Top 100: Smart Vice System Automates Stem Change

Sept. 28, 2010

The Computerized Smart Vice system on TT Technologies' Grundodrill 4X simplifies drilling by cycling the vice automatically. The vice is self-centering, but its single push-button control can be overridden with a switch that gives the operator manual vice control for special situations. The unit puts 9,200 pounds of thrust and pullback into a footprint that's less than 11 feet long by 3 feet wide. Hydrostatic drive develops 950 foot-pounds of torque and spindle speeds up to 230 rpm. Estimated price: $85,000 (incl. external bentonite system/trailer).
