Small CNC Machined Parts Manufacturer for Precision Applications

Small CNC Machined Parts Manufacturer for Precision Applications

In industries where size matters — and precision matters even more — small CNC machined parts play a vital role. From tiny aerospace fittings to medical device components and electronics housings, these parts must meet strict tolerances, surface quality, and functional integrity.

At HKAA, we specialize in CNC machining of small parts using 3-, 4-, and 5-axis equipment, producing components as small as 3mm in diameter with micron-level accuracy. Whether for prototypes or high-volume production, we ensure every part performs flawlessly in its final application.

✅ Case Study: Micro Brass Contact Pin for Electronic Device

In 2024, a UK-based electronics company commissioned HKAA to manufacture brass contact pins for a medical diagnostic sensor.

Project Highlights:

• Size: Ø2.2mm x 11.5mm

• Material: Brass C3604

• Tolerance: ±0.006mm

• Surface: Passivated + deburred edges

• Quantity: 50,000 pcs/month

• Function: Electrical conduction + press-fit assembly

We used 5-axis micro turning and polishing processes. All pins passed current flow and insertion force testing. Client feedback: 100% acceptance rate and zero quality complaints over six months.
