Frequently Asked Questions

Shaft manufacturing involves several key steps: material selection, design engineering, CNC machining (turning, milling, grinding), heat treatment, surface finishing, and quality inspection. Our process ensures precision tolerances, optimal surface finish, and reliable performance for your specific application requirements.

We use a wide range of materials including carbon steel (1018, 1045, 1144), alloy steel (4140, 4340, 8620), stainless steel (303, 304, 316, 416), bronze and brass alloys, aluminum alloys, and specialty alloys (Inconel, Hastelloy). Material selection depends on application requirements, load conditions, and environmental factors.

The best steel depends on your application. 4140 alloy steel offers excellent strength and toughness for general applications. 4340 provides superior fatigue resistance for high-stress applications. Stainless steel grades like 316 offer corrosion resistance. We help you select the optimal material based on your specific requirements.

Our shaft manufacturing process includes: 1) Design and engineering consultation, 2) Material selection and procurement, 3) CNC turning and milling for basic geometry, 4) Precision grinding for tight tolerances, 5) Heat treatment for enhanced properties, 6) Surface finishing and coating, 7) Quality inspection and testing, 8) Final documentation and delivery.

Shafts are constructed through precision machining processes. We start with high-quality raw material, use CNC turning to create the basic cylindrical shape, apply milling for keyways or splines, perform grinding for precision tolerances, apply heat treatment for strength, and finish with surface treatments. Each step is carefully controlled for quality assurance.
