In this text ,it primarily includes the determination of hydraulic system program, the design of the hydraulic manifold block and control system, and the design of the total layout of the contents. When we use the double-head lathe to work the components, because they are relatively long, we plan adopt the way of components fixing, cutting tool revolving and aheading. The circulate pattern of working movement is speeding-^-aheading^-withdrawing^-halting. Meanwhile, each turning head is required to adjust solely. Tell its own tale, it can made the produce needed several working procedure formerly cut completely only once , predigest the working procedure and improve the manufacture benefit enormously.
