ABSTRACT:
Three machine tools are positioned in spaced apart relationship at the corners of a triangle. Each machine tool has a worktable which is rotatably mounted on a corresponding bed for rotation about a corresponding vertical axis. Each worktable has guide means for slidably receiving a pallet carrying one or more workpieces. At least three workpiece transfer units are each positioned adjacent to the worktable of a corresponding machine tool for interaction therewith. Each workpiece transfer unit has guide means for slidably receiving a pallet and has a hydraulically actuated slide which engages the pallet and moves it along the guide means to transfer the pallet from one machine tool to the adjacent machine tool. One or more workpieces are clamped on each pallet. The pallets are introduced into the loop at an operator's station. The pallets carrying the workpieces are transferred from one machine tool to the next around the loop, having work performed on the workpieces at each machine tool, and finally, being returned to the operator's station for unloading.
