Graphite—a material widely used in aerospace, automotive, and semiconductor industries—is prized for its thermal conductivity, electrical properties, and lightweight nature. However, its brittleness and abrasive characteristics make it notoriously difficult to machine without vibration, tool wear, or surface defects. For manufacturers aiming to scale production while maintaining high precision, selecting the right machining solution is critical.
Conventional milling setups often struggle with graphite due to inconsistent chip formation and heat buildup. According to industry benchmarks, up to 40% of graphite parts fail quality inspections when processed on standard vertical mills—mainly because of chatter marks, dimensional inaccuracies, and poor surface finish. The root cause? Inflexible spindle configurations that can’t adapt to complex geometries or varying feed rates across roughing and finishing stages.
The凯博数控 (Kebon CNC) FH1890L vertical machining center addresses these pain points head-on. With a multi-angle spindle system, Mitsubishi CNC control, and a generous 1,890 mm travel range, this machine enables seamless transitions between roughing and finishing operations—without compromising accuracy or cycle time.
Key Technical Advantages:
In a recent case study at an EV battery component manufacturer, the FH1890L reduced total machining time from 4 hours per part to just 2.6 hours. By leveraging its dual-spindle flexibility and optimized toolpaths, operators achieved consistent Ra values below 1.6 µm across all surfaces—even on thin-walled graphite electrodes.
For technicians, here’s a practical tip: Always use climb milling for graphite, and maintain coolant flow at 5–8 bar pressure to minimize dust accumulation and extend tool life. The FH1890L’s integrated chip conveyor system also helps reduce downtime by up to 25%.
By combining precise motion control, robust rigidity, and intelligent spindle management, the FH1890L delivers not only faster output but also higher consistency. This makes it ideal for OEMs seeking to meet tight delivery schedules without sacrificing quality standards—especially in markets like North America, Germany, and South Korea where precision is non-negotiable.
