The numerical control engine bed is the digital process control engine bed, is one kind of automated engine bed, the numerical control technology is the core which the numerical control engine bed studies, is the manufacturing industry realizationautomation, the network, the flexibility, the integrated foundation. Along with the manufacture technology development, the modern numerical control engine bed with the aid of the modern design technology, the working procedure intensification and the new function part caused the engine bed the processing scope, the dynamicperformance, the processing precision and the reliability had the enormousenhancement.

This article mainly carries on the design to the XK5040 numerical control vertical milling machine , first analyzes the vertical milling machine the processing characteristic and the processing request determines its host parameter, including movement and dynamic parameter; Carry on the host kinematic scheme according to the host parameter and the design request, enters for the system and the control system hardware circuit design. Mainly carries on the host kinematic scheme and enters for the system mechanism design and the ball bearing guide screw andelectric stepping motorshaping and the examination;

Key wordsNumerical control technology;Vertical milling machine;Design
