Abstract: A method of milling a piece of raw steel stock comprising: arranging a minimum of four solid pole extensions on top surface segments of a magnetic chuck such that the solid pole extensions are relatively evenly distributed under a piece of raw steel stock and within 2 inches of a perimeter of the piece of raw steel stock; arranging multiple mobile pole extensions beneath the piece of raw steel stock and on every other top surface segment of the magnetic chuck under the piece of raw steel stock that is not occupied by the solid pole extensions but beneath the piece of raw steel stock, each of the multiple mobile pole extensions having a biased top portion that contacts the piece of raw steel stock; and milling the piece of raw steel stock with a face mill that generates steel chip as swarf.

Abstract: A method of milling a piece of raw steel stock comprising: presenting a piece of raw steel stock having a first surface and a second surface having a perimeter; presenting a magnetic chuck with a top surface configured to support the piece of raw steel stock for milling with magnetic capabilities; arranging a minimum of four solid pole extensions on the top surface to support the second surface of the piece of raw steel stock for milling of the first surface thereof such that the solid pole extensions will be relatively evenly distributed beneath the perimeter of the second surface; arranging multiple mobile pole extensions on the top surface to further support the second surface; placing the second surface onto the multiple mobile pole extensions and the solid pole extensions; activating the magnetic capabilities of the magnetic chuck; and milling the first surface to a desired flatness.
