In today’s competitive mold manufacturing landscape, precision and efficiency are no longer optional—they’re essential. For companies working with complex graphite electrodes, traditional 3-axis machining often leads to cumulative errors from part repositioning. That’s where the FH855L RTCP 5-axis vertical machining center from Ningbo Kebao CNC Machinery Co., Ltd. steps in—not just as a machine, but as a strategic solution.
RTCP (Rotational Tool Center Point) technology ensures that regardless of how the rotary table moves, the tool tip always stays on the programmed path. This eliminates the need for manual recalibration after each rotation—something that can cause up to 0.03 mm variation in high-precision graphite parts when done manually.
For example, one customer in the automotive mold sector reported reducing post-processing polishing time by 40% after switching to RTCP-enabled multi-face machining on their FH855L unit—simply because surface consistency improved across all five sides without physical handling.
| Parameter | Optimized Value for Graphite | Impact |
|---|---|---|
| Spindle Speed | 12,000–18,000 RPM | Reduces chipping & improves finish |
| Feed Rate | 1500–2500 mm/min | Balances throughput and edge quality |
| Depth per Pass | 0.2–0.5 mm | Prevents tool deflection in brittle materials |
A mid-sized die-and-mold shop in Germany used the FH855L to produce multi-sided graphite electrodes for EDM processes. By leveraging the machine’s built-in multi-face联动 programming feature, they reduced setup changes from 5 times per part to just 1—and saw a measurable drop in scrap rate from 8% to 2.1%.
This wasn’t magic—it was smart use of RTCP combined with optimized toolpaths. The key? Letting the machine do what it does best: keep the tool centered while rotating, so human error doesn’t creep in.
Unlike many competitors who offer “5-axis” capabilities without true RTCP support, the FH855L delivers real-time compensation based on actual axis movement—not just pre-set offsets. It’s this level of control that allows engineers to focus on design innovation rather than fixing mistakes caused by poor alignment.
Whether you're a junior engineer learning your first multi-face program or an expert optimizing for ultra-fine finishes (surface roughness Ra ≤ 0.8 μm), the FH855L offers a scalable platform that grows with your team’s skill level.
