Abstract
The basic machines that are designed primarily to do turning, facing and boring are called lathes. Very little turning is done on other types of machine tools, and none can do it with equal facility. Because lathe can do boring, facing, drilling, and reaming in addition to turning, their versatility permits several operations to be performed with a single setup of the workpiece. These accounts for the fact that lathes of various types are more widely used in manufacturing than any other machine tool.
Lathe Construction: The essential components of a lathe are depicted in the block diagram. These are the bed, headstock assembly, tailstock assembly, carriage assembly, quick-change gear box, and the lea & crew and feed rod.
On most lathes the tool post actually is mounted on a compound rest. This consists of a base, which is mounted on the cross slide so that it can be pivoted about a vertical axis, and an .upper casting. The upper casting is mounted on ways on this base .so that it can be moved back and forth and controlled by means of a short lead screw operated by a hand-wheel and a calibrated dial.
The turntable is fastened to the middle slip board by bolts. Loose the nut, we can make the turntable rotated in the level for no mater what angle. The minor slip board can move along the rail of turntable for a short distance. When the turntable rotates an angle, the minor slip board will make a sidelong displacement carrying.
Generally, the turntable locates between the up and down knife rest, it is the up knife rest¡¯s oriented member. When we want to cut the cone by using the minor, we can rotate the turntable.
This essay will cover an integrated analyzing and demonstrates about the turntable¡¯s function, mechanical workout techniques and the design of clamp used. It will give a detailed illuminate about the technical procedure, set down a reasonable technical routings, and work out a complete set of card for mechanical workout techniques.
