Brass Turning Part
Brass turning parts are machined to customer print for assemblies that demand close fits, corrosion resistance, and stable conductivity. NOWARUN turns and mills these custom components from brass and copper down to a machining tolerance of +/-0.01 mm. Secondary finishing options include blasting and oxidizing depending on your enclosure or assembly requirements. Every batch is manufactured to order from your technical drawing rather than delivered from ready stock.

Key Benefits
- Machining tolerance of +/-0.01 mm keeps concentricity and critical seating dimensions accurate on turned features
- Manufactured from brass or copper to ensure corrosion resistance, thermal transfer, and consistent electrical conductivity
- Turned, milled, and ground to your exact drawing rather than restricted to fixed catalogue dimensions
- Surface finishing options like blasting and oxidizing give clean finishes for visible or sealed assemblies
- Multiple export packaging options protect bare threads and tight tolerances during overseas transport
- Certified quality management systems ensure batch consistency and dimensional adherence on every production run
Problems It Solves
- Stock brass hardware does not meet custom interior thread profiles or external seating steps
- Inconsistent turning tolerances lead to leaks or loose assembly fits in non-ferrous housings
- Off-the-shelf catalog brass parts use unknown alloy standards that fail in service
- Burrs and rough surface finishes damage mating seals and o-rings during field assembly
Who It Is For
- Procurement engineers sourcing custom turned brass parts directly from an OEM drawing
- Mechanical design engineers who need non-ferrous components with +/-0.01 mm dimensional tolerances
- Equipment builders replacing proprietary turned brass fittings that are unavailable in standard catalogues
- Contract assembly operations requiring repeatable batches of finished brass or copper precision parts
Application Scenarios
- Fluid and pneumatic assemblies requiring corrosion-resistant brass turned fittings and tight seal faces
- Electrical equipment needing turned copper and brass components with stable conductivity and precise mounting threads
- Machine construction applications requiring custom non-ferrous bushings, standoffs, or threaded inserts
- Food processing equipment parts needing clean, non-corroding brass turned components machined to print
- Agricultural equipment sensors and instrumentation assemblies requiring +/-0.01 mm turned brass bodies
Technical Features
- CNC turning combined with secondary milling and grinding operations
- Precision tolerance capability held down to +/-0.01 mm
- Material processing across brass and copper alloys to customer specification
- Surface finishing capabilities including abrasive blasting and oxidizing treatments
- Clean-cut threads, tapers, and stepped internal bores machined to drawing
Materials
- Brass for general machinability, mechanical wear resistance, and corrosion-resistant hardware
- Copper for assemblies demanding elevated electrical conductivity and thermal dissipation properties
- Custom alloy compositions processed according to the mechanical specifications on your engineering print
How It Is Made
- 1
Technical drawing and dimensional tolerance review before raw bar stock procurement
- 2
CNC precision turning of outer diameters, faces, internal bores, and thread geometry
- 3
Secondary CNC milling and grinding for off-axis features, flats, or tighter fits
- 4
Surface treatment application including blasting or oxidizing to match customer finish requirements
- 5
Final dimensional inspection and thread gauging before packing for export shipment
Quality Control
- Critical dimensions and tolerances checked against drawing requirements down to +/-0.01 mm
- Surface finish verification following blasting or oxidizing treatments
- Thread integrity and bore fit checked using standard GO/NO-GO gauges
- Compliance verification aligned with ISO 9001:2008, ISO/TS 16949, SGS, and ROHS standards
Customization Options
- Machined directly to custom 2D prints or 3D CAD files
- Choice of base material between brass, copper, or customer-specified grades
- Custom surface preparation including media blasting or oxidizing finishes
- Flexible export packaging configurations using cartons, crates, boxes, or PP bags
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Standard catalogue brass parts | Stock hardware is ready immediately, but custom turned parts match your exact stepped bore and thread geometry |
| Stainless steel turned parts | Stainless steel provides higher mechanical yield strength, but brass cuts faster, reduces tool wear, and conducts heat better |
| Die cast brass components | Die casting is cost-effective for huge volumes, but CNC turning achieves +/-0.01 mm precision without expensive tooling fees |
Use Guide
- Provide complete 2D engineering drawings with dimensional tolerances and thread standards marked
- Specify the exact brass or copper material grade needed for your application
- Indicate whether surface blasting, oxidizing, or bare turned finish is required
- Confirm the delivery packaging type to prevent thread dinging during ocean or air transit
- Inspect mating chamfers and sealing faces before torquing into final mechanical assemblies
