Makino F5

A new Makino F5 Pro 6 typically runs between $180,000 and $300,000 depending on configuration. A base machine with 20,000 RPM spindle and standard equipment starts around $180,000-$200,000. Adding the 30,000 RPM spindle, through-spindle coolant, Renishaw probing, and thermal compensation upgrades pushes pricing to $230,000-$260,000. A fully loaded machine with all options typically tops out around $280,000-$300,000. Used F5 machines from 2016-2021 typically sell for $100,000-$170,000 depending on spindle hours and configuration.

The F5 and PS95 serve different roles in Makino's lineup. The PS95 is a production-oriented VMC designed for high-speed material removal with faster rapids (36 m/min vs 20 m/min), a more powerful spindle (22 kW vs 15 kW), and larger travels (900 x 500 x 450 mm on both, but the PS95 emphasizes throughput). The F5 is the precision specialist with finer ball screws (8 mm vs 12 mm), higher-resolution scale feedback (0.05 vs 0.1 micron), and better positioning accuracy. Choose the F5 for mold finishing and precision work; choose the PS95 for production parts where metal removal rate matters more than ultimate accuracy.

Yes—hardened steel machining is the F5's primary design intent. The core-cooled spindle maintains thermal stability during extended finishing passes at high speeds in materials up to 62 HRC. The fine-pitch ball screws and high-resolution scale feedback ensure the cutter follows the programmed path with sub-micron fidelity, which is critical for achieving mirror-like finishes on hardened mold cavities. The SGI.5 contour control optimizes feed rates through complex 3D surfaces to maintain consistent chip load and surface finish quality. Most F5 owners report achieving Ra 0.1-0.2 micron finishes on hardened P20 and H13 tool steels.

SGI.5 (Super Geometric Intelligence version 5) is Makino's advanced contouring control algorithm. It processes the programmed toolpath and optimizes axis accelerations and feed rates in real time to maintain accuracy through complex curves and 3D surfaces. Where standard CNC controls slow down excessively at sharp corners and tight radii, SGI.5 maintains higher effective feed rates while keeping the cutter on the programmed path within the machine's accuracy specification. The result is shorter cycle times on complex 3D finishing passes without sacrificing surface quality.

Yes, especially with the 30,000 RPM spindle option. The F5 is widely used for graphite electrode production in EDM shops. The high spindle speed generates the surface speeds needed for clean graphite cutting with minimal chipping. Makino offers graphite-specific machine configurations with sealed way covers, dedicated dust extraction systems, and optimized cutting parameters. The precision positioning ensures electrode accuracy translates directly into EDM cavity accuracy. Makino also offers the dedicated F5 Graphite variant specifically optimized for this application.

Both machines target the precision VMC segment, but the Yasda YBM 640V occupies an even higher tier of accuracy. The Yasda uses hand-scraped guideways and achieves positioning accuracy under 1 micron, compared to the F5's +/-1.5 micron spec. The Yasda typically costs $350,000-$500,000 versus the F5's $180,000-$300,000. For shops doing the most demanding mold work—optical lenses, connector molds with sub-micron tolerances—the Yasda is the benchmark. For the majority of precision mold work, the F5 delivers accuracy that meets or exceeds requirements at a significantly lower price point.
