ABSTRACT:
Apparatus for facing and internal turning includes a rotatable shaft and a turning head fixed for rotation with the shaft. A tool carriage for carrying a cutting tool is displaceable on the turning head transversely to the axis of rotation thereof. The transverse displacement of the carriage is effected by way of two planetary gear units lying in planes at right angles to the axis of rotation of the shaft. The sun gear of the first unit is fixed for rotation with the shaft, whilst the sun gear of the second unit, which acts as a driving gear for the tool carriage, is rotatable relative to the shaft. A further ring gear is disposed coaxially with said gear units and engages a gear connected for rotation with the planet gear of the second unit. Fastening means selectively lock said further ring gear against rotation whereby the sun gear of the second unit is rotated relative to the shaft and effects transverse displacement of the tool carriage.
