📘 Water jet processing techniques based on the use of fluid flow as a carrier or a conductor of high energy, currently being actively developed. In this book we have tried to show that blasting is a promising technology to obtain the various surfaces in products of modern materials, including high-strength and super hard materials. In combination with other energy sources, primarily the laser beam, with the liquid jet successfully handles heavy duty synthetic materials used in the tool making. In the long term - the use of this method for manufacturing sandblasting precision products made of composite materials.
