With the constant development of science and technology, the numerical control lathe has entered practical stage of taking too at home. But at present in our country, a lot of state-run factories have a batch of old lathes, if we transform to them on the basis of old lathes and mix them with numerical control technology. We can not only decrease the costs, but also raise the service lives of the old lathes. However, our topics of graduation project is to switch the ordinary milling machines to turret numerical control machining center, which have the functions of boring, milling, and drilling. They can realize to the transfer of boring, milling and drilling in the short time in the condition of being not artificial to transfer knives. It can not only improve production efficiency and machining accuracy, but also decrease costs. I’m responsible for the whole overall arrangements of lathe and the design of eight axles turret numerical control machining center. I apply the knowledge of man-machine engineering and model of the products into the whole overall arrangements of lathe. The operation principles of eight axles turret numerical control machining center is to insert cutters in the axles according to the arrangement of working procedure in advance of machining, and after inject the oil into the jar of center, the pressure make eight axles turret to be transferred entirely, this make it to realize the function of transfer knives automatically. This set of simples numerical control machining center have used the frequency conversion technology which was developed in recent years too, thus this improved the scientific and technological content among them. Because the domestic state-run factories all face the situation that the old lathes need eliminates now, so there are market prospects very much to carry on the transformation of numerical control on the basis of old lathe, thus it is practical for us to carry on this graduation project. KEY WORDS: the technology of numerical control, eight axles turret, frequency conversion technology, change the knife automatically IV - -
