Brass Machining Part
Brass machining parts are manufactured to customer print using CNC turning, milling, and grinding processes to achieve tolerances down to ±0.01 mm. NOWARUN machines these components from brass or copper alloys with surface finishing options including blasting and oxidizing. Every batch is produced under an ISO 9001 and ISO/TS 16949 certified quality management system to support demanding fluid handling, electrical, and mechanical assemblies.

Key Benefits
- Machining tolerance held to ±0.01 mm keeps tight fits reliable across brass turned and milled profiles
- Choice of brass and copper stock accommodates specific mechanical, corrosion, and conductivity needs
- Combined turning, milling, and grinding capabilities allow complex prismatic and turned shapes in one shop
- Surface finishing options like blasting and oxidizing provide specified cosmetic appearance or surface protection
- Production certified to ISO 9001 and ISO/TS 16949 ensures traceable and repeatable manufacturing processes
- Custom components made entirely to drawing rather than limited by catalogue stock sizes
Problems It Solves
- Catalogue brass fittings do not fit custom housing envelopes or proprietary thread configurations
- Loose tolerances from standard turned part vendors cause fluid leaks or inconsistent sub-assembly fit
- Sourcing turned and milled brass parts separately creates coordination issues and mismatched mating interfaces
- Uncertified suppliers fail to provide documentation compliant with ISO 9001 and ISO/TS 16949 audit rules
Who It Is For
- Procurement engineers sourcing custom brass and copper machined components to technical drawings
- Machine builders needing consistent ±0.01 mm tolerances on precision brass turned parts
- Equipment OEMs replacing catalogue brass fittings with custom-profile non-ferrous components
- Project managers requiring contract machining verified against ISO 9001 or ISO/TS 16949 standards
Application Scenarios
- Machine construction where tight-tolerance brass bushings or guide components require precise fits
- Fluid control and valve assemblies requiring leak-tight turned brass fittings and milled bodies
- Electrical and grounding assemblies taking advantage of copper or brass conductivity and tight tolerances
- Food processing and agricultural machinery requiring non-sparking or corrosion-resistant non-ferrous parts
- Replacement brass parts machined to drawing for equipment rebuilds and maintenance overhauls
Technical Features
- Machining capability across CNC turning, milling, and grinding operations
- Dimensional tolerance down to ±0.01 mm on brass turned parts
- Material processing for both brass and copper alloys
- Surface treatments including media blasting and oxidizing per specification
- Manufactured according to ISO 9001, ISO/TS 16949, SGS, and ROHS compliance standards
Materials
- Brass for precision turned bushings, valves, and wear-resistant machinery components
- Copper for parts demanding high thermal and electrical conductivity alongside accurate tolerances
- Customer specified grades of brass and copper alloys based on technical prints
How It Is Made
- 1
Drawing evaluation to verify dimensions, ±0.01 mm tolerances, and material specifications
- 2
Raw brass or copper bar stock preparation and cutting
- 3
CNC turning of outer diameters, bores, and critical sealing surfaces
- 4
CNC milling of flats, slots, cross-holes, or complex mounting contours
- 5
Precision grinding when surface finish or tighter diameter control is indicated
- 6
Surface treatment application such as blasting or oxidizing followed by final inspection
Quality Control
- Dimensional verification against drawing limits ensuring tolerance held within ±0.01 mm
- Compliance management maintained under certified ISO 9001:2008 and ISO/TS 16949 systems
- ROHS and SGS compliance verified for export non-ferrous material requirements
- Protective packaging in PP bags, cartons, or crates to prevent thread and surface damage
Customization Options
- Manufactured entirely to 2D prints or 3D CAD files provided by the customer
- Choice of raw material between various brass grades and pure copper
- Surface finishing matched to drawing requirements including blasting and oxidizing
- Custom packaging configuration ranging from individual PP bags to wooden crates
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Off-the-shelf standard brass fittings | Custom machining matches non-standard threads and compact envelopes but requires drawing review and setup lead time |
| Die cast brass components | CNC turned and milled parts achieve tight ±0.01 mm tolerances without the upfront tooling expense of casting molds |
| Stainless steel machined parts | Brass offers easier machinability and natural corrosion resistance, but lower tensile strength under extreme structural loads |
Use Guide
- Provide a detailed 2D engineering drawing indicating critical dimensions and ±0.01 mm tolerance zones
- Specify the exact brass or copper alloy grade needed for your application
- Indicate whether surface treatment such as blasting or oxidizing is required
- State packaging preferences such as individual PP bags to protect sensitive threads during transit
- Confirm any compliance documentation requirements such as ROHS, SGS, or ISO/TS 16949 certificates
