Graphite machining demands precision, consistency, and tool stability—especially when producing components for EV batteries, aerospace, or medical devices. Traditional setups often struggle with dust accumulation, vibration sensitivity, and inconsistent surface finishes. That’s where the FH1890L vertical machining center, powered by Mitsubishi CNC technology, delivers measurable improvements in both efficiency and accuracy.
With a positioning accuracy of ±0.005 mm and rapid response times under 5 ms, Mitsubishi’s CNC system ensures minimal deviation during high-speed cutting—a critical factor for graphite’s brittle nature. In real-world tests at a leading battery manufacturer in Germany, this setup reduced part rejection rates from 7% to less than 1% over six months. For operators and engineers evaluating new equipment, that’s not just data—it’s confidence.
“We saw a 40% increase in throughput after switching to the FH1890L with multi-axis head options. It’s no longer about managing downtime—it’s about maximizing output.”
—— Stefan Weber, Production Manager, E-Motive GmbH
The true power of the FH1890L lies in its ability to switch between straight heads, right-angle heads, and universal heads without re-fixturing. This flexibility supports complex geometries common in graphite electrodes used in EDM processes. A case study from a Japanese mold maker showed that using interchangeable heads cut setup time by 60%, while improving surface finish from Ra 3.2 μm to Ra 1.6 μm.
For shop floor teams, this means fewer manual adjustments, lower risk of misalignment, and consistent quality across batches—even for irregular shapes like tapered cores or deep cavities.
Equipped with a travel range of 1200 x 800 x 800 mm and optimized feed rates up to 30 m/min, the FH1890L handles heavy roughing operations efficiently while maintaining precision in finishing passes. Its spindle torque (up to 120 N·m) and thermal compensation algorithms prevent chatter and ensure dimensional stability even in long runs.
This dual capability makes it ideal for shops handling mixed-volume orders—from prototype runs to production-scale jobs—all on the same machine.
