Top 100: Smart Vice System Automates Stem Change

September 28, 2010

Grundodrill 4XThe 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).
