Tungaloy’s New Collet Chuck Sleeve Strengthens ID Turning Capability for Small Diameters

Iwaki, July 2019 — Tungaloy introduces a new line of collet chuck sleeves for the TinyMini-Turn miniature boring tool system, enabling a quick changeover of its solid carbide boring bars.

TinyMini-Turn is a boring tool system consisting of solid carbide boring bars and sleeves, designed for high precision internal boring, grooving, and threading applications in extremely small diameters as small as 0.6 mm (.024″).

This new sleeve features an integrated collect chuck for precision clamping and repeatability as well as quick changeover of boring bars while the sleeve remains mounted in the tool post. A boring bar can easily be changed by operating the clamping cap equipped on the sleeve. In addition, the collet chuck provides full contact gripping on the boring bar shank for higher stability and repeatability over conventional bolt-clamp holders. The sleeve is capable of through-coolant supply for improved chip evacuation and tool life.
