Precision Brass Parts, Built to Your Specifications
Brass CNC Machining Services
Custom brass CNC machining for precision components with tight tolerances, clean finishes, and consistent quality. We machine brass parts from prototypes to low-volume production based on your drawings.
Brass CNC Machining
Brass is a versatile alloy known for excellent machinability, corrosion resistance, and conductivity. Our CNC machining services deliver precision brass parts for plumbing, electrical, marine, instrumentation, and decorative applications.
We machine a wide range of brass alloys with tight tolerances and consistent quality using advanced 3-axis, 4-axis, and 5-axis CNC milling and turning centers.
- High precision with tight tolerances
- Excellent surface finish and dimensional stability
- Complex geometries and fine details
- Rapid prototyping to mass production
- Short lead times and on-time delivery
- Strict quality control with full inspection reports

Brass CNC Machining FAQs
What brass grades do you machine?
We commonly machine C260, C360, C385, C464, C272, and C230 brass. Other grades can also be sourced based on your drawings and application requirements.
Which brass grade is best for CNC machining?
C360 is the most widely used grade for CNC machining because it cuts cleanly, produces short chips, and provides a good surface finish. Other grades may be more suitable when corrosion resistance, strength, or formability is more important.
What tolerances can you achieve on brass parts?
Standard tolerances follow ISO 2768 unless otherwise specified. Critical dimensions can typically be held to ±0.01 mm, depending on the part geometry, size, and machining process.
Can you manufacture both brass prototypes and production parts?
Yes. We machine one-off prototypes, low-volume orders, and repeat production parts. The machining process and inspection plan are adjusted according to the required quantity.
What surface finishes are available for brass parts?
Available finishes include as-machined, polishing, brushing, bead blasting, nickel plating, chrome plating, tin plating, and passivation. Finish availability depends on the brass grade and part requirements.
Can you machine threaded brass components?
Yes. We produce internal and external threads for fittings, connectors, inserts, valves, and other custom brass parts. Metric, UNC, UNF, NPT, BSP, and custom thread specifications are available.
How do you inspect brass CNC machined parts?
We use CMMs, micrometers, calipers, thread gauges, pin gauges, and optical measuring equipment. Inspection reports and material certificates can be provided when required.
What information is needed for a brass machining quote?
Send your 2D drawings or 3D CAD files, brass grade, quantity, tolerance requirements, surface finish, and any inspection requirements. STEP, STP, IGES, X_T, DWG, DXF, and PDF files are accepted.
