ABSTRACT:
An air release stock stop for detecting the end of a bar stock during a machining process on a turning machine. The air release stock stop includes a pivot member hingedly connected to a base member by a shaft, an activation member adjustably connected through the pivot member and a valve unit activated by the pivot member within the base member. The base member fastens to the body of a turning machine such that the connected pivot member and activation member align with the spindle(s) on the turning machine. Preferably a bar stock end fixed within the spindle(s) comes in contact with the activation member as the bar stock is fed out to be machined. The force applied by the bar stock as it contacts the activation member causes the pivot member to rotate about the shaft, activating the valve unit to indicate proper feed for the machining process.
