How Is Line Boring Done?

Our line boring and repair process involves two steps. First, welding addresses significant wear or gouges in the pivot point hole. We fill these gaps, essentially building up material to bring the hole back to its original size and shape or specifications.

Once we fill the hole with weld material, line boring takes over. This specialized machine with a precise cutting tool removes a tiny, even layer of material from the entire bored surface—both the original metal and the new weld. This ensures perfect alignment along a common center line.

Why Is Mobile Line Boring Better Than Replacing Old Parts?

Replacing entire components can be expensive, especially for large equipment. Our mobile line boring allows repairs to be done on-site, saving costs on parts, transportation, and downtime.

Here are a few other reasons why line boring is better than opting for a replacement:

  • Preserves original parts: Line boring repairs the existing parts, maintaining the integrity of the original equipment design and potentially improving longevity.
  • Minimized Downtime: Our services bring the repair directly to the equipment, reducing downtime compared to transporting the entire machine (or sending new parts overseas).
  • Precision alignment: Our line boring machines ensure highly precise realignment of worn holes, whereas replacing worn parts might require additional adjustments.

How Does a Line Boring Machine Work?

The line boring machine fixes misaligned or slightly warped holes (bores) in machinery with a multi-pointed cutting tool. Secured on a spindle, this tool is fed through the existing bore. As it rotates and advances, the cutting edges remove small amounts of material from the inner surface.

By carefully controlling the cutting tool’s movement and depth, the machine ensures a perfectly straight and uniformly sized bore. This process restores the hole’s precise alignment and diameter, allowing for optimal fit and function.
