Makino’s (Mason, OH) V99 and V99L vertical machining centers (VMC) are engineered to provide superb accuracy and high-speed performance previously unobtainable with large die/mold milling machines. These capabilities of the V99 and V99L help eliminate or reduce benchwork and post-production polishing on large die and mold work. The V99 has an X-, Y-, and Z- axes of 59 x 39.4 x 31.5 inches (1,500 x 1,000 x 800 mm), with rapid traverse and cutting federates of 787 IPM (20,000 mm/min.). A large worktable of 70.8 x 39.4 inches (1,800 x 1,000 mm) accepts a maximum workpiece of 70.8 x 39.4 x 25.6 inches (1,800 x 1,000 x 650 mm) weighing up to 8,800 pounds (4,000 kg). The V99 is a rugged 50,692-pound (23,000 kg) machine that is 15.4 feet wide x 13.5 feet deep x 11.5 feet tall (4,700 x 4,100 x 3,500 mm). The V99L has an X-, Y-, and Z- axes of 78.7 x 39.4 x 31.5 inches (2,000 x 1,000 x 800 mm), with rapid traverse and cutting federates of 787 IPM (20,000 mm/min.). A large worktable of 90.5 x 39.4 inches (2,300 x 1,000 mm) accepts a maximum workpiece of 90.5 x 39.4 x 25.6 inches (2,300 x 1,000 x 650 mm) weighing up to 8,800 pounds (4,000 kg). The V99L is a rugged 57,304-pound (26,000 kg) machine that is 17.1 feet wide x 13.5 feet deep x 11.5 feet tall (5,200 x 4,100 x 3,500 mm). Both machines come with a #40 taper 20,000-RPM or a #50 taper 12,000-RPM spindle as standard equipment. This accommodates a maximum tool size of 4.7 inches (120 mm) in diameter by 11.8 inches (120 mm) in length and weighing 17.6 pounds (8 kg) on the #40 taper - or 5.7 inches (145 mm) in diameter by 15.7 inches (400 mm) in length and weighing 44 pounds (20 kg) on the #50 taper. An HSK A100, 18,000 RPM spindle is optional, as is five-axis capability. The V99 and the V99L incorporate 0.05 micron scale feedback on all axes—providing a positioning accuracy of ±0.000060 inches (±0.0015 mm) and repeatability of ± 0.000040 inches (±0.001 mm) for superb positioning and contouring accuracy for continuous machining of large workpieces.
