Custom CNC Machined Stainless Steel Flange Shaft Precision Turned Integrated Flange Spindle

Product Overview

This custom CNC machined stainless steel flange spindle is manufactured by combined CNC turning and milling. It adopts an integrated one-piece structure, consisting of a circular mounting flange base and a long hollow shaft. Stainless steel material delivers high tensile strength, excellent corrosion resistance and stable rotary performance. Strict control of concentricity and dimensional tolerance ensures smooth rotation and reliable assembly. Widely used in transmission machinery, automation equipment, testing instruments, rotary platforms and precision mechanical systems. OEM & ODM custom service is available based on your 2D/3D drawings or physical samples.

Key Features

1. Premium Stainless Steel Material High mechanical strength, outstanding corrosion resistance, good wear resistance. Stable performance under high-speed rotation and various working environments.
2. Combined CNC Turning & Milling Precision machining to guarantee excellent concentricity, smooth shaft surface without burrs. Tight tolerance meets high-precision rotary requirements.
3. Integrated One-piece Design Flange and hollow shaft are machined from a single blank. Avoid assembly errors, reduce shaking during rotation and improve overall stability.
4. Customizable Specifications Shaft length, inner & outer diameter, flange size, hole layout and thread specifications can be customized according to your technical requirements.
5. Optional Surface Treatments Support polishing, passivation, sandblasting to improve surface finish and anti-corrosion capability.

FAQ

Q1: Can you fabricate this flange spindle according to my CAD drawings?

A: Yes, OEM & ODM are fully supported. Please send your 2D/3D drawings with tolerance requirements for quotation. We can also produce according to your physical samples.

Q2: What stainless steel grades can you supply?

A: 304 stainless steel is widely used for general rotary applications with good cost performance. 316L stainless steel offers superior corrosion resistance for marine, chemical and harsh environments.

Q3: What is your MOQ?

A: MOQ is flexible. We accept prototype small batch orders as well as large volume mass production. Please contact us for detailed quotation.

Q4: Can you polish the shaft surface?

A: Yes. Mirror polishing and matte polishing are available, together with passivation treatment to enhance corrosion resistance.

Q5: What is your normal production lead time?

A: Normally 10–18 working days, depending on shaft length, complexity and order quantity. We will confirm the exact lead time before order confirmation.

Q6: What concentricity can you achieve for this long spindle?

A: Standard concentricity tolerance is ±0.02mm. Higher precision concentricity can be achieved upon special request.

Q7: How do you ensure quality for long shaft parts?

A: We use professional measuring instruments to inspect straightness, concentricity and dimensions. Inspection reports can be provided if required.
