The TACH-JET water jet system cuts parts up to 6” thick from virtually any material. It is available in two sizes: 40” x 40” (1000 mm x 1000 mm) and 60” x 60” (1500 mm x 1500 mm). It can be configured for both abrasive water jet cutting and water-only cutting (abrasive is added when cutting hard materials such as metals; soft materials such as foam can typically be cut with water only). It requires a 120 V 60 Hz power source, fresh water source and a suitable tractor or skid steer (supplied by customer). Tractor or skid steer must have a hydraulic power unit capable of a minimum output of 50 HP (must be capable of supplying continuous 2400 psi fluid at 21 gpm ).
