Design of CK6132 CNC Lathe Overall and Feed Drive
【Abstract】：With the rapid development of machinery manufacturing, in order to further improve the teaching production of small and medium-sized CNC lathe price, improve the spindle speed, increase the rigidity of the original CNC lathe made a certain structural improvement designed to not only meet the teaching Use can also be used for the production of semi-refined, finishing. The subject in the design, CK6132 lathe can not only choose the stepper motor, and can choose the servo motor. Select the appropriate feed drive screw support, ball screw preload and bearing selection and lubrication is also very important, while the feed-driven installation how to ensure accuracy, in this subject have the corresponding Syria. The completion of the feed-related design issues, to meet the teaching production of small and medium-sized CNC lathe processing related parts requirements, while the machine also has a good price, and ultimately achieve the purpose of the design of integrated training.
【Key words】: CK6132 CNC lathe; overall design; feed drive components design
