In the competitive realms of new energy, battery manufacturing, aerospace, and precision tooling, manufacturers face increasing demands for complex parts made from challenging materials like graphite. Traditional three-axis machining centers often struggle in meeting these precision and efficiency standards due to frequent re-clamping and limited tool paths. Ningbo Kaibo CNC Machinery Co., Ltd addresses these challenges with its advanced FH855L RTCP Five-Axis Vertical Machining Center, dramatically reducing setups and boosting both productivity and part quality.
Processing complex geometries with high precision demands multiple orientations and setups, especially in materials like graphite which is brittle and sensitive to machining forces. Conventional three-axis machines require multiple clamps to access intricate surfaces, increasing human error risks and setup time. This not only extends production cycles but also causes variation in part quality, impacting yield rates negatively. In some cases, manufacturers face average setup times upwards of 3 hours per batch and scrap rates reaching 8–12%.
The FH855L integrates advanced Rotary Tool Center Point (RTCP) technology to optimize tool paths and machine kinematics, allowing simultaneous multi-axis movement and precise tool tip positioning. This capability diminishes the need for repositioning or reclamping by enabling access to complex geometries in a single setup. RTCP compensates for tool axis inclination dynamically, significantly improving repeatability and surface finish without sacrificing cycle times.
In practice, customers observe reduction in setups from typically 4–5 down to a single clamp, cutting changeover time by about 60%. Coupled with 60-second rapid tool changes, overall machining cycle time shrinks by 35–40%, allowing expedited deliveries.
| Performance Metric | Traditional 3-Axis | FH855L 5-Axis RTCP |
|---|---|---|
| Average Setups per Part | 4-5 | 1 |
| Setup Time (hours) | 3.2 | 1.2 |
| Cycle Time Reduction | — | 35-40% |
| Scrap Rate (%) | 8-12% | 2-4% |
| Repeatability (μm) | ±15 | ±5 |
A leading lithium-ion battery components manufacturer in Zhejiang province harnessed the FH855L to machine complex graphite current collector plates. Previously limited by defects from multiple reclamps and thermal distortion, the customer achieved a notable 65% improvement in first-pass yield after adopting the five-axis solution.
Additionally, the RTCP-enabled tool path optimization resulted in surface roughness improvements from Ra 1.6 μm down to Ra 0.6 μm, enhancing electrical conductivity and extending component lifespan. The client reported a 30% reduction in overall machining lead time, leading to faster order turnarounds and reduced operational costs.
Feedback highlighted the machine’s stable performance with graphite’s abrasive nature, as well as Kaibo’s pre-sale customization consultation and responsive global support network which ensured rapid deployment and minimal downtime.
Transitioning to a five-axis vertical machining center like the FH855L brings substantial competitive advantages beyond incremental productivity gains:
These factors collectively enhance factory throughput and profitability, making five-axis vertical machining an indispensable asset for advanced manufacturers.
