The MT1250B specializes in high-precision machining of medium-to-long workpieces, supporting a maximum rotation diameter of 520 mm and a machining length of 1250 mm. Equipped with a 12,000 rpm high-speed milling spindle and a 21 kW variable frequency motor, coupled with advanced five-axis linkage technology, it ensures both precision and efficiency.

The MT1250B 5-axis CNC turning and milling machine features a B-axis with a large rotation angle of ±120 degrees and a C-axis with extremely high positioning accuracy. It also includes an automatic tool changer with a capacity of 60 tools. Its spacious operator interface and easy maintenance significantly enhance operational convenience and production flexibility. The main and sub-spindles support simultaneous machining, with maximum speeds of 2500 rpm and 4300 rpm, respectively, meeting diverse machining needs.

The MT series horizontal 5-axis mill-turn center features a rugged and durable design, making it ideal for multi-process machining of automotive parts, aerospace applications, and complex molds. Its exceptional rigidity and dynamic performance ensure excellent surface quality and dimensional stability for every part. The MT1250B integrates multiple functions into one, simplifying the processing process, saving time and costs, and is an ideal choice to help manufacturing companies improve their intelligence level.
