ABSTRACT:
A feed amount setting device for a machine tool is provided wherein an axially slidable follower rod is urged to contact a plate cam rotated by a feed device of the machine tool and is formed with an operating face for pivoting a lever arm, such that movement thereof is transmitted to a switch actuation plunger in a predetermined magnification ratio. A lever support carrying the lever arm is adjustable in a direction parallel with the follower rod, and the plunger is formed with a flat face extending in parallel relation with the adjusting direction of the lever support for engagement with the lever arm, so that the feed amount of the feed device, depending on a signal from a switch element, is variable without adjusting the mounting position of the switch element.
