Techni Waterjet’s Quantum ESP66 electric servo pump features a servo motor that directly envelopes a high-load, precision ballscrew. The ballscrew directly houses ceramic plungers that reciprocate back and forth to create the pumping action, in much the same way as a hydraulic cylinder works on an intensifier pump, the company says.
The Techjet-X2 line of waterjet machines, which use linear scale feedback to ensure high accuracy of motion, is also on display. By mapping the entire cutting area with a laser-calibrated digital encoder, the motion system can deliver positional accuracy of 0.0005" (0.01 mm) and cutting speeds ranging to 1,000 ipm or 25 m/min.
The company’s abrasive delivery pump and hopper system feature an abrasive pump in which no mechanical moving parts come into contact with the abrasive material (garnet). This ensures consistent abrasive flow to the cutting head for many hours with virtually no maintenance, the company says.
