Brass CNC-Machined Parts That Perform Where Tolerances Matter
Brass CNC machining requires more than clean cuts. The parts you’re sourcing need to fit, assemble, and perform reliably once they’re in service. Whether you’re producing electrical components, fittings, valve bodies, or custom industrial parts, consistency and inspection matter as much as speed.
Founded in 1972, Ephrata Precision provides brass CNC machining from our U.S.-based facility in Ephrata, Pennsylvania. We focus on disciplined process control and clear communication. Our team machines brass with the right tooling, verifies quality through in-process and post-process inspection, and delivers parts that meet spec, ship on schedule, and perform as intended without unnecessary rework.
Common Brass Alloys We Machine
We machine brass alloys selected for performance, machinability, and end-use requirements. Each project is reviewed on a case-by-case basis, but we regularly support customers with common industrial brass grades that machine cleanly and deliver consistent results.
C360 (Free-Cutting Brass)
The most common brass alloy we machine. C360 offers excellent machinability and is frequently used for fittings, connectors, valve components, and other precision-machined parts.
Other Brass Alloys Reviewed Case by Case
Additional brass grades may be selected based on strength, corrosion resistance, electrical properties, or application-specific needs. Material selection is reviewed during quoting to ensure the alloy aligns with your geometry, function, and production goals.
If you’re unsure which brass alloy is right for your part, our team will help evaluate options before machining begins.

Common Brass CNC-Machined Parts and Applications
Brass CNC-machined parts are widely used across industrial manufacturing, OEM equipment, fluid-handling systems, and electrical applications where consistent performance and machinability are critical. We support brass components that must fit correctly and perform reliably in service.
Common brass CNC-machined parts include:
- Fittings and connectors for fluid, air, and mechanical systems
- Valve bodies and internal components where sealing and dimensional accuracy are critical
- Electrical components such as terminals, housings, and conductive parts
- Wear pads and bushings designed for durability and repeatable performance
- Custom industrial components built to meet unique geometry and application requirements
Each project is reviewed individually to ensure machining aligns with how the part will be used in real-world environments.
Why Reliable Brass CNC Machining Starts With Process Control
When brass parts miss specs or arrive late, it impacts more than just one job. Delays and rework affect your entire operation. Reliable brass CNC machining needs consistent setups, proper tooling, and disciplined inspection at every stage.
OEM and product teams working with brass fittings or valve components that must seal correctly the first time to avoid leaks, failures, or costly field issues
Operations managers managing production schedules where one late or out-of-tolerance brass part can stall assembly and push delivery dates
Maintenance and equipment teams are sourcing replacement brass components where fit and reliability directly affect uptime and safety
Supporting Capabilities for Complex Brass CNC Machining
As a longstanding member of both the
National Tooling & Machining Association (NTMA) and the
Polyurethane Manufacturers Association, Ephrata Precision brings decades of hands-on manufacturing experience to complex brass CNC machining projects.
Our core CNC machining capability supports precision brass parts with consistent geometry, repeatability, and reliable inspection across prototype and production work.
How this helps your business: Stable processes that deliver consistent results, not one-off successes.
5-axis machining allows complex brass parts to be produced in fewer setups, improving feature alignment and dimensional accuracy.
How this helps your business: Fewer setups reduce cumulative error and improve part consistency.
Wire EDM enables the precise cutting of intricate features and internal profiles that are difficult to achieve through conventional machining.
How this helps your business: Accurate feature creation without introducing mechanical stress.
Sinker EDM supports detailed cavities and complex internal shapes, including sharp internal corners.
How this helps your business: Greater design flexibility with maintained dimensional control.
Hole drilling EDM produces precise, small-diameter holes where accuracy and repeatability are critical.
How this helps your business: Reliable hole production without compromising surrounding features.
In-house Tool & Die support allows tooling to be built, maintained, and refined internally as requirements evolve.
How this helps your business: Faster adjustments and better long-term repeatability.
Local Manufacturing That Makes Things Easier
Ephrata Precision machines brass CNC parts in Lancaster County, Pennsylvania. From our 56,000-square-foot facility, we ship nationwide and work most often with customers across Pennsylvania and the Mid-Atlantic, where proximity makes a real difference.
Working in the same time zone means clear communication, faster answers, and predictable shipping. Local manufacturing also makes prototyping, design changes, and scaling easier. You get a responsive partner who stays aligned with your timeline from the first part through final delivery.
Brass CNC Machining FAQ
Questions about brass CNC machining? Ephrata Precision Parts has the answers! Our expert team delivers precision parts tailored to you.
Which brass alloy is best for CNC machining?
C360 free-cutting brass is commonly used for CNC machining due to its excellent machinability and consistent results. That said, the best brass alloy depends on your part’s function, geometry, and performance requirements.
Can you hold tight tolerances on brass CNC-machined parts?
Yes. Tolerances on brass CNC-machined parts are achieved through controlled setups, appropriate tooling, and in-process and final inspection. Because tolerance capability depends on part geometry and application, requirements are reviewed on a case-by-case basis to ensure parts meet specifications.
How do you control burrs and edge quality on brass parts?
Burrs and edge conditions are managed through proper tooling selection, machining strategy, and inspection during production. Brass generally machines cleanly when approached correctly, and parts are reviewed before shipment to ensure edge quality meets functional and assembly needs.
