摘要： A cam milling machine having a headstock (2) and a tailstock (3), which are fixed on a bed (1) and are horizontally spaced from each other for carrying at a time two camshafts (W) to be rotatable respectively on their axes which extend horizontally in parallel relation with each other. Atool support carrier (4) is guided on the top of the headstock (2) and is movable by an index feed device in a horizontal direction parallel to the axis of each camshaft. Two tool supports each carrying a milling cutter (20) are carried on the tool support carrier (4) to be vertically movable by respective tool feed devices each for moving the milling cutter (20) associated thereto toward and away from one of the camshafts (W). The tool support carrier (4) is moved by an index feed device in the axial direction of the camshafts (W), so that each milling cutter (20) is selectively brought into alignment with one of cams on each camshaft (W).

摘要： A fillet rolling machine having a frame, on which a work spindle with a chuck is carried for rotation about a horizontal axis. A tailstock is mounted on the frame for supporting one end of a crankshaft to be processed while the same is grasped and rotated by the chuck. A head support is movable on the top of the frame in a direction parallel to the axis of the work spindle and carries first to third support shafts in parallel relation with the axis of the work spindle. The first and second support shafts, disposed in parallel with each other, respectively carry first and second rolling heads which respectively effect rolling treatments on fillets formed at one of journals and one of crankpins adjacent thereto of the crankshaft. The third support shafts, disposed co-axially with the first support shaft, carries a third rolling head which effects a rolling treatment on a fillet formed at a front journal of the crankshaft. Each journal and crankpin gripped by the front ends of the associated rolling heads are given rolling treatments during the rotation of the work spindle. A servomotor controllable in accordance with numerical control data is drivingly connected to the head support, so that first and second rolling heads can be brought into respective alignments with any pair of a journal and a crankpin of the crankshaft.
