Abstract
A precision machine vise is provided with quick-change head members or means to facilitate the changeover from making one kind of part to another, preferably in equipment provided with computer numerical control. The precision machine vise is of the kind having obliquely oriented surfaces as an anti-cocking measure. One first part of the equipment supported by the base of the precision machine vise has an upstanding boss, and a second part of the equipment containing jaw plates in contact with the work has a vertical bore in which said boss fits, and there is a horizontal bore through the boss of the first part and through the second part, into and through which a locking-in means fits. The first part is provided with means to minimize play between the first part and the second. The second part mentioned above may be a disposable item. For use with a precision machine vise of the two-place type, there is also provided a changeable 'fixed' central member, securable to the base via bolts accessible from above.
