This precision brass micro pin is engineered for applications where size and accuracy matter most. With diameters starting as small as 0.2 mm, these CNC turned pins are widely used in micro-connectors, electronic test probes, watch components, and precision sensors.
Each pin is manufactured on Swiss-type CNC lathes, capable of machining extremely fine shafts with consistent concentricity. The surface is polished and burr-free, ensuring smooth insertion into housings and stable performance even in high-cycle applications.
Why it stands out:
•Miniaturization without compromise – our brass micro pins combine strength and conductivity in an ultra-thin form factor.
•Superior tolerance control – available in ±0.005 mm, meeting the needs of high-frequency connectors and consumer electronics.
•Flexible finishing – choose from bare brass for cost efficiency, nickel plating for wear resistance, or gold plating for optimal conductivity.
•Trusted reliability – backed by ISO-certified process control, full inspection, and precision packaging that prevents bending or scratches during shipping.
Whether you need prototype runs for R&D or high-volume production for consumer electronics and IoT devices, these brass micro pins deliver the accuracy, stability, and quality that global buyers demand.

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).
