spindle interface ISO 26623 HAIMER PSC tool holders

The ISO 26623 spindle interface is an innovative tooling system with maximum precision and particularly widespread in multi-task machines (turn-mill centres). The torque transmission and centering takes place via the polygon-shaped taper with flange surface contact. As a result, a fixed axial positioning and a high degree of torsional rigidity is achieved.
