ABSTRACT:
A machine bed carries outer platens and a center platen mounted, for relative movement, on the bearing faces of guides, to effect the feed. The working face of the center platen, whereon a device for clamping the workpieces is mounted, is arranged in a vertical plane. The outer platens extend vertically and carry spindle heads mounted thereon. The bearing faces of the guides are disposed above the center of gravity of each one of the platens mounted thereon for a convenient loading of workpieces and for the removal of cutting fluid and chips by gravity.
