Abstract
A core machine is arranged to automatically refine the shape of a sand core upon removal of the core from the machine. The core machine uses a core box to form a core. After formation of the core and separation of the core box halves a shaping member is moved into a space between the core box halves. As the core is ejected from the core box and removed from the machine it passes through the shaping member which refines the shape of the core. The machine may also be used for dimensional tolerancing about the parting line of the core box.
