Abstract
Begins from the research CNC milling machine, to profit from the domestic and foreign advanced experiences, design one to use in the dedicated numerical control CNC drilling and milling machine for Grouting pump shaft end cover processing, has satisfied the production and the design request. The entire milling machine including parts of the horizontal and verticalfeed mechanism, columns, beams, base, table and other major groups. The design tasks keeps the entire CNC drilling and milling machine in mind, focus on the design of the bed and slide structure.
Begins from the dedicated numerical control CNC drilling and milling machine's principle of the structure, and discusses the advantages of a rectangle-dovetail shaped sliding railC drilling and milling machine bed structural design and analysis. discusses the use of servo motor and ball screw pair of the advantagesC gantry drilling machine described in detail the structure of the design and verification, and analyzed Addition, a summary of the technical parameters.
In which introduced emphatically the principle of the sliding rail and selection principles, the center is the layout form of vertical drilling milling machine, the key is the bed cross-section selection. Introduce rail production, maintenance and other aspects of the presentation, Including species selection, parameter selection, precision selection, lubrication mode selection and so on.

Keywords : drilling and milling machine, bearing guide screw nut Ball, sliding rail,Clutch plate
