Same’s waterjet cutting machine is developed by Guangzhou Sino Achieve Mechanical Equipment Co., Ltd. (foreign investment venture).SAME is a sophisticated high-tech enterprise and a member of Guangdong Province Stone Association and Technical Commission of Standard Jet Equipment of National Mechanism Bureau. It has acquired many technical improvement prizes in province and city. The waterjet cutting machine is a high-tech product in corporates the strong points of mechanics, computer and automatic control. The wterjet cutting system has many advantages: never changing the internal structure of the material, no selection of cutting material, high quality of the kerf, material-saving and high intelligence. Therefore, it can be widely applied in the range of metal, nonmetal, composites plate cutting and the machining of ceramic and glasses and stone. Same’s waterjet cutting system makes great improvement in working condition. There cause no dust, no odor, no poison and llitle vibration while cutting. In this method, the cutting surface is rather smooth. Because waterjets cut with a narrow kerf, so raw material usage is maximized. It reaches the international advanced level of 1990’s after the appraisal of experts. In addition, the waterjet cutting machine achieved the practical and new type patent certificate of China in 1997. (Patent No: ZL 97 245724.0), and it has been show in Xinghuo Technology of CCTV as a high-tech technology project of Guangdong Province.
