Summary: The program that economy of milling machine of lifting platform of introductory X5030 vertical numerical control transforms and debug a note. Keyword: Numerical control of milling machine of X5030 vertical lifting platform transforms the utilization rate to improve facility and manufacturing efficiency, the milling machine of X5030 vertical lifting platform that group of northeast spy steel checks to was purchased 1976, use MCS-51 series sheet piece machine the numerical control device that is core, it is actuating device to undertake transforming to the fore-and-aft, transverse orgnaization of milling machine into electric machinery with the pace, comprise an economy CNC Milling, control principle sees a picture 1. Use Ao Wei of the Changchun City of limited company of accurate test equipment electro-hydraulic the JKW system of servo type, system of this numerical control with MCS-51 sheet piece personal computer is core, modular structure. There is the computer inside box board, power source board, interface board and drive board. Use switch power source, stabilized voltage range is wide, interference rejection capability is strong, its pace enters electric machinery high frequency torsion of the output when moving is big, still can use the computer to install origin. This system has higher performance/price ratio, the numerical control that suits this milling machine very much is changed transform. The mechanical share of milling machine of X5030 vertical lifting platform has transforming realizing numerical control through the fore-and-aft, transverse orgnaization of milling machine. To make sure milling machine can be controlled by the computer, tear open above all go vertical, transverse clutch and vertical, transverse handwheel, handwheel end enters electric machinery to connect through a pair of gear and pace, use a pace to control workbench horizontal stroke, fore-and-aft shift into electric machinery. The perpendicular feed of workbench still can move implementation with the hand, make of structure of milling machine drive alter decrease as far as possible, when cent malfunctions, numerical control ministry still can use manual semi-automatic operation. The discovery in using, because fore-and-aft guide screw grows milling machine, use frequent, transverse guide screw to bear load is big, answer to change its ball guide screw. Use ball guide screw, must use double nut to eliminate clearance and adjust tighten force beforehand, must change to its stiffness, lead at the same time stability of total sum of errors undertakes checking computations.
