Precision In-Situ Line Boring Services

Restoring Alignment, Minimizing Downtime

At Twinco, we specialize in the rapid and precise restoration of damaged or misaligned bearing bores without the need for disassembly. Using advanced mobile line-boring equipment, we provide on-site machining solutions for internal combustion engines, compressors, steel presses, and other rotating machinery.

Why Choose Twinco for Line Boring?

Damage Assessment & Repair

Bearing bore misalignments often result from overheating, excessive speeds, or improper alignment. Left unaddressed, these issues can lead to shaft damage. Our expert team quickly assesses and restores correct geometry and tolerances in line with OEM specifications.

Mobile Line-Boring Technology

Our compact, high-precision boring equipment allows us to machine bearing bores on-site, eliminating the need for costly and time-consuming removal of engine blocks or major assemblies.

Bore diameters: 100 mm to 1,000 mm

Bore lengths: Up to 18 metres

Tolerances: Within hundredths of a millimetre

Engineered for Speed and Accuracy

Our boring system, set up with engine-specific adapters and optical alignment tools, ensures perfect coaxiality. Adjustable motor feed and multi-tip cutting heads deliver accurate results, every time.

Efficient Cap Machining

To ensure circularity and standard diameters, we pre-machine the bearing caps directly on-site, eliminating the need for workshop intervention—even in remote locations.
