In addition ,the thesis deals with amount of components devices and calculations ,including :(1) Choice of the main shaft and disposal of transmission , by doing so to ensure the accuracy of components machining in process when the main shaft rotating;(2)The device and check of the transmission shaft ,so it can assure the rigidity of the shaft is allowable ;(3) Gear device and calculations ,check the performance in the strength and rigidity of it ;headstock is a very important part in this thesis ,the design of it here not only ensures the rationality 、equipoise and stability of the motion of the slipway ,but also satisfies the requirements of different work environment .

液压装置的设计液压滑台、定位夹紧装置均为液压控制。并采用了许多液压控制阀，保证了运动的平衡性，循环性和精确性。另外，本文还涉及到大量的设计和计算，包括：（1）、主轴的选择和传动布置，以保证加工过程中被加工零件的精度；（2）、传动轴的设计和校核，以保证轴的刚度；（3）、齿轮的设计、计算，对齿轮的强度和刚度进行校核；多轴箱部分是本次设计的重要环节，本次设计中它的设计既要保证工作台的运动的合理、平衡和准确，又要满足工作要求。

And call it the craft course. In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the locomotive of processing , this process , and the entering the giving amount of the lathe, cut

在制定工艺过程中，要确定各工序的加工顺序和该工序需要的工步，加工该工序的机车及机床的进给量，切削深度，主轴转速和切削速度，该工序的夹具，刀具及量具，还有走刀次数和走刀长度，最后计算该工序的基本时间，辅助时间和工作地服务时间。
