This machine tool has a unique and durable rigid structure. After repeated simulations and calculations of engineering mechanics, a solid bed structure was designed to meet the engineering requirements of doubling rigidity and streamlining quality. The machine tool has fully hardened moving slide rails, combined with precision grinding processing, to achieve satisfactory precision quality. It is not only suitable for the processing of plates, disks, shells and precision parts, but also suitable for mold processing. The machine tool is equipped with an automatic tool changing system (ATC), a fully enclosed protective cover, an automatic lubrication system, a cooling system, and a portable manual operating device (MPG). After the parts are clamped once, they can complete multi-process processing such as milling, boring, drilling, expanding, reaming, and tapping. It has a high degree of automation, strong reliability, simple, convenient and pleasant operation, beautiful and elegant overall shape, and high degree of electromechanical integration. advantage.
