Jet Edge Inc. (St. Michael, Minn.) has introduced its new Mid Rail Gantry waterjet system. It features an 8-by-13-ft (2.4-by-3.9m) work envelope with an exposed tank that accommodates overhead loading. It comes standard with one abrasivejet cutting head; a second cutting head can be added to increase productivity. The Mid Rail Gantry is ball-screw-driven for higher accuracy. Its heavy-wall tubular steel construction reportedly eliminates vibration and increases longevity. The machine uses an industrial PC controller and can be configured so that all three axes are fully programmable (Z optional). It also features direct-couple AC brushless digital servo motors and single or double carriages. Critical bearing components are protected with heavy metal covers with brush seals.
