Vargus releases Widia HydroForce HT universal hydraulic chuck

With a more compact and stable design, featuring a 40% thicker front wall cross-section, HydroForce HT, clamping force is up to three times better than regular hydraulic chucks, says Widia. Furthermore, with improved vibration dampening, run-out is 3 micron at 2xD overhang. Balance quality of G2.5 is achieved at speeds of up to 25,000 rpm. Widia says that only two sizes of HydroForce HT are required to suit all rotating tooling tasks: direct clamping is available for 20 and 32 mm diameters, with reducer sleeves applied for all other diameters. According to Widia, HydroForce HT is more cost effective than thermo shrink-fitting; offers up to four times more clamping force than collet chucks; and delivers higher balancing quality performance than power milling chucks.
