The machine design integrates 8mm-fine pitch ball screws and 0.05-micron scale feedback, as standard features, thus enabling the F5 machine to provide superior precision. These features reduce variability during hours of continuous, tight-tolerance machining. The F5 offers positioning accuracies to within ±0.0015 mm and a repeatability of ±0.001 mm
The standard configuration of the F5 includes a highly productive 20,000-rpm, HSK-A63 spindle, which incorporates Makino’s patented core-cooling, under-race and jacket spindle temperature control system. The two-range spindle supplies unique, wide-range capability with the stiffness and rigidity at lower ranges for roughing operations, and vibration/chatter-free production of small details and fine features when utilising small tools at high rpm.
