To date, INGERSOLL has produced milling machines capable of machining parts over 100 feet in length. Stress relieving their machines’ components can be a challenge. The VSR process was used to stabilize a 59 foot long milling machine gantry. Stress relieving the workpiece both before and after rough machining (total time < 4-hours) resulted in a dimensional accuracy of 0.0036″ over the entire length, and only 0.0018″ in the critical center portion of the component where spindle travel occurs.
