Customized H62 Brass Roller Groove Cnc Milling Connector Spare Parts
These are high-precision, electrically conductive mechanical components designed for applications requiring reliable connections, manual adjustability, and secure assembly in electronic, mechanical, and fluid systems.
Electrical & RF Connectors: Custom waveguide flanges, coaxial connector bodies, banana plug jacks, and terminal blocks where brass provides excellent conductivity and shielding.
Precision Instruments: Micrometer thimbles, calibration dials, focusing rings for optical devices, and instrument adjustment knobs requiring a secure grip and fine control.
Fluid Power & Pneumatics: Brass fitting nuts, valve stems, compression fittings, and gauge connectors with slots for spanner wrenches or locking features.
Audio & Musical Equipment: Jack sleeves, input/output connectors, and potentiometer knobs benefiting from brass's conductivity, weight, and aesthetic.
General Mechanical Assembly: Custom bushings, spacers, coupling nuts, and alignment pins used in machinery where ease of machining and corrosion resistance are valued.
We specialize in the custom CNC machining of intricate connector components from H62 brass (CuZn38), incorporating specific functional features like knurling and slotting. H62 brass is selected for its superior free-machining characteristics, good electrical and thermal conductivity, and natural corrosion resistance. Using advanced CNC milling centers, we transform brass stock into complex parts with high dimensional accuracy. The knurling (diamond or straight pattern) is precisely applied to designated surfaces to provide an enhanced, non-slip grip for manual assembly or adjustment. The slotting (through slots, cross slots, or custom profiles) is machined to exact specifications, serving functions such as enabling wire access, accepting locking clips (e.g., E-rings), providing a drive surface for a tool, or reducing weight. These components are ideal for prototypes, low-to-medium volume production, or replacement parts where off-the-shelf solutions are unavailable.
| Category | Parameter | Details / Specification |
|---|---|---|
| Base Material | Material | H62 Brass (CuZn38) - UNS C28000 / CW508L |
| Composition | Approximately 60.5% Copper, 39.5% Zinc (Lead-Free). | |
| Key Properties | Excellent machinability, good strength & ductility, corrosion resistant, good electrical/thermal conductor. | |
| Component Features | Primary Function | Custom connector bodies, fittings, knobs, sleeves, and interface components. |
| Knurling | Type: Diamond pattern (standard), Straight pattern. Pitch (TPI): Customizable (e.g., 20, 25, 30 teeth per inch). Depth/Coarseness: Medium standard. Can be specified. | |
| Slotting | Type: Through slot, blind slot, cross slot, T-slot. Width: As per drawing, minimum practical ~ 0.8 mm. Purpose: For locking, wrenching, assembly, or wiring. | |
