Cutting Glass with 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 7,200 PSI/500 bar to 11,600 PSI/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.

Advantages of Cutting Glass with Waterjet:

  • No Heat Affected Zones (HAZ)
  • Cut glass geometry that common machining cannot perform
  • No Hazardous Fumes or Vapors
  • No Material Hardening along cut edge
  • No Reworking, or minimal reworking
  • Precisely cut thin to thick glass without changing any tooling
Waterjet machining is a cold cutting process, making it ideal for automotive, medical and aerospace applications where the material cannot be affected by heat. Nearly every type of cut is possible, from using waterjet tables for rapid hole drilling to detailed cuts for most industrial applications.  Waterjet cutters use an abrasive additive to create a clean, burr-free cut that does not require secondary finishing – saving both time and money.
