Horizontal Machining Center 5 axis Makino MCC2516-VG

The MCC2516-VG, while similar in many ways to Hi-Tech’s other MCC horizontal machining centers, offers Makino’s Variable Geometry (VG) technology for 2+3 cutting strategies. Using five axes, VG technology can lock the spindle into any 5-axis configuration for increased access to difficult feature geometries while retaining all the benefits of a 3-axis machine.

The MCC2516-VG handles workpieces up to 118.1 inches by 70.9 inches by 74.8 inches on pallets 118 inches by 63 inches. Its semi-floating slideway system delivers a top cutting feedrate of 16 meters per minute even in the company’s heaviest workpieces. This system sends compressed air between the table slideways to automatically adjust the pneumatic pressure to handle table load changes. As a result, slideway resistance is low, reducing lost motion for any size workpiece.

The high-rigidity spindle is supported by cylindrical roller bearings and delivers a maximum speed of 12,000 rpm. For 24/7 machine usage, the MCC2516-VG incorporates a patented Makino spindle core cooling system used to internally cool the rotating spindle, ensuring minimal thermal distortion and precise spindle positioning.

The MCC2516-VG is also equipped with Makino’s unique Super Geometric Intelligence (SGI.4) control system for coordinated error compensation in all three axes simultaneously. This on-the-fly, three-dimensional compensation lets the machine track precisely to programmed toolpaths on mold contours and complex geometries, even at five times or more the feedrates of conventional large machines.

“The MCC2516-VG’s machining capabilities deliver what we need and more: high accuracies with the added benefits of minimized setups, faster cycle times, longer tool life, limited bench work and easier programming,” says Schulte. “While 5-axis machining definitely has its place in other markets, two-plus-three machining is perfectly suited for our large mold applications.”
