1470414 Machine tool details; copy milling FRIEDRICH DECKEL AG 4 Oct 1974 [13 Nov 1973] 43261/74 Headings B3B and B3K A machine tool, in which a working tool 18 machines a workpiece in accordance with the movement of a tracer 16 passing over a pattern, comprises at least one tool turret 6 rotatable about a horizontal axis, a separately driveable spindle for rotatably driving the selected working tool 18 at a working position about an axis parallel to the turret axis, the turret being mounted for movement transversely of said axis, and a guide rotor 8 mounting the tracer 16 and being rotatable about a horizontal axis and movable transversely thereto with the same freedom for traversing movement as the or each turret 6, and whereby the drum 8 is coupled to the or each turret so that the movement of the tracer 16 over the pattern produces synchronous movement of the or each turret to machine the workpiece. The rotor 8 and turret 6 may be mounted as a common slide 4 for longitudinal and lateral movement relative to a bed 2, and coupled by a chain 24. Alternatively the rotor 8 may be mechanically independent of the turret 6 (Fig. 3, not shown) and connected thereto by electrical, hydraulic or pneumatic servo transmission means. The said transmission means may incorporate ratios to produce larger or smaller reproductions from the pattern. The rotor 8 may comprise a drum wheel or a radial arm. To align a different tool in the turret 6 with the drive spindle, the chain 24 is undone and the turret is rotated. The turret and guide rotor may be directly programmed by a computer. The programme may be read optically from a drawing. |
