Using a high-pressure washing machine to clean stone can remove dirt and adjust water parameters for further material processing. It can be used to treat the surfaces of marble, stone, and concrete with varying hardness and texture. The high-pressure water jet principle can be used for cleaning, crushing, roughening, and deburring purposes. In addition to its cleaning function, high-pressure water technology can also achieve a "water-washed" surface effect by directly impacting the softer glass components of the stone surface to create a decorative rough surface effect.

High-pressure water jet can also be used to polish stone, making the surface smooth and highly polished to achieve a mirror-like effect, giving it a glossy finish. The general glossiness of stone can reach 80 to 90 degrees, and some types of stone can even reach over 100 degrees. Polishing is achieved by using a resin disc to polish the surface, which can fully display the natural texture and color of the stone.

High-pressure water can also be used to roughen the surface of stone, increasing its friction and adhesion. Roughening is mainly applied to the surface of walls for tile installation. Since tiles cannot be firmly attached to smooth surfaces, it is necessary to roughen the wall surface to achieve a rough surface effect. This method is widely used in the construction industry, cement factories, and building materials industry.

The advantage of high-pressure water surface treatment is that it does not generate heat, which solves the problem of deformation and surface hardening of stone. One of the most common forms of precision processing of hard stones containing quartz is through thermal treatment. However, not every stone is suitable for thermal treatment, and color changes may occur depending on the material. Yellow granite may turn red, while others may turn yellow or gray. In order to achieve surface texture processing without changing the color, a high-pressure water system can be used to treat stones that are prone to color changes with water jets. The results are unparalleled by traditional processing techniques.

Using a high-pressure cleaning machine with added abrasive or high-hardness fine sand, the water jet cutting technology can be carried out at high speed to erode the stone workpiece, and then cut many different materials. The cutting surface is smooth and almost free of burrs, and there is no need for secondary processing. There is also no dust or toxic gas generated during cutting. When combined with CNC machine tool control, high precision cutting can be achieved, and the most suitable cutting process can be selected depending on the design and material of the workpiece, greatly improving productivity.
