YAMA SEIKI BM-1200 VERTICAL MACHINING CENTER

This CNC machining center features a robust table measuring 51.2" x 23.6" with a maximum load capacity of 2,650 lbs, supporting heavy-duty workpieces. Its travel ranges are 47.2" along the X-axis, 23.6" on the Y-axis, and 26.8" vertically (Z-axis), with an adjustable spindle nose-to-table-top distance from 4.92" to 28.5" for versatile part accommodation. The spindle utilizes a CAT 50 taper, known for high rigidity and stability in heavy machining applications, operating at speeds from 65 to 6,000 RPM across low and high-speed ranges. Power is delivered by a two-speed gearbox-driven motor rated at 15 hp for 30 minutes and 20 hp continuous, ensuring consistent performance. The machine is equipped with a 30-position automatic tool changer (ATC) using assorted CT 50 tool holders, facilitating efficient tool management and reducing downtime. Rapid traverse rates are 945 IPM in the XY plane and 788 IPM vertically, with cutting feed rates varying from 39.4 to 393.7 IPM, optimizing both speed and precision. The CNC control system is a Fanuc 0iMD, supporting up to 4 simultaneous axes with advanced servo control and features such as backlash compensation, flexible feed gears, and high-speed interpolation for complex machining tasks. Additional capabilities include a 97-gallon coolant tank, pneumatic pressure requirements of 85 PSI, and a power supply of 220 V ±10%. The machine’s total weight is 16,093 lbs, reflecting its heavy-duty construction. This combination of specifications makes it suitable for large, precise, and complex milling operations in industrial environments.
