The abstract lathe is in the machine manufacture uses a most widespread kind of engine bed, mainly uses in processing each kind of rotation surface (for example: In the outer annulus cylinder, the circular conical surface, the ring groove, the solid of revolution formation surface and so on) and the solid of revolution end surface, some lathes also can process the thread. In common machine shop, because the majority components all have the rotation surface, simultaneously lathe itself multi-purpose is strong, the use cutting tool is simple, therefore the lathe occupies in the metal-cutting machine tool the proportion is big. But in all lathe class engine bed, is most widespread by the horizontal lathe application. Because the horizontal lathe craft scope is quite widespread, may in the turning the outer annulus cylinder, the circular conical surface, the ring channel, the solid of revolution formation surface, the turning end surface and each kind of commonly used metric system, the British system, the mold notational system, the pitch system thread, but also may carry on drills the center bore, the drill hole, the broaching, reams, work and so on tapping, wrap thread and knurling. This article elaborated a 12 level of rotational speed C6132 horizontal lathe headstock design process, the headstock uses to support the main axle and to cause it revolving. The main axle is the hollow structure, appendices and so on its front end male cone installment three support on both sides the work piece, front end in the conical surface uses for to install the apex, the tall and slender hole may penetrate the long good material, in the box only then the level speed change, its main axle gearshift mechanism imposition in is far away the main axle in the independent gear box, reduces the vibration and the quantity of heat which in the gear box the biography moving parts produce to the main axle the influence.
