Abstract
A mining machine includes a frame having a guide rail, the guide rail having a central portion. The mining machine also includes a shoe having a recessed area that defines a roller path, the shoe further having a drive lug, wherein the central portion of the guide rail is configured to be disposed within the recessed area. The mining machine also includes a cutting tool coupled to the frame and positioned such that the cutting tool is configured to abrasively remove material from the drive lug as the drive lug passes by the cutting tool.

A mining machine comprising:
- a frame;
- a shoe having a recessed area that defines a roller path, the shoe further having a drive lug;
- and
- a cutting tool coupled to the frame and positioned such that the cutting tool is configured to abrasively remove material from the drive lug as the drive lug passes by the cutting tool,
- wherein the frame includes a guide rail having a central portion configured to be disposed within the recessed area, wherein the guide rail has a side portion extending from the central portion, wherein the cutting tool is coupled to the side portion.
A guide rail for a frame of a mining machine, the guide rail comprising:
- a central portion having a convex outer surface;
- a side portion extending from the central portion;
- and
- a cutting tool coupled to the side portion;
- wherein the cutting tool is configured to abrasively remove material from a drive lug of a shoe as the shoe moves along the guide rail.
A cutting tool configured to be coupled to a frame of a mining machine, the cutting tool comprising a surface configured to abrasively remove material from a drive lug of a shoe as the shoe moves along the frame, the cutting tool further comprising the frame, wherein the cutting tool is integrally formed as a single piece with the frame.
A mining machine comprising:
- a frame including a guide rail;
- a shoe having a recessed area that defines a roller path, the shoe further having a drive lug;
- a cutting tool coupled to the frame and positioned such that the cutting tool is configured to abrasively remove material from the drive lug as the drive lug passes by the cutting tool, the cutting tool being coupled to a portion of the frame that is separate from the guide rail.
A guide rail for a frame of a mining machine, the guide rail comprising:
- a central portion;
- a side portion extending from the central portion;
- and
- a cutting tool removably coupled to the side portion;
- wherein the cutting tool is configured to abrasively remove material from a drive lug of a shoe as the shoe moves along the guide rail.
