Suzhou Krosino Mechatronic Technology Co., Ltd. specializes in the precision CNC machining of high-performance custom shafts. Whether for high-speed rotational applications, industrial transmissions, or structural motion control, we provide tailored shaft solutions that emphasize concentricity, straightness, and fatigue resistance. Our manufacturing process ensures that every shaft meets rigorous dimensional and material integrity standards for reliable mechanical performance.
Shaft performance is defined by its ability to maintain axis stability under load. Our process prioritizes the alignment of bearing seats, splines, and shoulder features to minimize vibration.
| Shaft Feature | Typical Functional Tolerance |
|---|---|
| Bearing Seating Diameter | ±0.005mm to ±0.01mm (Critical for interference fits) |
| Total Concentricity / Run-out | 0.01mm - 0.02mm (Ensures vibration-free rotation) |
| Surface Finish (Ra) | 0.4μm to 0.8μm (Optimizes seal and bearing life) |
Q1: How do you prevent long shafts from warping during machining?
For long or slender shafts, we employ steady rests during CNC turning to prevent deflection. We also use stress-relief cycles after initial rough machining to stabilize the material structure before finalizing dimensions.
Q2: What materials are recommended for high-torque shafts?
We recommend alloy steels such as 42CrMo or 40Cr. These materials offer excellent yield strength and can be induction hardened on key wear surfaces to provide a durable shaft that resists torsion and bending.
Q3: Can you machine custom splines or keyways?
Yes, our CNC equipment is capable of milling precise keyways and hobbing standardized splines. We ensure that these features are perfectly indexed with the shaft axis, preventing power transmission imbalance.
