Abstract
Main research φ 400 mm economical middle-grade precision numerical control crosswise of lathe, author of this text of summary, enter give design of organization and transform. Among them, have described two kinds of different entering horizontal and manually to the device, namely two kinds of different plans of design mainly. Compare through the pluses and minuses to two kinds of different plans of design , according to raising and orientate the precision , orient the factors, such as precision,etc. repeatedly, confirm plan of design two as the plan of design designed this time finally. In design in calculating, have lathe horizontal to enter give main composition part of organization to numerical more control authors of this text mainly: Ball guide screw vice, bring, bring wheel, exchange servo electrical machinery, vice guide and transfer to location knife rest, etc. design calculating or selecting type automatically in step in step. Among them guide screw vice to ball taking, exchange servo electrical machinery and transfer to location design of knife rest calculate and selecting type act as and expound the fact especially automatically in step. In addition author of this text go on and design to each spare part also, draw all part picture and lathe horizontal to enter give installation diagram of organization numerical control this. It is reliable that this is of simple structure, can apply to similar all kinds of numerical control lathes . [资料来源：http://www.THINK58.com]
