The body valve was a case where the engineers were considering a casting. Mac Machine worked with them on print changes that would make the part well suited to a “Hog-Out”, drastically reducing the lead time and part cost.
Once qualified on the mill, we took the part to our HT40 lathe where we created the i.d. features critical to the “in-line” features that are so important to a butterfly housing, but we also created outside contour features and hogged away material to assist the final mill operation to reduce cycle time.
