Reaching concentricity 0 using a simple collet chuck and this within one minute: this is Zero-Zero.
The specifically designed clamping nut with 6 symmetrically arranged screws at the circumference makes this step possible. The clamping nut is split, so that the inner ring can be minimally shifted. This simple technical finesse allows to eliminate tolerance additions.
The machine operator only has to replace the previous clamping nut, which step opens up a new concentricity dimension – and this for a price starting at € 90.00. Zero-Zero is available for DIN 6499 collet chuck holders from ER 16-ER40.
