In the world of heavy machinery, such as marine engines, power plants, and industrial compressors, a small crankshaft defect can lead to costly breakdowns. Traditional crankshaft repair requires full engine disassembly, transporting the crankshaft to a workshop, machining, and reinstallation—all of which eat into time, budget, and productivity.
That’s where in situ machining and polishing of the crankshaft come in. Performed directly within the engine block, this technique restores crank journals and crankpins without removal, minimizing downtime, labor, and logistical headaches. On site, centimeter-level precision meets OEM standards.
What Is Insitu Machining & Polishing of Crankshaft?
- In‑place repair: A portable crankshaft grinding-polishing unit is mounted around the crank journal or link pin while the crankshaft stays installed
- Precision grinding & polishing: Removes microns of material to restore geometry, followed by smooth finishing—achieving tolerances within 10–25 µm and RA surface quality per OEM specs.
- Final quality checks: Use tools like MPI, micrometers, and vibration analysis to ensure balanced, defect-free journals.
Why Our Approach Stands Out?
We’ve combined best-in-class workflows from global industry leaders and insights from leading providers, delivering:
- Portable machines for 50–700 mm journals, lightweight & compact
- 24/7 mobilizable teams ready for emergency onsite response
- Standard-compliant surface finishing (10–25 µm accuracy, OEM RA)
- Advanced testing tools: MPI, vibration analysis, hardness checks, post-process QA
