ABSTRACT:
The invention relates to a program-controlled milling and drilling machine comprising a machine column, a machining unit comprising a milling head and being movable along at least one coordinate axis at the front of the machine column, a machine bed disposed in front of the machine column, a work carrier movable on the machine bed along another coordinate axis, and a pallet exchanger arranged at the free end portion of the machine bed, having two spaced apart pallet holders and a rotating and lifting mechanism on a joint load-bearing structure. According to the invention, the load-bearing structure of the pallet exchanger is laterally arranged next to the machine bed and has a dimensionally stable and sturdy transverse arm extending across the machine bed and supporting the rotating mechanism, the lifting mechanism in the load-bearing structure laterally arranged next to the machine bed being arranged in a manner so as to protect against dirt by a splashboard.
