One of the main functions of a vise is to firmly fix the workpiece. In the machining process of a machining center, it is necessary to ensure that the workpiece remains stable during high-speed cutting, milling, drilling and other operations. through strong clamping force, the vise can tightly fix workpieces of different shapes and sizes on the workbench to prevent the workpiece from displacing, shaking or rotating during the machining process, thus ensuring machining accuracy and quality.
