USED HILMA SM-125

Hilma Type SM-125 Heavy-Duty Hydraulic Machinist ViseManufacturer: Roemheld-Hilma (Germany) | Jaw Width: 5" (125mm) | Force: 7,700 lbsExecutive SummaryThe Hilma SM-125 is a premium, German-engineered mechanical-hydraulic vise designed for high-precision production and heavy-duty toolroom applications. Renowned for its massive clamping force and "tenths" repeatability, this vise utilizes a self-contained hydraulic power intensifier that allows for incredible holding power with minimal manual effort. Unlike standard mechanical vises, the SM-125 ensures consistent, vibration-free clamping, making it ideal for aggressive milling on CNC vertical and horizontal machining centers.Technical SpecificationsJaw Width: 5.00" (125 mm)Max Clamping Force: 7,700 lbs (40 kN) – achieved with minimal handle torqueClamping Range: 0 – 8.85" (225 mm) standard; expandable with step jawsRepeatability: 0.01 mm (0.0004") for high-precision batch productionOperation: Mechanical-hydraulic (no external pump or hoses required)Base Type: Heavy-duty fixed base with hardened and ground steel guidewaysKey Performance FeaturesInternal Hydraulic Intensifier: Features a "power assist" system where the first stage is mechanical for fast positioning, and the second stage automatically engages a hydraulic piston to apply full high-pressure clamping.Industrial Durability: The vise body is constructed from high-quality steel (not cast iron), featuring flame-hardened and ground ways that resist wear and maintain accuracy over decades of use.Versatile Workholding: The fixed and sliding jaws are ground to accept a wide variety of Hilma top-tooling, including stepped jaws, prismatic jaws for rounds, and soft jaws for complex geometries.Chip & Coolant Protection: The lead screw and hydraulic transmission are fully encapsulated within the carriage, preventing swarf from fouling the mechanism and reducing maintenance downtime.
