Abstract
A machine tool for continuously working the surface and the back of a workpiece, comprising a chuck base which is supported so that it is able to approach to or move away from the workpiece, on which a tool spindle for holding a cutting tool and a chuck for holding the workpiece are mounted, and which is able to rotate about the rotation axis perpendicular to the tool-spindle moving direction and a reversing mechanism which is arranged at the front in the direction perpendicular to the spindle moving direction and the chuck-base rotation axis, receives a workpiece, reverses the workpiece, returns the reversed workpiece to the chuck, and changes the portions of the workpiece facing a cutting tool.
Claims5
A machine tool for continuously working the front surface and the rear surface of a workpiece, comprising:
- a tool spindle which is supported so that it is able to approach to and move away from a workpiece and holds a cutting tool;
- a chuck base on which first and second chucks for holding a workpiece are mounted concentrically and back to back and which is rotatable about a rotation axis perpendicular to the tool-spindle moving direction;
- and
- a reversing mechanism which receives a workpiece held by the first chuck, reverses the workpiece, returns the reversed workpiece to the second chuck having a shape fitted to the shape of a worked portion of the workpiece, and changes the portions of the workpiece facing the cutting tool.
