Toolholder with ER collet chuck and quick change system combines unique benefits

Dimac introduces to the market the new WTO QuickFlex quick change system for turning and milling applications. QuickFlex combines an ER collet chuck and a quick change system in one toolholder. The systems come as a straight drill/milling unit and a right angle drill/milling unit, which makes them ideal for lathes with milling capability.

“As a toolholder with ER collet chuck and quick change capability this system combines unique benefits,” explains Dimac Director Paul Fowler. “The unique advantage of QuickFlex starts with a minimal investment. The customer can clamp the cutting tools directly in the toolholder using a standard ER collet. That means you can start with a basic system at a small investment and later you buy quick change adapters when you would like to add the quick change function.”

Another advantage is that the cutting tools can be pre-set while the machine is operating. Moreover, the time for tool changes is significantly reduced with the new and one-hand wrench (patent pending).

Integral part of the QuickFlex system are two independent taper connections. The short taper, which is positioned just behind the thread for the QuickFlex adapter, provides radial centering and axial support of the adapter. Moreover, it protects the toolholder from chips and dirt. The radial bearing support for the adapter further back ensures high stiffness under load. As a result, permanent accuracy of the run-out is assured.

The new one-hand wrench makes tool changes easy and quick. The wrench can be used to change ER collet nuts as well as the QuickFlex adapters and eliminates the cumbersome and ineffective clamping and releasing of nuts used in other toolchange systems.

WTO introduced the QuickFlex toolholder during EMO 2011. The system is available as a starter set in a carrying case, including three quick change adaptors (Weldon/Whistle-Notch adaptor, short combination mill adaptor and a collet chuck), two spanner wrenches and the one-hand wrench. In 2012 the QuickFlex program will cover well-established machines with bolt-on tooling-type turrets.
