This is our ultra-fine pin that is thinner than a mechanical pencil lead.

At Takano Co., Ltd., we leverage our precision machining expertise cultivated in mold components to achieve ultra-precise grinding of pins with diameters below φ1.0mm.
Though nearly invisible to the naked eye, these delicate parts meet the demanding requirements of precision machinery and medical applications with exceptional accuracy and finish.

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

We serve a wide range of industries including precision molds, medical devices, semiconductor equipment, and factory automation (FA).
