摘要：
The present invention provides an apparatus to repair gouged out and damaged leading and trailing edges of gas turbine engine blades, particularly fan blades, by cutting away a curved section including the damaged area and forming a blend radius along the repaired edge. The apparatus includes a unique machine tool guide having an adjustable cutting depth guide and mountable to a hand held machine tool driver, such as a 90 degree angle head air motor, that drives a rotary cutter.
