Makino's Variable Geometry (VG) equipment is designed for the machining of large dies and molds. The MCC-VG Series of horizontal machining centers provide simultaneous three-axis machining and slanted hole machining, accomplished by tilting the spindle at an optimum angle for access to the machining point.
The tilted spindle on the MCC-VG Series machines allows for the use of shorter tools to achieve high-efficiency machining. This prevents the spindle and the tool from colliding with the table.
Deep mold cavities and cooling holes can be machined in the same workpiece setup.
Slanted holes can also be machined continuously at various angles without changing the setup.
"The VG comes with Makino's patented through-coolant spindle technology, which is unique in the marketplace on an angled-head machine," said a Makino spokesperson. This technology enhances the speed and accuracy of drilling angled holes due to the natural flushing out of the chips.
An automatic non-contact tool-measuring device (retract type) accurately measures and corrects the position of the tool tip. Even when machining at different spindle angles, level differences at the seams of finished surfaces are minimized.
The position of the tool tip is measured with accuracy under actual machining conditions, and compensation for spindle thermal distortion is automatically applied in three dimensions as machining proceeds. This function works to minimize level difference in finished surfaces and its result is that the step between each machined surface is within 3um.
Makino's patent-pending tool tip position calculation function is used when drilling slanted holes. It measures a calibration value in advance for every tilt angle of the spindle. Those values are used to correct the tool tip position automatically after the spindle has been indexed. This eliminates the need to measure the tool length each time after indexing the spindle.
The MCC-VG has a spindle speed of 12,000 min-1. Spindle taper hole is 7/24 taper No. 50, and the spindle drive motor is 18.5/11kW (40% ED/cont.). The spindle is supported by cylindrical roller bearings having an inner diameter of 100 mm, enabling it to execute a wide range of jobs from roughing to finish machining.
Makino's spindle core cooling system is used to cool the rotating spindle directly from the inside. This spindle core cooling system circulates a temperature-controlled cooling oil through the center of the rotating spindle. The temperatures of the spindle and the jacket are constantly coordinated so that the bearings can be optimally preloaded in all speed ranges.
The Makino MCC-VG Series delivers high acceleration even with a maximum table load of 15 tons. The table has a 3,000 x 1,600 mm working area. The Y- and Z-axes both adopt two ball screws and two drive motors, while the X-axis features two ball screws and four drive motors.
X-axis travel is 2,500 mm on the MCC2516VG, and 3,000 mm for the MCC3016VG. Y-axis travel is 1,600 mm on both the MCC2516VG and the MCC3016VG. Z-axis travel is 1,300 mm on both the MCC2516VG and the MCC3016VG. Rapid traverse and cutting feedrates (X/Y/Z-axis) are 16,000 mm/min. There is a 30-tool automatic tool changer, with a maximum tool weight of 20 kg and a maximum tool length of 550 mm. Maximum tool diameter is 125 mm.
