CNC Orbital Crankshaft Grinding on Crankpins & Journals
OEM-Level Crankshaft Restoration | 3–5 μm Accuracy | Superior Surface Finish
With over 7 years of experience, KIMI delivers OEM-level crankshaft restoration through advanced Orbital CNC Grinding Technology. Our facility is capable of processing crankshafts up to 7.5 meters long, 1.3 meters in turning diameter, and 15 tonnes in weight, while achieving exceptional journal geometry and surface finish.
What Is CNC Orbital Crankshaft Grinding?
Orbital CNC Grinding Technology enables highly accurate restoration of crankpins and journals by continuously synchronizing the grinding wheel with the crankshaft’s machine surface.
Achieving 3–5 μm accuracy, superior surface finish, and OEM-compliant restoration, this advanced machining method delivers exceptional roundness, cylindricity, concentricity, and precise geometry throughout the grinding process.
The result is improved bearing contact conditions, reduced vibration, lower mechanical stresses, and restoration of crankshaft dimensions to OEM tolerances, ensuring maximum reliability and extended service life.
