Description

This precision brass test probe pin is engineered through Swiss CNC turning technology, achieving high accuracy with ±0.01mm tolerance. Made from durable brass (C3604 / CuZn39Pb3), it provides excellent conductivity, corrosion resistance, and wear resistance, ensuring reliable performance in demanding applications.

With its slender and finely machined design, the pin is widely used for test probes, electronic connectors, sockets, semiconductor devices, PCB testing, and precision instrumentation. Surface finishing options include gold plating for enhanced conductivity, nickel plating for durability, and tin plating for solderability, making it suitable for multiple industries such as electronics, telecommunications, medical devices, and aerospace.

Our facility supports OEM/ODM customization, delivering flexible solutions to meet unique client requirements. With fast sampling (5–7 days), consistent mass production (2–3 weeks), and strict QC inspections, this component ensures high-quality and reliable supply for global buyers.

Our CNC Machining Facilities & Capabilities

At JXD Machining, we operate a 5,000+ square meter fully integrated CNC machining facility, armed with a fleet of 40+ advanced pieces of equipment to meet diverse customization demands. Our core equipment lineup includes: 12 sets of 3-axis CNC milling centers (Haas VF-2), 8 sets of 4-axis machining centers (DMG MORI CMX 1100 V), 5 sets of high-precision 5-axis milling centers (MAZAK Variaxis i-700), 10 sets of CNC turning lathes (Okuma LT2000-MY), 3 sets of Swiss-type automatic lathes (Citizen M32), and a complete Surface Treatment line covering anodizing, sandblasting, and powder coating.

 

We excel in both flexible rapid prototyping and stable high-volume production: we support 1-50 pieces of rapid sampling and 10,000+ pieces of mass production, with the ability to process over 20 Materials including Aluminum(6061/7075), Stainless Steel(304/316), Titanium alloy (TC4), Brass, and engineering Plastics ( POM  / PEEK ). With a strict tolerance control range of ±0.005mm to ±0.05mm, we easily handle complex structures such as deep holes, curved surfaces, and multi-step components, serving key industries like Electronics, Medical devices, Consumer Products, and Industrial Automation.

On delivery efficiency, we balance speed and precision: rapid prototyping takes 3-5 working days, small-batch production (50-500 pieces) is completed in 7-10 working days, and large-volume orders are delivered within 15-25 working days (adjustable based on order scale and complexity).

Quality Assurance

At JXD Machining, our strict, streamlined quality & outbound process—backed by advanced tools—guarantees compliance:

Incoming Check: Verify raw material certificates + sample tests (hardness, composition) to rule out defects.

In-Process Inspection: Spot-check critical stages with CMMs to validate tolerances (±0.001mm) early.

100% Final Test: Full dimensional, surface roughness, and functional checks—only passers move forward.

Outbound Review: Secure packaging + batch labeling; test reports/certifications included for traceability.
