Simple, practical, good EROWA’s ITS chuck operates on a principle that is as simple as it is ingenious. It holds both tools and workpieces with equal precision and with a high degree of repeatability. Its applications are so numerous that it forms the basis for a well thought-out modular tooling system.
• Tens of thousands of ITS chucks are in daily operation worldwide - with their guaranteed 2-µm accuracy and with a reliability they have earned for themselves in practical working application.
• Integrated on milling, grinding and drilling machines, on EDM sinking and WEDM centers or on measuring and presetting stations, ITS helps us week after week to achieve a profitable use of production time.

The two pictures illustrate the ITS patent. After a rough pre-centering process, the reference position is only reached when the centering plate is flexed. Together with the contact points, this flexing action creates the stability of the frictional connection. This is how positioning accuracy is created between the flexible centering plate and the rigid centering prisms.

ITS The Original. Nothing is copied as fast as a pioneering invention. But then a copy always lags behind the times. It won’t be different with the next innovative idea. We will ensure that you continue to do well if you invest your money in originals. In originals by EROWA.
