YAMA SEIKI GOODWAY GV-780 VERTICAL MACHINING CENTER

This CNC vertical machining center is engineered for precision turning with a maximum spindle turning diameter of 32.280" and a turning length capacity of 25.900". It supports a maximum swing of 33.460", allowing large diameter parts to be machined without interference. The main spindle accommodates a standard 15.000" chuck diameter, with an optional 18.000" chuck for increased versatility. Powered by a 30 HP spindle motor operating at up to 2,000 RPM (optional 1,500 RPM), it ensures robust cutting performance for a variety of materials. Equipped with 12 tool positions in the turret, it supports single simultaneous cutting with a rotary tool motor rated at 7.5 HP and capable of 3,000 RPM, enabling additional milling or drilling operations. The vertical machining center uses 2 axes of motion for precision control — the X-axis with 19.600" travel and the Y-axis offering an extended 196" travel, complemented by 26.300" of Z-axis motion for axial movement. The maximum feed rate is 196 inches per minute, with rapid traverses reaching 787 inches per minute, optimizing machining cycle times. This combination of spindle power, axis travels, and tool capacity makes the machine suitable for mid-to-large diameter cylindrical components requiring both turning and auxiliary operations. The two-axis design addresses typical turning applications with enhanced tool flexibility via the rotary tool. The large Y-axis travel is notable, potentially for supporting a substantial or extended workpiece setup, while maintaining high feed and rapid traverse speeds for efficient production cycles.
