EXPLANATION:There are several feed mechanisms to make the tool carriage and cross slide move automatically and to change the DIRECTION of their movement. Some important mechanisms are as follows.LEAD screw is a long thread bar mounted just below and PARALLEL to the bed ways. The lead screw is engaged with the carriage during the thread cutting operation to move the carriage to a CALCULATED distance.Feed Rod is placed between the lead screw on the front side of the bed. It is a long shaft which has a keyway along its length. The power is transmitted from the spindle to the feed rod through tumbler gears and a gear train. It is useful in providing feed movement to the tool carriage except for thread cutting and to move cross slide. A worm mounted on the feed rod enables the power feed movements.
