Continuous waterjet cutting performance

Technology company ANT AG now offers a novel solution for a continuous suspension cutting processes using the ConSus abrasive mixing unit. With this technology, water abrasive suspension (WAS) can now also be used in the manufacturing industry. The suspension jet enables a more efficient cutting performance and a lower user load compared with conventional water abrasive injection systems (WAIS), reports the company.

In contrast to three-phase WAIS with water, abrasive and air, WAS systems work with a two-phase blasting tool. The cutting jet consists only of water and abrasive with a precisely adjustable flow rate. This suspension is created by the interaction of a main stream and a bypass stream.
Before the WAS arrives at the remotely handled cutting nozzle, it is put under high pressure. The high energy creates a cutting jet in the nozzle which exits at nearly twice the speed of sound. This efficiency is considerably higher than in the injection process, where turbulent mixing losses occur due to the contained air. In addition, due to the smaller nozzle diameter, the jet is more focused and cuts even the hardest materials precisely.
ANT’s ConSus (Continuous Suspension) system is operated at working pressures between 500 and 1500 bar. Compared with conventional waterjet cutting processes, the ANT suspension jet operates at less than half the pressure and, depending on the desired cutting performance, twice to three times the feed rate. The user receives thin kerfs without hardening or material deformation.
