ABSTRACT:
Apparatus for positioning a machine tool in relation to a workpiece comprises a support for the tool actuated by a fluid ram, with a control member carried by the support on a parallelogram linkage and arranged to operate a servo-valve associated with the ram. The controller is actuated at selected positions by a selected one of a number of pre-selector members adjustably located on a reference member which also engages the work. Each pre-selector member has an extendable roller controlled by a small fluid ram and when the roller runs off the end of the control member the ram stops and the machine tool is then in position.
