Dormer Pramet has launched a high precision, quick-change tooling system for a variety of internal and external turning applications.
Ideal for use on multi-task machines, the polygon shank coupling (PSC) is a spindle interface which promotes higher productivity through reduced set-up time and faster, more precise machining.
It achieves this with a unique tapered polygon cone shank and flange surface, which supports a high degree of rigidity. With an accuracy in X, Y, Z directions of +/-2 μm, the PSC holders provide a high level of repeatability.
In addition, a reduced overhang length minimises vibration and runout inaccuracy for a high-quality surface finish, making it ideal for aerospace and general machining applications.
Connected by a triangular conical structure and cross section, which uses 1/20 taper, the PSC features internal coolant channels and a steel toolholder for high toughness.
More than 130 different items are available, including a variety of tool holder styles, internal tools, interface types and shank sizes.
