Semi-Finish Manufacturing for Rotating Components
Semi-Finish Manufacturing for Rotating Components
Semi-finish machining typically involves removing excess layers of material from forgings prior to the material conditioning process (pre-spinning or overspeed test) and/or the final machining process. Though simple in concept, machining high-strength aerospace disk alloys and performing high-speed spin processing takes real engineering and operational expertise.
Typical semi-finish machining requires a very small margin of error – approximately 0.050 inches of material on all finish dimensions. The capability to produce a consistent and high-quality output in a scalable manner requires having the right equipment, processes and the support of experienced staff. Producing any quantity of non-conforming parts is costly and unacceptable for customers.
