Okuma MILLAC 761V II VERTICAL MACHINING CENTER

This vertical machining center features a robust 70.870" x 28.350" table capable of supporting workpieces up to 4,400 lbs, making it ideal for heavy-duty machining applications. The machine is equipped with a vertical spindle featuring an NST #50 taper (with #40 taper as an option), delivering up to 25 HP (30-minute rating) and a maximum spindle speed of 4,000 RPM (6,000 RPM optional). The spindle’s high torque and power ensure efficient material removal and precision in demanding operations. Tooling is managed by a 36-station automatic tool changer (expandable to 54 stations), with a rapid tool change time of 2.5 seconds and a chip-to-chip time of 6.0 seconds, maximizing productivity. The machine supports optional pallet changers with up to 2 pallets for increased throughput. It operates on 3 axes (expandable to 4 axes), with X, Y, and Z travels of 60.630", 29.920", and 25.980" respectively. Maximum feed rates reach 471 ipm, while rapid traverse rates are 52 ipm on all axes, ensuring fast and accurate positioning. The design does not include support for index or rotary tables, focusing instead on high-capacity, high-speed machining for large and heavy workpieces. This machining center is engineered for reliability, precision, and versatility in industrial environments.
