Opposed spindles lathe having tool rests movable in two different directions

An opposed spindles lathe, comprising:

• a frame;
• first and second spindle stocks disposed on said frame so as to face each other;
• first and second workpiece spindles rotatably supported by said first and second spindle stocks, respectively, each said workpiece spindle having a chuck for jointly holding therebetween, or independently and separately holding, a workpiece to be machined, and said workpiece spindles having a central axis;
• wherein said first and second spindle stocks are movably mounted on said frame so as to be movable only in the direction of the central axis of said first and second workpiece spindles;
• first and second tool rests disposed on said frame on the same side of the central axis corresponding to and adjacent to said first and second workpiece spindles, respectively, each said tool rest having means for moving said tool rest in at least a direction substantially perpendicular to the central axis of said first and second workpiece spindles and in a direction parallel to the central axis of said first and second workpiece spindles, and each said tool rest having a side thereof oriented substantially perpendicular to the central axis and facing the other said tool rest;
• and
• first and second rotatable tool holding turrets disposed on said first and second tool rests, respectively, so as to be freely rotatable on an axis parallel to the central axis of said first and second workpiece spindles, wherein said first rotatable tool holding turret is disposed on said side of said first tool rest facing said second tool rest and said second rotatable tool holding turret is disposed on said side of said second tool rest facing said first tool rest;
• said first rotatable tool holding turret having a periphersal portion with a plurality of tool installation portions thereon;
• and
• said second rotatable tool holding turret having a peripheral portion with a plurality of tool installation portions thereon;
• and
• wherein said means for moving said first tool rest can move said first tool rest in the direction parallel to the central axis of said first and second workpiece spindles in a first movement area, and said means for moving said second tool rest can move said second tool rest in the direction parallel to the central axis of said fist and second workpiece spindles in a second movement area having a common movement area overlapping said first movement area whereby tools on said first and second tool rests may operate upon a workpiece held separately in the chuck in either of said first and second spindle stocks.
