Abstract
A machine having a plurality of workpiece spindles. The spindles are angularly disposed in an indexable support with the spindle axes making one and the same axis with the axis of the support and all being tangent to a common cylinder coaxial with the support axis. Means are provided for driving the spindles and chucks are mounted on one end of the spindles for carrying workpieces for cooperation with tools mounted in the frame in which the support is indexable.
Claims14
A multiple spindle workpiece turning automatic lathe machine having in combination a frame, said frame mounting tools disposed at plural work stations, a workpiece spindle support supported in the frame and having means for indexing between said work stations on a main axis, a plurality of workpiece spindles having workpiece holding means rotatably supported in said support, the axes of said spindles being the same radial distance from said main axis and each making the same actute angle of inclination to obtain free accessibility and greater freedom for turning rather than being close together in parallel with respect to said main axis when viewed in the direction of the common perpendicular to said main axis and the axis of the respective spindle, said spindle axes with said angle of inclination being tangent to the same cylinder coaxial with said main axis, the points of tangency of the axes of the work spindles to said cylinder being coplanar, and means to rotate said workpiece spindles.
