This pipe is used for copper electrodes.

Our company’s electrode pipes are available with both large diameter and high precision. No other company can provide this degree of precision at such diameters.
Since electroforming makes for stable dimensions, secondary processing such as cutting is not required. This is useful in terms of pricing.
Our cost-reduction efforts aimed at large companies have been well received.
Use these for R groove processing, through holes for electrodes, and processing of fine grooves (or ultra-fine grooves).
