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

Our capabilities include producing long, micro-diameter metal pins (under Ø1.0 mm) with high accuracy, featuring tip SR (spherical radius) finishing, multi-step taper geometries, and precision grinding.

In particular, we offer solutions using SUS440C stainless steel, known for its high hardness, excellent wear resistance, and corrosion resistance, making it ideal for medical devices and precision applications.

We support high-mix, low-volume production and custom specifications for industries such as medical devices, semiconductor equipment, precision molds, and factory automation (FA).

Our products are widely used as medical mandrels, core pins, guide pins, and micro shafts, contributing to miniaturization and high-performance engineering.
