A milling fixture in the form of a spiral lathe chuck with split jaws, integrated with the base. Depending on the adaptation, it can be used on milling machine tables, T-towers, drill tables, surface grinders. Its low-profile design maximizes Z-axis working range, while the sealed construction protects the mechanism from chips and contaminants. The wide clamping range and long jaw travel allow secure clamping of workpieces in various sizes without the need to change or maintain multiple jaw sets.
