Portable Weld Milling Machine Apparatus and Methods of Using the Same

An apparatus for milling a first railroad rail comprising:

• a support structure comprising a first clamp extending from a first side of the support structure and configured for clamping the support structure to a first railroad rail, a second clamp extending from the first side of the support structure and configured for clamping the support structure to the first railroad rail, and a third clamp extending from a second side of the support structure and configured for clamping the support structure to a second railroad rail running parallel to the first railroad rail;
• a first linear guide running longitudinally and parallel to the first and second railroad rails;
• a second linear guide running laterally and perpendicular to the first and second railroad rails, wherein the second linear guide is on the first linear guide;
• a support sub-structure attached to the second linear guide;
• and
• a milling tool extending from the support sub-structure comprising a railroad rail profile milling head, the milling tool comprising a vertical lifting mechanism for moving the railroad rail profile milling head vertically,
• wherein movement of the support sub-structure on the second linear guide allows for lateral movement of the railroad rail profile milling head laterally and movement of the support sub-structure and the second linear guide together on the first linear guide allows for longitudinal movement of the railroad rail profile milling head longitudinally.
