The sign type number controls the miller lord to spread to move the system design
　
　Abstract： this text introduces the sign type number to control some basic general situations of the miller, Chien says the tool machine lord to spread the principle and types of move the systems, analyzing various mechanism that spreads to move the project.The sign type number controls the miller lord to spread to move the system to include the principal axis electric motor, principal axis to spread to move the system and the principal axis module three partses to constitute.Detailed introduction of this text the sign type number controls the design process that the miller lord spreads to move the system, should the sign type number control the miller principal axis to become soon the box is to is carry on by wheel gear to spread to move of, the principal axis box spreads to move the system adoption wheel gear to spread to move, spreading to move the form adoption  concentration type to spread to move, the principal axis become soon many of the system adoption slip to move the wheel gear to become soon.The wheel gear spreads to move to have to spread to move the efficiency high, the structure tightly packed, work credibility, the life span is long, spreading to move than accurate etc. advantage.It introduced the sign type number to control the miller lord to spread to move various comparison, lord that spreads to move the project merit and shortcoming of system to spread in the text the choice and assurance, lords of move the projects spread to move to become soon system of design, bearings of design calculation, the principal axis module choose the control of the school pit, and the principal axis electric motor of use the lubrication, the key spare parts etc. the design process.
　Key words： the number controls the tool machine;The sign type number controls the miller;The lord spreads to move the system;Principal axis module; Bearings; Principal axis electric motor.
