MAMMOTH PROKING BN-70 HORIZONTAL MACHINING CENTER

Technical Description

The MAMMOTH PROKING BN-70 Horizontal Machining Center is engineered for high-capacity turning and machining operations, featuring a robust main spindle with a maximum turning diameter of 53.940" and a maximum turning length of 472.000". The spindle chuck diameter reaches 60.000", supporting large workpieces with a maximum swing of 70.470". Designed with a single main spindle, the BN-70 delivers 35 HP at 500 RPM, with an optional reduced speed of 400 RPM for specialized applications. The machine is equipped with a turret-style primary tool carrier, accommodating up to 6 turning tools, and allows for one simultaneous cutting tool operation. With a 2-axis configuration, the X-axis offers a travel of 53.940" and both the X and Z axes provide a maximum feed rate and rapid traverse of 236 ipm, ensuring efficient material removal and swift positioning. The Z-axis travel extends to 78.740" as standard, with an optional extension up to 472.000" to accommodate exceptionally long workpieces. This machining center combines heavy-duty construction with precise motion control, making it ideal for demanding production environments requiring large-part capacity, high rigidity, and reliable performance in horizontal turning and milling applications.
