Brass Precision Turned Components Manufacturer
CNC precision turned brass components manufactured to drawing in Jamnagar, India. Free cutting brass (IS 319 / CW614N), tight tolerances, threading, knurling, and plating. ISO 9001:2015.
Pixon Metals manufactures precision turned brass components for OEM, industrial, and export buyers from our Jamnagar, Gujarat facility. Precision turning produces cylindrical or near-cylindrical components — connectors, adaptors, bushes, nipples, stems, spacers, and threaded fittings — by removing material from brass rod stock on CNC or multi-spindle lathes.
Our turning operations cover a wide range of component geometries, from simple spacers and standoffs to multi-step parts with threads, knurling, cross-drillings, and machined profiles — all produced against customer-supplied drawings.
Brass Grades Used in Precision Turning
The material grade affects machinability, surface finish, thread quality, and corrosion behaviour. Our standard options for turned components:
| Grade | Standard | Composition (approx.) | Best For |
|---|---|---|---|
| Free Cutting Brass | IS 319 / CW614N (EN 12164) | 58% Cu, 39% Zn, 3% Pb | High-volume CNC turning, fine threads, excellent surface finish |
| Lead-Free Brass | CW510L / IS 319 Pb-free | 63% Cu, 37% Zn, <0.1% Pb | Drinking water, RoHS-critical applications |
| Naval Brass | CW712R / IS 291 Grade 2 | 59% Cu, 40% Zn, 0.75% Sn | Marine, corrosion-resistant turning |
| DZR Brass | CW602N | 62% Cu, 36% Zn, 2% Pb, As | Plumbing fittings, dezincification risk environments |
Free cutting brass (IS 319) is the standard material for most precision CNC turning in Jamnagar due to its excellent machinability, clean chip formation, and suitability for high-speed turning and threading.
Tolerances and Machining Capabilities
- Turned diameter tolerances: typically ±0.05 mm for general components; ±0.01 mm achievable for close-tolerance fits on request
- Length tolerances: ±0.1 mm standard; tighter on request
- Thread cutting: Metric ISO 68-1, BSP ISO 7/1, NPT ASME B1.20.1, and custom profiles
- Knurling: straight, diamond, and cross knurl patterns
- Cross-drilling, slotting, and milling in the same operation
- Component size range: typically 2 mm to 150 mm diameter, up to 500 mm length (varies by geometry)
Surface Finishes for Turned Components
- Natural brass — polished or deburred, no plating
- Nickel plating — 5–20 μm electrodeposited nickel; improved hardness and corrosion resistance
- Tin plating — 5–15 μm electrodeposited tin; excellent solderability, RoHS compliant
- Zinc plating — for mild steel components in the same order
- Chromate conversion — for aluminium components
- Custom finishes available on request

How to Get a Quote for Precision Turned Components
The fastest way to receive an accurate quotation is to share a dimensioned drawing with material callout, required finish, and quantity. We accept PDF, DXF, and STEP files. Indicate whether threads need gauging, whether a first article inspection report is required, and your target delivery date.
Frequently Asked Questions
What tolerances can you achieve on precision turned brass components?
Standard CNC turning achieves ±0.05 mm on diameters and ±0.1 mm on lengths. For close-tolerance fits such as bearing seats or press fits, we can hold ±0.01 mm on diameter with appropriate process controls. Specify your tolerance requirements on the drawing.
What is free cutting brass and why is it used for precision turning?
Free cutting brass (IS 319 in India, CW614N under EN 12164 in Europe) contains approximately 3% lead, which acts as a chip-breaker during machining. This gives it superior machinability — faster cutting speeds, better surface finish, and longer tool life — compared to lead-free alloys. It is the standard alloy for CNC turning in Jamnagar and globally.
Can you machine threads during the turning process?
Yes. We cut internal and external threads as part of the CNC turning operation. Standard thread forms include Metric (ISO 68-1), BSP (ISO 7/1 and ISO 228-1), NPT (ASME B1.20.1), and UNC/UNF. Thread gauging (Go/No-Go) is available on request.
What is the typical lead time for precision turned brass components?
Lead time depends on complexity and quantity. Simple components in standard brass can typically be produced in 2–4 weeks from drawing approval. Complex parts with multiple operations may take 4–6 weeks. Prototype quantities are often faster.
