Blade mechanical hand main task is plete simulation manpower blade moves to the main axis of machine tools and equipment and provide power for scutlery,movements. Mechanical hand should have sufficient torque, the torque must be constant (scale). At the same time, they should also have the structure to mechanical hand tight, a small space characteristics to meet different types of machine tools condition. To achieve digital processing center axis vertical placement, tool carrier axis level, the knives use mechanical hand vertical axis achieve automatic blade moves. The manipulator arm can turn processing center functions have been enhanced so that it can better meet production processing needs, and further enhance the degree of automation of processing and improve production efficiency. The second part of paper is the discussion overall of the design and the programme of translation. Analysis the programme and choose the best option, followed associated with the calculation accuracy and intensity. PC or PLC system using automatic blade control it through several signal lines and liaison with centre puter system established since diagnosis, adaptive function to achieve the fully automatic control system for blade management. Processing center with automatic changer devices, a place can do more work processing, put many related to decentralization processes together to form a working center for the multiprocessing system automatically processes, thereby greatly reducing the machine tools, spare parts handling time and the replacement of cutlery time, changed the production of a small, one plane, cut situation.
