Secure demanding workpieces with extreme clamping force and zero vibration using industrial-grade NC High-Pressure Vices (mechanical-hydraulic CNC machine vices / high-pressure power vices). Designed for heavy-duty milling, drilling, and multi-axis CNC machining, these precision vices incorporate a mechanical-hydraulic power intensifier spindle that multiplies manual input torque into massive clamping forces (up to 40 kN or higher). Built with a rigid ductile iron or steel base, hardened and ground guideways, and precision-aligned step jaws, they ensure rigid workpiece retention, eliminate jaw lift, and maintain repeatable accuracy across production runs.
