Core characteristics and technical advantages of crankshaft machining

1.Whole process precision machining system

Using German HELLER, Japan MAZAK multi-axis CNC machine tools, to achieve the main shaft neck, connecting rod neck and other key parts of the micron precision (±0.005mm), combined with JUNKER high-speed CBN grinding machine synchronous grinding, surface roughness Ra≤0.2μm; According to the requirements of different working conditions, integrated rolling strengthening, high-frequency quenching and ion nitriding process, fatigue strength increased by more than 40%, Marine engine crankshaft salt spray corrosion life extended by 3 times.

2.Advantages of scale and flexible manufacturing

More than 30 fully automated production lines support the rapid flow from blank to finished product (single line beat ≤15 minutes), modular design compatible with 300mm to 6m length, 10kg to 2 tons of weight crankshaft, 72 hours to complete non-standard product process development, to meet the Caterpillar mining machinery, Cummins X series and other diverse needs.

3.Strict quality verification system

The largest crankshaft fatigue laboratory in Asia certified by China CNAS can simulate more than 10 million cyclic load tests to ensure that products meet B10 life standards such as Caterpillar C9 and Cummins ISX15. Coordinate measuring machine (accuracy ±1.5μm), direct reading spectrometer and Schenck dynamic balancing machine (G6.3 class) to achieve 100% full inspection, key parameters can be traced for 20 years.

4.Cold hardening of crankshaft rounded corners by Hegensett rolling equipment to increase fatigue strength by more than 40%; Combined with induction hardening technology, the surface hardness reaches 55-62HRC, and the wear resistance is increased by 30%.

Honesty offers high-load, long-life, lightweight crankshaft solutions for customers around the world to continuously enable the efficient and stable operation of construction machinery, Marine power and generator sets.
