To support the walls during thin wall milling, keep a widecross section behind it. We recommend utilizing a "stepped down" approach, which divides the total wall height to manageable depths while working each side of the wall. The Axial Depth of Cut (ADOC) dimension will vary depending on the material (and its hardness) being cut.
