The lathe class machine tool mainly was used in to process each kind of rotation surface, like inside and outside periphery, the circular cone surface, take shape the rotation surface and the gyre end surface and so on, some lathes also can process whorl. Because the most machine part has the rotation surface, lathe versatility broader, therefore in machine shop, lathe application extremely widespread, accounts for the proportion in the metal cutting bed to be biggest, approximately composes the machine tool main station number 20% ~ 35%.
As the main turning processing machine tool, the CA6140 machine tool was widespread used in the machine-finishing profession, it is used in turning inside and outside the turning the round cylinder, taper and gyre, turning each kind of metric system, the British system, the modulus and the diameter festival thread, and can carry on the drill hole and pulls work and so on fuel tank. The lathe bed width to the common lathe , has a higher rigidity, the facade of the lead after middle frequency quenching, so it will be durable. The machine tool main axle aperture is big, the operation agile centralism, the apron is equipped with quickly moves the organization. machine tool structure rigidity and transmission rigidity quite high, the power use factor quite is also high, is suitable for the force high-speed cutting.
The horizontal-type machine tool processing object, mainly is the axis class components and the diameter not too big plate class components, therefore uses the horizontal-type layout. Its major component includes: headstock, tool slide, tailstock, feedbox, apron and bed. This design mainly aims at the headstock of the CA6140 machine tool .The headstock of machine tool is a quite complex transmission part. The design content mainly includes determines the machine tool’s main parameter, Draws up the transmission plan and the transmission scheme, Calculated and examined the main spare part，And used specialized charting software to carry on the components design and processing.
