In wooden door production,hardware hole and slot of wooden door leaf were usually processed by multiple procedures,which caused a poor processing accuracy and low productivity.Based on structural characteristics and principles of computerized machining,the authors developed a kind of numerically controlled door lock hole and slot processing machine which could provide loading and unloading door leaf material automatically,automatic bar code identification,automatic door leaf size measurement with compensation and door leaf servo clamping.Using the computerized machine,the processing of hardware hole and slot on both sides of wooden doors leaf were able to finish in a single position clamping.
