411 PCT Pub. Date Jul. 21, 1983.A crankshaft turning machine operating on the dual cam principle, in which the gyro cutterhead (51) is carried in an internal eccentric cam (11) and the latter in an external eccentric cam (15) rotatable in a housing, both cams being adjustable as to their mutual position. For purposes of avoiding the creation of flattened portions at the crankpins to be machined at the transition from the plunge cut to the circular feed, the design is such that the transition from the plunge cut turning process to the circular feed turning process takes place without any feed stop phase. |
