With the wide promotion and application of new energy, wind power is the first to bear the brunt, green, environmental protection and energy conservation. Windmills stand on the vast land, becoming a beautiful scenic spot in many places.

With the application of wind power, wind power mold processing has also become a hot industry. Wind power molds are generally processed by substituting wood. Due to the large area of wind power blades, the model is also large, the surface is smooth, the height drop of the root is large, and the length is generally 37 meters to more than 80 meters. The requirements for mold processing accuracy are also high. Therefore, this requires that the machining accuracy of CNC machining center equipment should be high and the machining size should be large. This requires that the machining height of the five axis machining center is about 4 meters and 6 meters, and the machining length of the machine tool is about 90 meters. Such a large stroke span requires higher machining accuracy, which needs to be within ± 0.5mm.

For such a long-span machining stroke, the bridge gantry machining center is used in the speedpa five axis five linkage machining center, and the bed is welded with steel plates based on European and American processes, which has been treated for failure. In this way, the production strength of the equipment is stronger, and the processing accuracy is higher. While effectively ensuring the processing accuracy, the processing speed is effectively improved. The imported five spindle head and processing spindle can be used to fine process complex curved surfaces, ensure the surface finish of the workpiece, and meet the processing requirements of casting wood mold, glass fiber reinforced plastic turnover mold, etc.

The five axis five linkage machining center is suitable for the mold processing of wind turbine blades, and has significant advantages in the intelligent processing of new composite materials such as yacht ship models, cast wood models, lost foam molds, etc.
