Then, the power is transmitted to a swing arm to unload the first pallet from the table to a stand-by position and a second pallet, mounting thereon a workpiece to be machined, is loaded from the stand-by position to the table by the swing arm. The second pallet is the clamped on the table by the clamp member and the pallet exchange operation is complete.
