Description

Stainless steel precision turned micro pins are critical for miniaturized assemblies in industries like watchmaking, medical devices, and electronics. Our 304 stainless steel micro pins are produced via CNC turning to ensure ultra-high precision with ±0.01mm tolerance — perfect for applications demanding tight fits and reliable performance. With a polished surface for enhanced corrosion resistance and durability, these micro pins undergo 100% dimensional and visual inspection before shipment to guarantee quality. Whether you need standard sizes (such as diameter 0.5mm to 2mm with custom lengths) or fully customized precision micro pins, we offer a flexible MOQ of 50pcs, sample lead times of 3–5 working days, and bulk deliveries within 7–10 working days. Ideal for watch repair, medical instrument assembly, or electronic component manufacturing, our stainless steel precision turned micro pins deliver the precision and reliability your micro-engineered products require.

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.
