Machine tool with feed system

Image Number 4 for United States Patent #6647846.

A machine tool having a C-shaped frame has a workpiece processing station adjacent the open end of the throat, and an elongated guide rail extends in a first axis perpendicularly to the throat. A carrier extends along the guide rail, and a multiplicity of guide units are spaced along and movable on the carrier in the first axis. Workpiece clamping units are carried by the guide units, and drive means moves the guide units on the carrier. The guide rail is movable in the throat along a second axis perpendicular to the first axis, and a second carrier supported on the frame extends in a second axis parallel to the throat. A multiplicity of guide elements is spaced along and movable on the second carrier and supports the guide rail for movement in the second axis of the second guide rail.
