Abstract

An internal flash removal unit which radially cuts flash while it is still hot and relatively soft. A drive motor and reduction gearbox mounted in a housing drive a tooling plate rotatably mounted on the housing. A cutting assembly is mounted on an arm which is pivotally mounted on the tooling plate. A hydraulic actuator causes the arm to move outward and place the cutting assembly into cutting position as rotation of the tooling plate begins.
