Read On1. Automatic Table Feed Mechanism. This is the simple mechanism in the shaper machine. The automatic table feed mechanism is simple and it is started by activating a ratchet wheel and it is mounted at cross-feed screw. This mechanism ensures the same motion of cross-feed screw after every stroke. 2.
Read OnThe motion of head-stock spindle is also transmitted to the feed gearbox through the gearing at the end of the bed. The drive is then transmitted through the feed gear box; selectively to the lead screw or the feed shaft, depending on whether the machine is being used for screw cutting or plain turning.

Read OnThe main motion of the engine lathe is the rotation motion of the spindle, and the feed motion is the linear movement of the tool. Feed is usually expressed by the movement of the tool per spindle, in M / R. When turning threads, there is only one compound main motion, namely screw motion, which can be decomposed into spindle rotation motion and tool movement.
