Common questions about shaft and pin manufacturing
Turned shafts are machined on a CNC lathe and typically achieve tolerances of ±0.01mm with surface finishes around Ra 0.8-3.2µm. Ground shafts undergo an additional grinding operation after turning, achieving much tighter tolerances (±0.002mm or better) and superior surface finishes (Ra 0.1-0.4µm). Grinding is essential for bearing surfaces, close-tolerance fits, and applications requiring minimal runout.
Yes, we provide complete heat treatment services including through hardening, case hardening (carburizing), induction hardening, and nitriding. For precision applications, we typically rough machine, heat treat, then finish grind to final dimensions. This compensates for any distortion during heat treatment and ensures dimensional accuracy is maintained.
Standard CNC turning achieves ±0.01mm. Precision grinding can achieve ±0.002mm or better, with h6/h7 tolerance fits common for bearing applications. For ultra-precision applications, we can achieve tolerances to ±0.001mm with specialized grinding operations.
Long shafts are machined between centers to maintain straightness. After heat treatment, precision straightening operations are performed if needed. Final grinding between centers ensures excellent concentricity and minimal runout (TIR typically < 0.01mm). We can verify straightness and runout with CMM or dedicated runout fixtures.
Yes, we manufacture involute and straight-sided splines to ANSI B92.1, DIN 5480, and other international standards. Splines can be cut, hobbed, or ground depending on quality requirements. We can produce both external and internal splines with quality classes suitable for aerospace applications, with complete inspection documentation.
We have no minimum order quantity. We can efficiently produce single prototype shafts for development work or production volumes in the thousands. Our flexible manufacturing approach allows us to handle both low-volume custom work and high-volume production runs.
Yes, all shafts and pins include material test reports (MTR) with full traceability. For aerospace applications, we provide AS9102 First Article Inspection Reports, Certificate of Conformance, heat treatment certifications, and hardness test reports. Additional testing such as magnetic particle inspection or ultrasonic testing can be provided as required.
Standard turned shafts can be completed in 1-2 weeks. Ground shafts requiring heat treatment typically take 3-4 weeks to allow for heat treatment cycles and post-heat-treat grinding. Rush services are available for urgent requirements. Production volumes are quoted based on quantity and complexity.
