MACHINE AUTOMATIQUE A FILETER PAR PEIGNES

摘要

An automatic thread cutting machine having a workpiece spindle, a tool support disk which can be rotatably indexed about a geometric axis intersecting at right angles the axis of rotation of the workpiece spindle. At least one thread cutting device is secured to the tool support disk. The thread cutting device guides a thread cutting tool holder at a housing for carrying out lengthwise movements in radial direction to the tool support disk and transverse movements in the direction of the aforementioned geometric axis. A shaft mounted at the housing supports a cam element for controlling the lengthwise movements and a cam element for controlling the transverse movements. A drive connection is provided between this shaft of the thread cutting device and the workpiece spindle, and a motor driven mechanism is provided for moving the tool support disk in the direction of its geometric axis.
