Portable Weld Milling Machine Apparatus and Methods of Using the Same

Abstract

A portable rail weld milling machine apparatus comprises a metal frame that incorporates a motor with a rotary carbide tool that is able to lock to a rail or rails for stability. The apparatus houses the required guides and motors to maneuver the tool on a plurality of axes with computer numerical control (“CNC”). The CNC programming is able to control the carbide tool such that the welded rail can be milled to proper profile on the entire running surface, including the top, the field side, and the gauge side of the ball of the rail.

AI Technical Summary

Benefits of technology

The present invention provides a portable rail weld milling machine apparatus that can accurately restore the profile of a rail after welding of the same. It can improve the accuracy of the profile restoration while being easy to operate without causing stress or strain on an operator. Additionally, it reduces the possibility of improper profile restoration and minimizes damage or injury caused by dust and sparks.

Problems solved by technology

Indeed, irregularities in the head of a rail may interfere with the proper rolling of rail vehicles thereon.

Oftentimes, the operation of existing rail grinding machines tend to force the operator into an awkward position and placed an undesirable amount of stress on his or her shoulders and back region, causing fatigue over time and enhancing the likelihood of improper restoration of the rail profile.

Moreover, using rotary grinding tools in the manner described above may cause the production of a large of amount of sparks that can be thrown in multiple directions, increasing the likelihood of injury and / or damage caused by fire.
