        A unique and important position in manufacturing mould with product research and development, innovation and production, an important symbol of the mold manufacturing capacity and the level has become the national innovation ability. Mold manufacturing equipment is good or not directly related to the die level of technology. The development of mold equipment industry to promote the progress of mold industry, the latter also put forward more requirements on processing equipment. Luo Baihui pointed out that, along with the more precise die manufacturing, with the high-speed, complex, intelligent, and environmental protection become the mainstream trend of the current world machine tool manufacturing, mold manufacturing put forward higher requirements on equipment, technology. Requirements of NC machine tools to meet the requirements of high-speed, high dynamic accuracy, high rigidity, thermal stability, high reliability, network and related control system are personalized, all kinds of advanced software to the overall operation of machine tools to realize the openness, compatibility.

        The current machine tool equipment manufacturing enterprises focus on the following several aspects of the corresponding tooling modification, development to meet the requirements of precision and automation trend.

        1 machine tool large

        The high productivity of molding parts is large and parts requirements of multi cavity mold, the mold is large, large tonnage of large mould of up to 100 tons, a few hundred die cavity, thousands of cavity mold processing equipment, requirements with large working table, and at the same time to increase the Y axis and Z axis travel, and has large bearing, high rigidity, high consistency.

        2 machine tool rigidity is high

        Die steel material hardness mold machining high, in order to ensure the machining accuracy and surface quality, high speed machine tool for mold manufacturing must have high dynamic and static stiffness, in order to improve the accuracy of machine tools, precision tracking and anti vibration ability.

        3 prominent compound machining performance

        The complex cavity and multifunctional composite mould, with complex shape of parts, must improve the level of mold design and manufacturing, multi-functional composite mold a variety of trench, a variety of materials forming or assembling components in a mold, requires a large amount of processing programming procedures, with high hole cavity integrated cutting ability and high stability, improve the processing difficulty.

        In order to achieve the 3D surface of high precision, high speed and high stability, multi axis, a cutting ability of comprehensive deep cavity good machine adopts five axis linkage processing center, in addition to the three coordinates of linear motion, and two rotating coordinates of the feed movement. The milling head or table can turn into a joint axis, which is suitable for the processing of the mold cavity surface with complex parts.

        Composite processing is one of the development direction of the mould processing. Although the machining center has many machining process can be combined in one machine, but it still can not adapt to the mold processing, the processing method of different principle of machining and electrical, chemical, ultrasonic, composite, composite processing has more than two kinds of process characteristics in the mould manufacturing will have broad application prospects.

        4 high speed milling capacity

        Fine mold processing the high speed and high power high-speed processing has become the direction of development, mould processing in high speed milling has showed great superiority. Cavity and other parts, mold parts rough finishing often done in clamping a workpiece, the spindle power to big, spindle power medium size mold milling machine and machining center often 10~40kW, some even higher. High speed milling can be processed high hard materials, machining, cutting force, workpiece temperature has the advantages of small deformation, the mold enterprises pay more attention to the high speed machining.

        5 dynamic accuracy of safety and environmental protection

        High dynamic accuracy. With the machine high rigidity, thermal stability, high reliability, high dynamic accuracy and quality control system to realize the 3D surface of high precision machining mould.

        Combined machining technology and the green product technology will be taken into consideration when purchasing equipment in enterprise. Radiation, medium selection of EDM machine tool will be the factors of safety, environmental impact, EDM milling technology can be developed in the future field of die machining.
