I. INTRODUCTION With the rapid development of modern science and technology, the machine tool industry is faced with the requirements of high-precision, high-speed, high efficiency and diversified materials to be cut, and the requirements for the quality of parts processing are also getting higher and higher. In order to meet these requirements, Must improve the machine’s static and dynamic performance. One way to do this is to use structural materials with good properties. Polymerized mineral composite (PMC) is a new?
