Line Boring

  • WHat WE do

Precision repair of heavy equipment

Line boring is a precision machining process used to repair or modify the inner diameter of cylindrical holes (bores) in equipment, typically heavy machinery or engines. These holes are often used to house bearings, shafts, or other components that must align perfectly for the machinery to function correctly.

Restore worn bores

Over time, the bores in machines like excavators, bulldozers, or engines wear out or become oval-shaped. Line boring restores them to their original size and shape.

Ensure alignment

Bores must be perfectly aligned for components like shafts to work smoothly. Line boring realigns them with precision.

Modify bores

It brings the bore back to spec for diameter, geometry, and surface finish, sometimes by cutting to a controlled oversize to accept a bushing/sleeve or new bearing.

Weld and re-bore

If a bore is too damaged, technicians weld the hole shut and then re-machine it to spec. Fixing bores to machined true, to size, and on the correct centerline.

  • why line boring

Preserving mechanical integrity, performance, and reliability

Line boring is vital for preserving the mechanical integrity, performance, and reliability of heavy equipment and precision systems. It helps avoid catastrophic failures, costly replacements, and prolonged downtime.

  • Saves Time and Money
    Instead of replacing large expensive parts or entire machines, line boring repairs the worn areas which minimizes downtime, reduces labor costs, and extends the life of machinery.
  • Enables On-site Repairs
    Mobile line boring allows technicians to bring precision machining to the job site, eliminating the need to transport heavy equipment to a machine shop.
  • Supports Preventive Maintenance
    Regular line boring during scheduled maintenance can prevent costly breakdowns by keeping bores within tolerance, ensuring that parts fit and move correctly.
  • Essential for Heavy Industries
    Industries like construction, mining, marine, and manufacturing rely on line boring to keep critical equipment running safely and efficiently under extreme conditions.
