We specialize in manufacturing ultra-fine diameter pins and micro precision shafts using advanced grinding technology.

This product features SUS316 stainless steel, offering excellent corrosion resistance and suitability for medical, cleanroom, and high-reliability environments.

In addition, we achieve an ultra-smooth surface roughness of Ra 0.0033, ensuring superior performance in applications requiring high precision, low friction, and stable positioning.

Our capabilities include producing long, micro-diameter pins (sub-millimeter range) with advanced features such as tip SR (radius) finishing and multi-step taper geometries, supporting high-mix, low-volume production.
