DeltaIV-750: 101 x 228mm (4 x 9")
Other lengths available
Improving on traditional self-centring vices, Delta IV is a family of "fixed-centring" multi-axis vices that decouples locating and clamping. Jaw location on the 1st and 2nd axes is provided by serrations on a hardened steel base and matching serrations on a fixed jaw. Clamping force is provided with a fast-acting, high strength steel screw.
The heart of the vice is the patent-pending Delta jaw-retention system, which provides pull-down force and locating on the 3rd axis.
The net result is significantly better rigidity and accuracy - especially well suited for secondary operations, often neglected with self-centring vices.
