The application of AM techniques has enabled WNT to create the high pressure chamber that operates the hydraulic chuck directly into the stem of the toolholder. This eliminates the previous requirement to braze the chamber in place, which was impossible to achieve accurately at small diameters.
The arrival of these hydraulic chucks brings productivity benefits to users. For instance, with a hydraulic chuck tool, set-up time is around a third of that when using shrink fit.
The WNT high pressure hydraulic chucks are available with SK40, BT40 and KSK-A 63 spindle taper fitments, which are able to accept tool shank diameters of 3, 4, 5, 6, 8, 10 and 12 mm.
