Abrasive waterjet 6,200 bar: abrasive waterjet cutting speeds by thickness
The values below come from the KMT Waterjet Products & Services brochure 2024-10 (possible cutting speeds, medium–smooth): the lower end of the published range for a medium to smooth cut, per orifice size and abrasive rate. Mild steel is STM's cost example at the same pressure and orifice.
These are the maker's figures for a new, well-set machine at its recommended settings. Your machine may cut slower with worn consumables, or faster when the edge allows it. A starting point, not a quote.
In Nest&Quote a machine's speed table is filled from this chart in one click, each row with its source, for you to check and correct. The cut time and the price then come from your own rows, and real run times adjust the rest.
