TORG ENGINEERING uses an abrasive water jet (AWJ) to cut stone. The process involves critical control of initial cutting pressure otherwise frangible materials like stone will shatter at the beginning of a cut. Once the cut path is established the cutting pressure can be raised to the normal operating amount of 60,000psi. Cutting stone is part science and part art because no two pieces are exactly the same. With this in mind we like to have samples that we can fine tune our set up prior to cutting your valuable stone.
