ABSTRACT:
A feed mechanism for a machine tool having an improved stop mechanism which includes a movable stop, a stationary stop, and a rotatable control member. The stationary stop is located on a rotational path of the movable stop which is freely rotatable about a handle shaft. The control member, which can be rotated together with the handle shaft, is adapted to rotate the movable stop together therewith except through a predetermined angular extent, such that the handle shaft for feeding a movable unit of the machine tool may be rotatable more than the movable stop by the predetermined rotational extent.
