If you need cutting surfaces with minimum roughness and flatness, you can't do without the DE.130 turning unit. During the sawing process, the workpiece, which is held in a four-jaw chuck, rotates at the same time. The turning unit can be adjusted by hand in the X direction with an accuracy of 0.01 mm. A digital scale shows the current positions. Parts from 5 to 130 mm outside diameter can be clamped and separated with the turning unit. Even the smallest groove recesses can be produced with the DE.130. The unit is mounted on the grooving table. The speed is infinitely variable.
