Overview of Brass Machined Parts
Brass Machined Parts are precision-engineered components produced through turning, milling, drilling, and threading operations on solid Brass rods or billets. These parts are known for their excellent machinability, dimensional stability, corrosion resistance, and aesthetic appeal. We manufacture a wide range of Brass Machined Parts including fittings, inserts, terminals, nuts, couplings, adapters, spacers, electrical pins, and hydraulic connectors.
Each component undergoes stringent dimensional inspection, thread gauging, and surface finishing to meet customer specifications. Typical machining operations are carried out on automatic bar feeders, sliding head CNC machines, and vertical milling centers. The production is supported by CAD/CAM-based programming and digital metrology.

Brass CNC Machined Components
Brass CNC Machined Components are produced on Computer Numerical Control (CNC) lathes and milling machines where precision and repeatability are paramount. These parts are ideal for complex geometries, fine threads, and multi-axis contours. CNC machining ensures tight tolerances, mirror-finish surfaces, and perfect concentricity — essential for aerospace, electrical, and hydraulic applications.
Our CNC capabilities include:
Multi-axis turning and milling (2–5 axes)
Micro-machining up to Ø 2 mm
High-speed spindle machining (up to 10,000 RPM)
Threading: BSP, BSPT, NPT, UNF, UNC, Metric, ISO
We deliver Brass CNC Machined Components such as valve bodies, instrumentation connectors, battery terminals, fluid fittings, and automotive sensors with tolerances up to ±0.01 mm and surface roughness (Ra) as low as 0.8 µm. All operations are performed under ISO 9001-certified quality systems.
Brass Precision Turned Components
Brass Precision Turned Components are manufactured on Swiss-type sliding head machines and automatic lathes. These components demand high dimensional accuracy and consistent concentricity. Applications include electrical connectors, PCB terminals, and instrumentation fittings.
Each turned component is verified through profile projectors, micrometers, and CMM inspections to ensure uniformity across batches. We support customer-supplied 2D/3D drawings (DWG, STEP, IGES) and can assist in value engineering for cost reduction.
Typical Dimensional Range:
| Parameter | Range |
|---|---|
| Diameter | Ø 2 mm – Ø 80 mm |
| Length | 3 mm – 250 mm |
| Tolerance | ± 0.01 mm |
| Surface Finish | Ra 0.8 µm – 1.6 µm |
Brass Screw Machine Parts
Brass Screw Machine Parts are produced using multi-spindle automatic lathes and turret lathes for large-volume, repetitive production. These parts are ideal for automotive, HVAC, and plumbing applications where cost-effectiveness and consistency are key.
Our screw machines can operate continuously with automatic bar feeders, producing tens of thousands of parts per shift. Each spindle performs a different operation (drilling, threading, facing, parting-off), ensuring cycle-time optimization and reduced cost per piece.
Advantages:
High productivity for mass production
Consistent dimensional control
Capability for cross-drilling, slotting, and tapping
