Line Boring Bar Reconditioning

Precision Restoration for Line Boring Bars

Line boring bars are essential for maintaining tight tolerances in engine block, crankshaft, and large component machining. Over time, wear, vibration, and thermal stress degrade performance. The experienced technicians at ACTS recondition these components using  high-precision processes to ensure repeatable, high-accuracy operation.

Line Boring Bar Reconditioning Services Typically Include:

• Complete Disassembly & Cleaning – Removal of built-up debris, coatings, and contaminants.
• Straightness & Runout Inspection – Checking for bending, warping, or axial misalignment.
• Bearing Surface Rebuilds – Restoring or replacing contact surfaces for smooth operation.
• Bar Straightening or Remanufacturing – Precision alignment and shaft re-machining as required.
• Balancing & Vibration Control – Ensuring stability during high-speed operations.
• Final Inspection & Testing – Runout, dimensional checks, and documentation of restored specifications.
