5 Axis CNC Stainless Steel Parts
Dongguan Henghui Hardware Co., Ltd. is a China-based CNC machining manufacturer providing custom CNC machining for stainless steel components. We combine 5-axis machining capabilities with a range of stainless steel grades, precision machining processes, and surface finishing options. We accept 2D drawings, 3D CAD files, and physical samples for custom part evaluation, from prototype development to batch production. Our 5-axis CNC machining service covers stainless steel components with complex three-dimensional geometries, including multi-angle surfaces, deep cavities, undercuts, and curved features. The machining configuration uses three linear axes (X, Y, Z) and two rotary axes, with simultaneous 5-axis machining available for suitable part geometries.

Our 5-axis CNC machining service covers stainless steel components with complex three-dimensional geometries, including multi-angle surfaces, deep cavities, undercuts, and curved features.
The machining configuration uses three linear axes (X, Y, Z) and two rotary axes, with simultaneous 5-axis machining available for suitable part geometries.
Our CNC machining processes include:
- 3-axis, 4-axis, and 5-axis CNC milling
- CNC turning
- Precision drilling and boring
- Rigid tapping and thread machining
- Deburring and secondary machining
The machining process is selected according to the part geometry, drawing requirements, and production needs.
2. Stainless Steel Materials and Machining Specifications
We offer the following stainless steel material options for custom stainless steel CNC machined parts.
| Material | Available Grade |
|---|---|
| Stainless Steel | 303, 304, 304L |
| Stainless Steel | 316, 316L |
| Precipitation-Hardening Stainless Steel | 17-4PH |
| Stainless Steel | 316Ti |
Machining Specifications
| Parameter | Available Specification |
|---|---|
| Standard dimensional tolerance | ±0.05 mm |
| Precision machining tolerance | Up to ±0.01 mm, depending on part geometry and requirements |
| Standard surface roughness | Ra 1.6–3.2 μm |
| Precision surface roughness | Ra 0.8–1.6 μm |
| CNC turning maximum diameter | 320 mm |
| CNC turning maximum length | 750 mm |
| CNC milling maximum dimensions | 1000 × 600 × 500 mm |
The listed turning and milling dimensions refer to the stainless steel machining capabilities, not a guaranteed working envelope for every 5-axis machine. Specific tolerances and machining feasibility are evaluated against individual part drawings.
3. Stainless Steel Surface Finishing Options
Surface finishing can be selected according to the required appearance and surface condition.
Available options include:
- Passivation (ASTM A967)
- Electropolishing
- Mechanical polishing
- Sandblasting
- Bead blasting
- Brushed finishing
These options can be specified as part of the custom machining requirements.
4. Custom Machining, Quality Inspection and Production
We accept customer drawings and physical samples for custom stainless steel part manufacturing.
Drawing and File Formats
Supported file formats include:
- STEP
- IGES
- X_T
- DWG
- DXF
Our engineering support includes drawing review and Design for Manufacturability (DFM) suggestions.
Quality Inspection
Our stated quality control process includes:
- Raw material verification
- In-process inspection of critical dimensions and monitoring of tool wear
- Final dimensional inspection
Available inspection equipment includes CMM, height gauges, micrometers, optical measuring equipment, and surface roughness testers.
Material documentation and dimensional inspection requirements can be discussed according to the project.
Prototype and Batch Production
| Production Stage | Typical Lead Time |
|---|---|
| Prototype machining | 3–7 days |
| Batch production | 15–20 days |
Lead times depend on part complexity, material availability, and order quantity. MOQ is determined according to part complexity, material requirements, and production quantity rather than a single fixed minimum.
