| Parameter | Details |
|---|---|
| Process | CNC Turning + CNC Milling (Turn-Mill Compound / Combined Process) |
| Material | Stainless Steel (SS304, SS316, SS316L, or customer-specified grades) |
| Thread Type | Metric (M series), UNC, UNF, BSPP, BSPT, NPT, or custom specifications |

Traditional manufacturing methods typically require separate operations:
First, turning on a lathe to create the sleeve body and flange diameter
Second, transferring to a milling machine for flange features, bolt holes, or flats
Multiple setups introduce alignment errors and increase production time
All operations are completed in one clamping cycle
Concentricity between the internal thread, sleeve bore, and flange mounting face is inherently accurate
Angular positioning of flange holes relative to thread orientation is precisely controlled
Lead times are significantly reduced
Unit costs are optimized for medium to high volume production

Quantity (prototype, trial order, or estimated annual volume)
Special Requirements (packaging, certifications, inspection documentation)
Our engineering team reviews each inquiry to provide manufacturability feedback and optimize design for cost-effective production.
1. What is CNC turning and milling combined processing, and why is it used for this product?
CNC turning and milling combined processing (also known as turn-mill compound machining) is a manufacturing method that performs both turning and milling operations on a single machine in one clamping cycle.
For this flange internal thread sleeve connection seat, this process is critical because:
Turning creates the cylindrical sleeve body, flange diameter, and internal bore
Milling machines the flange face, bolt holes, flats, or other non-rotational features
Threading can be performed via tapping or thread milling within the same setup
By completing all operations without repositioning the workpiece, we achieve superior concentricity between the internal thread, sleeve bore, and flange mounting face—a key requirement for precision connection applications.
2. What stainless steel grades are available?
We offer a range of stainless steel grades to suit different application requirements:
| Grade | Characteristics | Typical Applications |
|---|---|---|
| SS304 | Good corrosion resistance, excellent formability, cost-effective | General industrial, food equipment, architectural |
| SS316 / SS316L | Superior corrosion resistance, especially against chlorides and chemicals | Marine, chemical processing, medical devices, pharmaceutical |
| SS303 | Enhanced machinability, slightly reduced corrosion resistance | High-volume precision machining, automatic lathe work |
| 17-4PH | High strength, hardness, and good corrosion resistance | Aerospace, defense, high-stress mechanical connections |
Other materials including carbon steel, brass, aluminum, or specialty alloys can be accommodated upon request.
3. What internal thread types can you machine?
We support a comprehensive range of internal thread specifications:
| Thread Category | Examples |
|---|---|
| Metric | M3, M4, M5, M6, M8, M10, M12, M16, M20, and up to M30+; coarse and fine pitch |
| Unified Inch | UNC (Unified National Coarse), UNF (Unified National Fine), UNEF |
| Pipe Threads | BSPP (British Standard Pipe Parallel), BSPT (British Standard Pipe Taper), NPT (National Pipe Taper) |
| Custom / Special | Non-standard diameters, special pitches, multi-start threads, or custom thread forms per drawing |
Thread fit classes (e.g., 6H for metric, 2B for unified) can be controlled to meet your assembly requirements.
4. What tolerances can you achieve with the combined turning and milling process?
Due to the single-setup nature of turn-mill compound machining, we maintain tight tolerances across all features:
| Feature | Typical Tolerance |
|---|---|
| Outer diameter / Inner diameter | ±0.01 mm to ±0.05 mm |
| Internal thread pitch diameter | 6H (metric) or 2B (unified) standard; tighter upon request |
| Flange perpendicularity | ≤0.02 mm |
| Concentricity (thread to bore) | ≤0.01 mm to ≤0.03 mm depending on size and complexity |
| Bolt hole position | ±0.05 mm to ±0.10 mm |
For critical applications, we can achieve tighter tolerances down to ±0.005 mm. Final tolerance specifications should be clearly indicated on your drawing.
5. Can you manufacture to custom dimensions and designs?
Yes. This is a custom-machined component. We manufacture strictly according to:
2D engineering drawings (PDF, DWG, or DXF formats) with dimensions, tolerances, and thread specifications
3D CAD models (STEP, IGES, SolidWorks, or other formats)
Physical samples (reverse engineering services available)
We offer OEM and ODM services with no minimum order quantity for prototypes. Our engineering team can also provide design for manufacturability (DFM) feedback to optimize your design for cost and quality.
6. What surface treatments and finishes are available?
Depending on the application requirements, we offer various surface finishes:
| Finish | Description |
|---|---|
| As Machined | Clean finish with visible tool marks; suitable for functional applications where appearance is not critical |
| Polished | Smooth, reflective finish for aesthetic or sanitary requirements |
| Passivation | Chemical treatment that removes free iron from the stainless steel surface, enhancing corrosion resistance (standard for most stainless steel parts) |
| Bead Blasting | Uniform matte finish that conceals tool marks and provides a consistent appearance |
| Electropolishing | Electrochemical process that improves surface smoothness, corrosion resistance, and cleanability—ideal for medical, pharmaceutical, and food contact applications |
7. How do you ensure quality control?
Our quality management system is ISO 9001:2015 certified. The quality control process includes:
First Article Inspection (FAI) : Complete dimensional inspection of the first piece against all drawing specifications before production begins
In-Process Inspections : Operators monitor critical dimensions at defined intervals during machining
Final Inspection : Using CMM (Coordinate Measuring Machine), optical comparators, thread gauges, plug gauges, and surface roughness testers
Material Certification : Mill test reports and material certifications available upon request
Inspection Reports : Full dimensional reports can be provided with each shipment
All thread features are inspected using go/no-go thread gauges to ensure proper fit and function.
8. How are the parts packaged for shipment?
We provide secure packaging to ensure parts arrive in perfect condition:
Individual protection : Anti-rust paper or VCI (vapor corrosion inhibitor) bags for stainless steel and other metal parts
Internal packaging : Foam-lined boxes or compartment trays for precision components to prevent surface damage
Outer packaging : Standard export cartons, plywood cases, or pallets depending on order size and destination
Custom labeling : Barcode labels, part number markings, or assembly-ready trays available upon request
