YAMA SEIKI BM-850 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a work envelope of 33.5" (X-axis), 23.6" (Y-axis), and 23.6" (Z-axis), supporting high-precision machining tasks. It is powered by a robust 20 HP spindle capable of speeds up to 8,000 RPM, utilizing a 40-taper spindle interface for enhanced rigidity and tool alignment. The Automatic Tool Changer (ATC) holds 36 tools, enabling complex machining without manual intervention, with a rapid tool change time of 1.3 seconds. The machine's table measures 41.3" by 23.6" and includes five standard T-slots, each 5/8" wide, accommodating a maximum load of 1,870 lbs for secure workpiece mounting. Rapid traverse rates reach 1,181 inches per minute, while cutting feed rates max out at 945 inches per minute, optimizing machining efficiency. The spindle nose to table distance adjusts between 4.9" and 28.5", allowing versatility in accommodating various workpiece sizes and tooling setups. Tool capacity includes a maximum weight of 17.6 lbs, diameter up to 3.54", and length up to 11.8". The machine requires 80 psi of air pressure at 4 scfm for operation. Overall dimensions are 140" wide, 100" deep, and 110" high, with a total weight of 14,330 lbs, ensuring a stable and rigid platform for precision work. Its extensive cutting time metric of 18,543 hours indicates durability and long-term reliability in industrial applications. This machine suits demanding environments requiring high speed, accuracy, and efficient tool handling for milling operations across multiple industries.
