The development of communication technology has led to the development of computers and consumer electronics. In recent years, following the development of the digital age, with the mobile phone and telecommunications industry as the main axis, 3C products such as mobile phones, wireless communication equipment, transmission equipment, notebook computers, various computer hardware and peripheral equipment have gradually developed into a worldwide one. The emerging technology industry is currently the fastest growing industry. 3C products are available in a variety of styles. In addition to the internal circuit board and screen, most of the parts, including the outer casing and internal parts, mainly include plastic and sheet metal parts. Plastic products such as mobile phones, mice, and digital camera casings have different shapes. Considering the aesthetics and practicability of the design, they are mostly complex curved surfaces. The technical difficulty is concentrated on the processing of complex curved surfaces. Accuracy and automation have higher requirements. For this type of part, it is usually injection molded and then machined into the parts we need. Three-dimensional modeling and parting with UG, Pro/E and other three-dimensional software are used to generate CNC machining programs with CAM programming functions, and finally the machining of molds and their parts is completed on CNC machine tools. Sheet metal parts such as computer cases, exchange equipment, transmission equipment and other shells and internal parts of some electronic consumer products, such parts are large in volume, long production cycle, stamping and forming with molds. For the shape characteristics of these two types of parts, the most suitable machine for machining these two types of parts is the vertical machining center. All of these machines, especially CNC high-speed machine tools, have been monopolized by foreign machine tool manufacturers. It is imperative for domestic machine tool manufacturers to change the manufacturing of 3C products. Hanchuan Machine Tool is a key large-scale backbone enterprise integrating product research and development, design, manufacture, sales and service in China's machine tool industry. It is an important production base of national precision CNC machine tools. It has more than 40 years of research and development and manufacturing basis for machine tools and has vertical machining centers. Rich experience in manufacturing. In response to the current situation of domestic 3C product processing machine tool research and development, in 2009, China Machinery Industry Quality Management Association awarded Hanchuan Machine Tool Group Co., Ltd.'s "Hanchuan" brand vertical machining center (see Figure 1) XH714D, XH715D, XH716D as "National Machinery" Industrial customer satisfaction products." Our company's vertical machining center table dimensions (width × length) cover 400mm × 900mm, 520mm × 1 200mm, 650mm × 1 400mm, 880mm × 2 160mm in various medium and small specifications, the maximum spindle speed of 8 000r / m In, the fast moving speed is available in 20 000mm/min and 36 000mm/min, which is widely used in machinery manufacturing and other industries.
