Connectors and Fittings
Machined connector bodies, adapters, compression fittings, cable hardware, and fluid or pneumatic interfaces can be reviewed for threads, bores, sealing faces, and wrench flats.
Brass CNC Machining for Functional Components
Brass is selected for machinability, conductivity, corrosion behavior, appearance, and reliable threaded or sliding interfaces. We review brass CNC machining projects from the released model and drawing, including material condition, part geometry, quantity, finish, deburring, inspection, and packaging.
Bushings and Sleeves
Brass bushings, spacers, sleeves, pins, and wear-related components are planned around bore size, fit, length, surface condition, and assembly context.
Conductive Components
Terminals, contact hardware, grounding pieces, and other conductive parts should identify contact surfaces, plating or finish, burr limits, and functional inspection needs.
Choosing CNC Turning or Milling for Brass
Process choice follows the part geometry. CNC turning is typically efficient for round connectors, fittings, sleeves, pins, and threaded adapters. CNC milling is useful for flats, pockets, cross-holes, slots, mounting faces, and multi-face features. A turned blank may receive secondary milling or drilling when the design combines rotational and prismatic features. Setup strategy, workholding, tool access, quantity, and inspection datums are confirmed during quotation.
Turning Features
Outside diameters, bores, grooves, shoulders, threads, tapers, and cutoff features can be reviewed from the drawing.
Milling Features
Wrench flats, cross-drilled holes, pockets, slots, keyways, and mounting patterns may require indexed or multi-face milling.
Combined Operations
When a connector or fitting needs both turned and milled features, the process sequence is planned around datums and repeatable clamping.
Material Grade and RFQ Confirmation
Brass grade must be confirmed by the drawing or buyer-approved specification; it should not be inferred from a generic material label. State the standard, grade, temper or condition, bar or plate form, acceptable alternatives, certificate requirements, and any restrictions related to lead, plating, or application. Material availability and machinability can affect tooling, surface appearance, chip control, and cost, so the approved specification is part of the quotation record.
Specification
Identify the exact brass grade, condition, dimensions, and traceability or certificate requirement.
Application
Explain whether the part is a connector, bushing, fitting, conductive element, decorative component, or another function so critical features are understood.
Alternatives
List acceptable substitutions only if your engineering team approves them; the final material remains the released drawing requirement.
Surface Finish, Threads, Burrs, and Inspection
Brass parts can show different visual and dimensional results depending on tool condition, grain, handling, and finishing. Define whether surfaces are machined, polished, brushed, plated, lacquered, or otherwise treated, and identify cosmetic zones. Threads should include standard, size, class or fit, start, depth, and gauging method. State edge-break or burr limits, especially around cross-holes, sealing faces, electrical contacts, and internal bores. Inspection can cover critical dimensions, thread gauges, go/no-go checks, surface finish, sampling, and reports through our quality control workflow.
Thread and Fit Control
Provide thread standards, mating parts, functional fit, and post-finish dimensional requirements.
Deburring
Call out edge breaks, burr height, sharp-edge restrictions, cleaning, and particle limits where the part enters an assembly.
Inspection Evidence
Define first-article, sampling, dimensional report, material certificate, or functional check requirements before production.

Materials Comparison
When corrosion, strength, weight, or finish changes the design, compare the project with aluminum CNC machining or stainless steel machining.
Production Quantity
Prototype, low-volume, and repeat orders can be reviewed with the low-volume machining team.
Brass CNC Machining FAQ
What brass parts can be CNC machined?
Common project types include connectors, fittings, bushings, sleeves, spacers, threaded adapters, terminals, and other compact precision parts. The drawing determines the final process, grade, tolerance, and inspection requirements.
Should brass parts use CNC turning or milling?
CNC turning is generally suited to round parts such as fittings, sleeves, pins, and connectors. CNC milling is useful for flats, pockets, cross-holes, slots, mounting features, and multi-face geometry. Combined operations can be planned when needed.
Which brass grade do you supply?
The brass grade, temper or condition, form, and certificate requirement must be confirmed from the drawing or RFQ. We do not assume a fixed supply range without reviewing the application and approved material specification.
