01. Brass Materials & Machining Specifications
We support custom CNC turned brass pins and related precision brass components. Material selection and machining requirements can be specified according to your drawings.
| Item | Available Options / Specifications |
|---|---|
| Brass materials | C36000, C26000 (listed in our general CNC turning material range) |
| Additional machining materials | Brass, bronze and copper |
| Standard machining tolerance | ±0.05 mm |
| Tighter dimensional tolerance | Up to ±0.01 mm for selected critical dimensions, depending on part geometry, material and machining conditions |
| Surface roughness | Ra 0.8–1.6 μm for fine turning |
| Improved surface finish | Ra 0.4 μm by polishing |
| Production basis | Customer drawings, samples or technical requirements |
Material grades and dimensional tolerances are confirmed against the specific part requirements before production.
02. Custom Brass Pin Configurations & CNC Turning Options
We manufacture custom turned brass components with different profiles and machining features.
| Custom Feature | Available Machining Options |
|---|---|
| Pin profiles | Cylindrical and stepped configurations |
| External features | Grooves, shoulders, chamfers and machined flats |
| Internal features | Drilled and bored holes |
| Threading | Internal and external threads |
| End configurations | Facing, chamfering and cut-off |
| Additional operations | Reaming and selected milling features |
Custom dimensions, feature positions and machining details are based on your technical drawings. Milling operations can also be considered for parts requiring flats, slots or hexagonal features.
03. Precision Machining & Quality Inspection
Our CNC turning workflow includes first-piece inspection, in-process dimensional checks, tool-wear monitoring and final inspection.
Available inspection equipment includes:
| Inspection Equipment | Inspection Purpose |
|---|---|
| CMM | Dimensional measurement |
| Optical projector | Profile and dimensional inspection |
| Calipers and micrometers | External dimensions |
| Bore gauges | Internal dimensions |
| Thread gauges | Thread inspection |
| Surface roughness tester | Surface finish measurement |
For selected critical dimensions, 100% inspection can be arranged according to the inspection requirements. Other dimensions may be inspected through sampling.
04. CNC Machining Factory & Bulk Supply
Our manufacturing facilities support CNC turning and complementary machining operations for custom precision metal components.
Available equipment includes CNC lathes, 3-axis, 4-axis and 5-axis machining centers, CNC milling machines, drilling machines and tapping equipment.
Our general CNC turning service supports different order quantities:
| Production Type | Reference Quantity |
|---|---|
| Prototype machining | 1–10 pcs |
| Small-batch production | 100–1,000 pcs |
| Larger production orders | 10,000+ pcs |
These are general service references rather than fixed minimum order quantities for every brass pin. Actual production arrangements depend on part complexity, drawing requirements and order quantity.
05. Custom Brass Pin Samples & Production Support
We support prototype development, small-batch manufacturing and repeat production based on customer drawings or physical samples.
For general CNC turning orders, the published reference lead times are:
| Order Type | Reference Lead Time |
|---|---|
| Samples | 5–7 working days |
| Batch production | 3–4 weeks |
Actual lead times are confirmed according to material availability, machining complexity, inspection requirements and order quantity.
06. Request a Quote from a Custom Brass Pin Manufacturer
Send us your existing drawings, sample photos or basic dimensional requirements to discuss your custom CNC turned brass pins.
Please include the following information where available:
- Pin dimensions and structural details
- Brass material grade
- Critical dimensional tolerances
- Surface finish requirements
- Prototype or production quantity
We will review the machining requirements and provide feedback on manufacturing feasibility and quotation based on your specifications.
