The patented SCHUNK chuck quick-change system ROTA FSW promises a fast chuck change in less than five minutes. Instead of using fastening screws and a drawbar adapter, the ROTA FSW is process-reliably loosened and locked with one single clamping screw. By a flexible adapter, the drawbar of the lathe is automatically connected with the rotary table, and is precisely centered by the patented flexible taper. A patented, extended and power jaw stroke ensure enormous pull-in forces, optimal location face, and an optimal rigidity of the connection. Locking is carried out form-fit and is self-locking. In order to exclude operating errors, a display continuously informs about the individual locking status.
The SCHUNK quick-change system can be retrofitted to almost every lathe. It is suitable for manual as well as power chucks. Their actuating force and maximum rotational speed remain fully preserved. Due to the low height, there are few restrictions in installation space. With its large through-hole, the SCHUNK ROTA FSW can be also used in modern turning centers. Already existing clamping devices can be adapted to the system with little effort and can be repeatedly used. The SCHUNK chuck quick-change system is available in three sizes for lathe chuck diameters 215 to 260 mm, 315 to 400 mm, and 400 to 630 mm.
