CNC Turned And Milled Stainless Steel Flange Shaft Sleeve With Internal Thread

CNC Turned and Milled Stainless Steel Flange Shaft Sleeve with Internal Thread

Product Overview

This CNC Turned and Milled Stainless Steel Flange Shaft Sleeve with Internal Thread is a high-precision mechanical component designed for reliable connection, positioning, and load transmission in industrial assemblies. Manufactured using advanced turn-mill compound machining technology, this component integrates a flange base, a shaft sleeve body, and a precision internal thread into a single, seamless unit—eliminating the need for multiple separate parts and significantly improving assembly efficiency and structural integrity.

Advantages of Turn-Mill Compound Machining

Traditional machining often requires multiple setups—first turning the sleeve, then milling the flange and drilling holes on separate machines. This introduces alignment errors and increases production time.

With turn-mill compound machining:

• All operations (turning, milling, threading, drilling) are completed in a single clamping cycle.

• Concentricity and angular positioning are inherently precise.

• Lead times are significantly reduced.

• Unit cost is lowered for medium to high volumes.

Applications

This flange shaft sleeve with internal thread is widely used in:

• Industrial Automation: Mounting bases for sensors, actuators, and robotic arms.

• Hydraulic & Pneumatic Systems: Connection seats for cylinders, valves, and fittings.

• Automotive & Heavy Machinery: Shaft positioning sleeves, mounting adapters.

• Medical Equipment: Precision stainless steel components requiring cleanability and corrosion resistance.

• Marine & Chemical Processing: Components exposed to moisture, salt spray, or corrosive media.

FAQ - Frequently Asked Questions

1. What materials are available for this flange shaft sleeve?

We primarily offer stainless steel grades, including:

• SS304: Good corrosion resistance and formability, suitable for general industrial applications.

• SS316 / SS316L: Enhanced corrosion resistance, ideal for marine, chemical, and medical environments where exposure to salt, chlorine, or acidic conditions is a concern.

• Other materials such as carbon steel, brass, or aluminum can also be accommodated upon request.

2. What thread types can you machine?

We support a wide range of internal thread specifications, including:

• Metric: M3 to M30 and above, with standard or fine pitch

• Unified: UNC, UNF, UNEF

• Pipe threads: BSPP, BSPT, NPT

• Custom threads: Non-standard sizes or special thread forms can be machined according to your drawings

Thread fit classes (e.g., 6H for metric, 2B for unified) can be controlled to meet your assembly requirements.

3. What is the advantage of turn-mill compound machining compared to traditional machining?

Traditional machining typically involves:

• Turning on a lathe (for the sleeve and flange OD/ID)

• Moving to a milling machine (for flange features, holes, or flats)

• Multiple setups = increased alignment error and longer lead time

With turn-mill compound machining:

• All operations are completed in one clamping cycle

• Concentricity between the thread, sleeve bore, and flange is inherently accurate

• Lead times are shorter

• Cost per part is reduced for medium to high volumes

4. What tolerances can you achieve?

We maintain standard machining tolerances of ±0.01 mm to ±0.05 mm for most dimensions. For critical features such as:

• Internal thread pitch diameter

• Flange perpendicularity

• Sleeve bore concentricity

We can achieve tighter tolerances (down to ±0.005 mm) depending on the design, material, and quantity. Final tolerance specifications should be indicated on your drawing.

5. Do you provide custom sizes?

Yes. This is a custom-machined component. We manufacture strictly according to:

• Customer drawings (2D CAD with dimensions and tolerances)

• 3D models (STEP, IGES, or SolidWorks files)

• Physical samples (reverse engineering available)

There are no minimum order quantity restrictions for prototypes, and we offer OEM and ODM services.

6. What surface treatments are available?

Depending on the application, we offer:

• As machined: Clean finish with visible tool marks

• Polished: Smooth, reflective finish for aesthetic or sanitary requirements

• Passivation: Removes free iron from the surface, enhancing corrosion resistance (standard for stainless steel)

• Bead blasting: Uniform matte finish

• Electropolishing: Improves surface smoothness and corrosion resistance

• Nickel or zinc plating: Available for non-stainless steel materials

7. What is your typical lead time?

Lead times vary based on material availability, complexity, and current production schedule. Rush orders can be accommodated upon discussion.
