02-20-2012 -
"The lathe chuck technology of the future." - this is what the sealed
3- or 6-jaw power chucks type ROTA NCS from SCHUNK are called by those who use them. The innovative lathe chuck from the competence leader in clamping technology and gripping systems combines high clamping forces, maximum precision and minimum effort. In view of the continuously increasing quality requirements in modern metal cutting, the benefits of the ROTA NCS ensure a maximum investment safety.
Hermetically sealed
The engineers from innovative family-owned company have done an excellent job during the development phases of these chucks. With its active jaw pull down, the ROTA NCS achieves top results in terms of face parallelism and perpendicularity. The achieved repeat accuracy achieves less than 0.01 mm! This is an outstanding lathe chuck for high-precision series production.
At the same time, the integrated permanent lubrication provides for a constant jaw clamping force, and therefore for a high efficiency level. Since the ROTA NCS is hermetically sealed against dirt and coolant, it is largely maintenance-free. All functional parts are hardened and ground, which ensures a long lifetime. Due to the low height, the chuck leaves plenty of room in the machining area.

Rings and castings can be also clamped gently and without deformation
In addition to the 3-jaw version, SCHUNK manufactures the ROTA NCS also as a high-precision 6-jaw chuck. During clamping of thin-walled and uneven components,
the 6 oscillating jaws ensure maximum run-out accuracy and minimum deformation at the workpieces. ROTA NCS 3-jaw power chucks are available in the standard sizes 175, 210, 250, 315, 400 and 500, and the 6-jaw version in sizes 250, 315, 400 und 500.
