Abstract
A controlled lathe having a rotatable main spindle with a hollow interior and a plurality of radially adjustable guide bodies for guiding a rod having a portion located within the hollow interior of the main spindle. Each guide body rests on a support body and is adjustable with respect to the support body by an axially movable inner tube located within the hollow interior of the main spindle. Axial movement of the inner tube to adjust the guide bodies is effected by an adjusting member which is mounted on the end of the inner tube and which is rotatable with the main spindle during normal lathe operation. The adjusting member is threadedly connected to a member which is attached to the main spindle, and a holding device secures the adjusting member against rotation when the guide bodies are to be adjusted which causes axial movement of the adjusting member and the inner tube due to the threaded connection. The axial position of the inner tube and the radial position of the guide bodies is varied by controlled rotation of the main spindle while the adjusting member is secured against rotation.
