Its key role is to fix the workpiece and ensure that the workpiece will not move or become unstable during the machining process, thereby improving the machining quality and efficiency. These fixtures are not only compact and strong, but also flexible, easy to operate, safe and reliable. On the vertical machining center, the fixture not only clamps the workpiece, but also uses the positioning surfaces in all directions as reference datums to determine the zero point of the workpiece programming.

[0003] Publication number "CN219684653U" is a vertical machining center fixture, which relates to the field of fixture technology. The vertical machining center fixture includes a mounting box, a driving mechanism and a fixing mechanism. Two sets of movable slots are provided on the mounting box.
