    摘要: A shaping machine wherein either a work or a tool is a rod-like member extending along a straight center line while the other is a member having a hole capable of being fitted on the rod-like member and wherein the work is shaped while the member having the hole passes through the rod-like member from one end toward the other end of the rod-like member. The shaping machine comprises a feed mechanism for causing relative movement of the rod-like member and the member having the hole to each other along the center line of the rod-like member, a center line of the feed mechanism being coincident with the center line of the rod-like member.

    摘要: A hydraulic drive (10) for the adjustment, feed and return movements of a tool head of a machine tool comprises a hydraulic motor (11) and an after-running adjustment valve (12). The reference value of the position is set and the actual value indicated by means of a threaded spindle (39) and spindle nut (37) in the form of a hollow shaft. One of these two elements can be driven by an electric motor (41) in order to set the reference value of the position. The other of these two elements can be driven in order to indicate the value of the actual position. A rotational and angular position indicator system (68, 74, 75 and 69, 77) produces an output which is a direct measure of the total number of revolutions executed by the preset reference value shaft and of the azimuthal position of the preset reference value shaft within each revolution. An electronic position sensor system (71, 78 and 71', 78'; 71") produces an output which is a measure of the contouring error S. The actual position of the tool head or of the drive element of the hydraulic motor (16) is therefore phase-retarded in relation to its reference position by said contouring error.
