Methods of milling a piece of raw steel stock into a machine-ready piece of steel

A method of milling a piece of raw steel stock into to a machine-ready piece of steel comprising:

• presenting a piece of raw steel stock having a first surface, a second surface on the opposite side as the first surface, and at least one protrusion at least 5 inches in length;
• presenting a magnetic chuck with a top surface configured to support the piece of raw steel stock for milling via magnetic capabilities;
• determining where on the top surface of the magnetic chuck the second surface of the piece of raw steel stock will be supported for milling of the first surface thereof;
• 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 are relatively evenly distributed under a perimeter of the piece of raw steel stock and within 2 inches of the perimeter and at least one solid pole extension will be disposed under each protrusion;
• before milling the first surface:
• locating a bow in the piece of raw steel stock;
• and arranging an additional solid pole extension between the top surface and where the bow in the piece of the raw steel stock will be supported for milling;
• arranging multiple mobile pole extensions on the top surface to support the second surface of the piece of raw steel stock for milling, each of the multiple mobile pole extensions having a top portion that is biased away from the top surface of the magnetic chuck;
• placing the second surface of the piece of raw steel stock onto the top portion of each of the multiple mobile pole extensions and the solid pole extensions, such that each of the mobile pole extensions and each of the solid pole extensions support the piece of raw steel stock;
• activating the magnetic capabilities of the magnetic chuck, thus locking the top portion of each of the multiple mobile pole extensions in place at a position matching a contour of the second surface of the piece of raw steel stock;
• and
• milling the first surface of the piece of raw steel stock to a desired flatness.

A method of milling a piece of raw steel stock down into to a machine-ready piece of steel comprising:

• presenting a piece of raw steel stock having a first surface, a second surface on the opposite side as the first surface, and at least two holes extending from the first surface through to the second surface;
• presenting a magnetic chuck with a top surface configured to support the piece of raw steel stock for milling via magnetic capabilities;
• determining where on the top surface of the magnetic chuck the second surface of the piece of raw steel stock will be supported for milling of the first surface thereof;
• 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 under a perimeter of the piece of raw steel stock and within 2 inches of the perimeter and at least one solid pole extension will be disposed between the at least two holes;
• before milling the first surface:
• locating a bow in the piece of raw steel stock;
• and arranging an additional solid pole extension between the top surface and where the bow in the piece of the raw steel stock will be supported for milling;
• arranging multiple mobile pole extensions on the top surface to support the second surface of the piece of raw steel stock for milling the first surface thereof, each of the multiple mobile pole extensions having a top portion that is biased away from the top surface of the magnetic chuck;

• activating the magnetic capabilities of the magnetic chuck, thus locking the top portion of each of the multiple mobile pole extensions in place at a position matching a contour of the second surface of the piece of raw steel stock;
• and
• milling the first surface of the piece of raw steel stock to a desired flatness.
