This part was produced on the new version of the F5 machine. The 20,000-rpm spindle enables vibration-less machining and the dynamic of the axis smooth control of the tool position.
The part was produced in 1.2083 steel featuring 58 HRC.
Four types of tools and a total of six tools were used (smallest radius 0.3 mm).
Machining time: 6 hours, 13 minutes
F5
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.
