FIELD: instrument making.SUBSTANCE: mandrel is intended for hemispherical charges installation on the jacks and includes a case with a shank. To increase the processing accuracy and the possibility of charges installation with difference in sizes of inner surfaces of up to 3 mM It is equipped with a centering bushing, with the possibility to move along the case shank perpendicular to its axis under pressure spring, which clamps adaptor to the inner surface of a charge, and charge centering relatively to mandrel axis.EFFECT: increased processing accuracy.1 cl, 1 dwg
