Rotational Pre-Growth Services

The Issue

Rotors forged from today’s powder metal alloys will experience plastic growth due to centrifugal force loading on the component during operation.

Why It Matters

A substantial growth can cause loss of fit in the end-use assembly, or unwanted vibration and/or performance.

What You Can Do

Spinning rough forgings to achieve a specified amount of plastic pre-growth before final machining is a well-established method to produce the highest quality and dimensionally stable parts.
