ABSTRACT:
A hydraulic circuit for use on a turning machine (10) having a quill (32) which is movable to an extended and retracted position for detecting, through pressure drop, when the quill (32) is fully retracted or extended and engaging a workpiece. The quill (32) is positioned by a hydraulic cylinder (40) which is operated from a hydraulic power supply (60). A pressure actuated switch (48) is connected to one of the operating ports on the hydraulic cylinder (40) and a orifice (70) is connected to the same port. By detecting when the pressure sensitive switch (48) is activated with respect to positioning of the hydraulic cylinder (40) proper functioning of the quill (32) can be determined. A timer (90) circuit is provided for determining that the pressure sensitive switch (48) changes position within a set time period after the hydraulic circuit is activated to change position of the quill (32).
