CNC Machined Brass Parts: Product Overview

Brass is the most widely used material for CNC precision turning parts after aluminum.

Why CNCPioneer for CNC Machined Brass Parts?

Coordinate geometry, material, finishing and inspection around the part's intended function.

Swiss CNC Guide Bushing

Plan support and setup around critical diameters, datums and mating interfaces.

C36000 Free-Machining Expertise

Review critical dimensions, datums and mating features and functional requirements before defining the process.

MAZAK Mill-Turn

Knurled brass parts, hex brass bodies, cross-drilled fittings, slotted adjusters, and compound valve bodies require the turning + C-axis milling combination that MAZAK mill-turn provides — producing all features from one datum without fixturing errors.

Complete Thread Capability

Thread cutting is the most quality-critical step for brass pipe fittings — NPT and BSP thread taper accuracy and pitch diameter govern the metal-to-metal interference that creates the hydraulic seal.

Knurl Precision

Consistent knurl quality requires matching knurl wheel tooth count to workpiece circumference — CNCPioneer calculates the target OD from knurl pitch for each new program so diamond and straight patterns track perfectly without "drunken knurl" double-tracking.

IATF 16949 Quality for Automotive OEM Brass Parts Supply

Brass CNC machined parts entering automotive supply chains — fuel system fittings, HVAC connector bodies, electrical terminal components, brake hydraulic fittings — require IATF 16949:2016 with PPAP Level 3.
