The QuickFlex system includes two independent taper connections. The short taper (8), located closely behind the thread of the collet chuck, is for radial centering and axial support of the QuickFlex adapter. This taper contributes to the precision of the system, independent of possible abrasion at the cone of the ER collet chuck. The location of the taper behind the thread (7) keeps it protected against chips and dirt for long-term continued precision. The short taper also works as a defned contact face, whereas the rear part of the ER collet chuck cone guarantees backlash-free radial bending support of the QuickFlex adapter (11). Combined with the large thread (7), these two taper connections lead to the high rigidity and stability of the system. Additionally, the full performance can be transmitted from the turning center to the cutting tools. The polygonal torque transmission (10) is placed just behind the radial support.

Adapters (which use the built-in thread nut) are tightened the same way. Te system is also designed for fexibility. While the toolholder can be used without a quick- change system, a quick- change function can be easily added. Adding quick-change adapters after the initial purchase can reduce tool change time even more dramati- cally. Te complete quick starter kit includes three diferent adapters and a one-hand wrench set. In the past, changing tools has been difcult, time consuming, and in some cases, risky. Te QuickFlex system is designed to address these issues. "With QuickFlex, our goal was to develop a compact, simple and safe quick-change system for driven toolholders," says Karlheinz Jansen, technical director and member of management, WTO GmbH.
