Abstract  Milling machine numerical control transformation may greatly enhance automatic capability and productivity level of equipments and fulfill the higherrequirements of enterprises on equipments. Through plan analysis of XA5032 milling machine transformation and design calculation of feeding transmission system, by adopting WA-21M NC system, NC transformation of milling machines is completed; selection principle and selection plan of NC system, servo electrical machinery choice, electrical system NC transformation plan and system control softwarecomposition and work principle are elaborated. After transformation, step precision in X,Y,Z is 0.005,0.005,0.01 mm/setp; axial location accuracy is 0.015 mm; repetition location accuracy is 0.008 mm. Processing precision and productivity are greatly increased, which demonstrates the success of transformation. Meantime, it provides a feasible way for enterprises to enhance rate of NC.
