Suzhou Krosino Mechatronic Technology Co., Ltd. provides precision CNC machining for industrial gears and pulleys. In power transmission systems, the geometric accuracy of tooth profiles and pulley grooves is vital for efficiency, noise reduction, and long-term durability. We combine high-precision CNC turning, milling, and specialized hobbing capabilities to manufacture reliable components for automation, drive systems, and mechanical assembly.
For gears and pulleys, tooth profile symmetry and concentricity are the primary quality indicators. We manage these tolerances through integrated multi-setup machining and rigorous in-process inspection.
| Component Feature | Typical Functional Tolerance |
|---|---|
| Gear Tooth Profile / Pulley Groove Geometry | ±0.02mm to ±0.05mm (Ensures smooth torque transfer) |
| Bore Concentricity | 0.02mm TIR (Prevents vibration and axial run-out) |
| Keyway Accuracy | ±0.02mm (Standard fit for shafts) |
Q1: How do you ensure gear noise reduction during machining?
Gear noise is often caused by profile inaccuracies. We utilize high-precision CNC gear-cutting and hobbing techniques to ensure tooth profiles are generated with high fidelity to the theoretical involute curve, minimizing mesh impact and vibration.
Q2: What heat treatment services do you offer for these parts?
For high-load applications, we provide surface induction hardening on gear teeth to increase wear resistance. We also perform through-hardening or case-hardening for components that must endure high rotational speeds and shock loads without fatigue failure.
Q3: How do you maintain balance in high-speed pulleys?
We prioritize concentricity during the CNC turning process. By keeping the bore and the pulley groove aligned within a 0.02mm TIR range, we ensure that the mass distribution remains balanced, which is essential for stable operation at high RPM.
