Garnet offers a choice of grades to match any focusing tube and orifice for any given cutting application. Garnet 80 Mesh: The most popular waterjet cutting abrasive grade used worldwide delivers the optimum balance of cutting speed and precision edge. Garnet 50 or 60 Mesh: Suitable for high speed waterjet cutting, it can in some cases deliver up to a 30% increase in cutting speed but at the expense of a reduced precision edge. Garnet 120 Mesh: For high precision and minimum tolerance edge waterjet cutting requirements. The table states the correct combinations of Garnet grades, focusing tube and orifice dimensions to suit your particular waterjet cutting requirements. |
