Custom CNC Turn-Mill Stainless Steel Contoured Shaft, Precision Multi-groove Rotary Component | Chenrong Precision

Product Overview

This custom CNC turn-mill stainless steel contoured shaft is a precision rotary part with continuous wavy grooves and square end with locating hole. Manufactured by turn-mill composite machining, it achieves complex curved profiles in one clamping. The bright burr-free machined surface guarantees smooth rotation performance. It is widely used in automation machinery, transmission equipment and precision motion assemblies. We accept custom fabrication according to your CAD drawings or samples, supporting prototype and small batch orders.

FAQ

Q1: What stainless steel grades are available?

A: Standard material is 304 stainless steel. 316 stainless steel is optional for environments requiring superior corrosion resistance.

Q2: What is the advantage of turn-mill machining for this shaft?

A: Turn-mill composite machining can complete cylindrical turning and milling features in a single fixture setup, ensuring high concentricity and consistent precision for complex profiles.

Q3: What drawing formats do you accept for quotation?

A: STEP, IGES, STL, DWG, DXF and PDF. 3D STEP file is preferred for accurate quotation.

Q4: What is your MOQ?

A: Flexible MOQ. We accept 1 piece for prototype, small batch and mass production.

Q5: What tolerance can you achieve?

A: Normally ±0.005~0.02mm. We can meet strict tolerance requirements marked on your drawing.

Q6: How long is the prototype lead time?

A: Normally 5–10 working days for prototype. Bulk lead time depends on quantity and machining complexity.
