Automatic pallet change
Automatic pallet change is based on automatic change of production pallets between pallet stations which are equipped with pallet changing mechanism, and a pallet clamping base on the machine saddle. Pallet is arrested on the clamping base by means of two centering pins and locked by hydraulic mechanism. When two pallet system is used, pallets are changed directly between stations and the pallet base, In case 3 or 4 pallet system is used, pallets are changed by the help of rotary manipulator placed between stations and the pallet base.
