TER A perfect fit - with TER. With the developement of the patented TER shrink collet, we have been able to revolutionise the use of collets and collet chucks in the production process. Using TER means profiting from the three main advantages of collet shrinking, • Run-out < 3 µm • maximum holding forces • rigidity • low-wear monoblock properties without the need o replace existing collet chucks or spindles. The short and extremly stable tool clamping with TER achieves a run-out of < 3µm. Tool life considerably improved due to te precise guidance of the tool and ultra-precise change accuracy means that your length adjustement is maintained even after many cycles - with optimum results.
