Ceramic spin gauges have advantages that are not found in carbide or steel. This is a page explaining the advantages of ceramic spin gauges.

In recent years, with the increasing precision of components, pin gauges themselves are also required to be highly precise. Our company manufactures pin gauges with an outer diameter tolerance of ±0.1μm (±0.0001mm). They can be used for master pin gauges for measuring instrument calibration and other pins that require high precision in outer diameter tolerances. Please take a look at our product page.

This is a stack pin (positioning pin) that is driven in when fixing the entry board and backup board (bake board) before drilling the substrate.

Precision: φ±0.005 (higher precision tolerances are also possible), outer diameter surface roughness can be less than Ra0.1. Material: SKH51 (HRC60 or higher), SUS materials, carbide, etc. We can manufacture from small lots, so please feel free to consult with us.
