Makino’s 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 and V99L provide the speed, accuracy and stability needed to tackle large molds and dies effectively,” says Bill Howard, VMC product manager. “Most importantly, both come with Makino’s unmatched expertise in the die/mold manufacturing market.”
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.
“When you’re dealing with large workpieces, stiffness and rigidity can make a huge impact,” Howard says. “Finishing times can last several days, the workpieces can be very heavy and hard to set up, and eliminating steps like stress relieving or having the ability to hard mill can save huge amounts of time and money. It takes a serious machine and serious know-how to machine large molds efficiently. That’s what the V99 and Makino’s application engineers provide.”
