Schunk brings Vero-S NSL quick-change clamping capability to mill-turns

The Vero-S NSL Turn achieves pull-down forces of up to 125 kN with holding forces of up to 375 kN by means of the patented double angled stroke and an integral turbo function. This ensures extremely rigid and reliable clamping of devices and workpieces, says Schunk. A centring taper ensures a run-out accuracy of less than 0.01 mm. Locking of the three or five integrated clamping modules is done via two clamping slides. The system is self-locking and uses form-fit clamping. During machining, the clamping station is unpressurised. Integrated springs provide permanent and secure clamping. For opening and locking, a pneumatic system with a pressure of 6 bar is sufficient. All functional parts such as the base body, clamping pin and clamping slide are made of hardened stainless steel. The maintenance-free modules are completely sealed and protected against chips, dust and coolant. A display shows the current clamping condition, and thus avoids errors before clamping. An intelligent plumbing of the module leaves enough space for bore holes on the base plate. Therefore the NSL clamping station can be used on all conventional machine types and is suitable for speeds of up to 2,000 rpm. In size 450, three clamping modules are available for 315 size manual chucks. Size 570 offers five clamping modules for manual chucks up to 630 mm.
