Bonded Disc Pack Flange Chucks LAFF Features • For clamping diameters from 7 mm to 80 mm • High true running accuracy ≤ 0,01 mm • Permissible component tolerance up to IT11 • Short or long clamping length possible • Pull-back against shoulder ring • For thin-walled or solid components • Impervious to ingress of foreign objects due to the rubberized slots in the Bonded Disc Pack Cap bush Seating body The Bonded Disc Pack Flange Chuck consists of a seating body, a cap bush, draw and cross bolts, base and shoulder rings, a Bonded Disc Pack, a thrust ring and a draw bush. The Bonded Disc Pack Flange Chuck is attached to the machine with the seating body. The Clamping Fixture is actuated via the draw bolt, which is connected to the machine power actuating unit. Depending on the required transmitted torque, Bonded Disc Packs of different widths may be installed. The required installation situations for the base and shoulder rings are shown in Fig. 9-2. Cross bolt Draw bolt Base ring Shoulder ring Bonded Disc Pack Thrust ring Draw bush Intermediate Flanges and Spring Force Actuators are shown starting on page 58. 8-2 Clamping principle The Bonded Disc Pack sits pre-loaded in the seating diameter of the seating body. To actuate clamping, the Bonded Disc Pack is raised to an upright position by axial actuating force. The component is centred, pressed flush against the shoulder ring and aligned. The tipping movement of the Bonded Disc Pack converts the axial actuating force into a radial clamping force that is up to ten times higher.
