BiSON Combination four-jaw lathe chuck - with individual and centric jaw adjustment Standard DIN 6351 Wescott system. Material Cast iron Application Combined clamping option due to two different jaw adjustments a) Self-centring adjustment of the base jaws (geared scroll); b) Individual adjustment of top jaws. This allows irregularly shaped components to be clamped as if to a face plate. The gear scroll for jaw adjustment is through-hardened, the flanks of the scroll and of the bottom jaw teeth are ground on both sides. 31 5635- With recessed mount DIN 6351 Form A. The chuck is mounted on a flange by screws inserted from the rear and the flange is then mounted on the lathe spindle. Flange blanks (see No. 317000) must first be adapted to the machine and then to the lathe chuck. 31 5645- With short taper arbor DIN 55027 with studs and collar nuts for spindle noses to DIN 55027 (DIN 55027 and international standard ISO 702/111 are identical to DIN 55022 (old standard)).
