Hilma NC-series vises are ideal for precision, high-production machining on vertical machining centers. Fixed and sliding jaws are precision ground to accept top-jaw tooling. Finest-quality construction for excellent rigidity and durability. The hydraulic version provides automatic power clamping with exact force at the push of a button (requires external power unit). Made in Germany.
Maximum clamping force at 5000 psi is 11000 lbs.
During initial setup, move the sliding jaw into approximate position by moving the hardened steel cross-pin into a different hole in the base. Next, adjust jaw opening to the workpiece using the removable crank handle. When fluid pressure is applied by actuating the external power unit, the sliding jaw moves through its power stroke (.276" maximum stroke for safety) to apply full clamping force. Unclamping is by positive spring return.
Vises are all slotted for 20mm fixture keys, to provide accurate mounting on T-slotted machine tables. Use two Step Fixture Keys to adapt to a specific table-slot size. Fasten with Vise Clamps holding the bottom ledge.
Vise bed is flame hardened and ground to a +/-0.0004" height dimension. Fixed and sliding jaws are ground to a +/-0.0008" height dimension to accept top-jaw tooling. Fixed-jaw location is +/-0.0016" from the fixture-key slots.
A crank handle is furnished with each vise.
