Cutting Glass Systems | Powered by KMT Waterjet
Abrasive waterjet cutting technology is a great method for cutting glass because it allows for contours and shapes that cannot be achieved with other cutting machines at a reasonable cost. From artistic tabletop inlays to detailed stained glass designs, mirrors, glass ornaments, replacement windows for antique cars, and more, there’s almost no glass cutting application* that a waterjet cutting machine from KMT Waterjet can’t tackle. *(Not suitable for the processing of tempered or hot glass)
Glass has a tendency to crack, so it is very important that the initial holes are produced with a reduced pressure of 500 bar to 800 bar. Subsequently, the pressure must be increased to a cutting speed that is cost-effective. For glass, ceramics and other brittle materials, you must gradually increase and reduce the cutting pressure by means of proportional pressure control of the intensifier pump, otherwise the material would be destroyed.
As an alternative to quartz sand, olivine can be used as an abrasive because it is softer, which reduces the potential for chipping, cracking and other surface blemishes and leaves a cut edge that is polished to a smooth finish.
Because water jet cutting does not vibrate the glass, there is no heat-affected zones (HAZ), or leave behind rough edges, almost no secondary finishing is required.
