When your parts demand complex 3D contouring, undercuts, and tight positional tolerances, standard 3-axis setups just won’t cut it. That’s where the GREBO FMC series 5-axis machining center models (FMC170, FMC320, and FMC650) come into play.
Instead of just bolting a rotary table onto a standard mill, we engineered the FMC series around a high-rigidity base and integrated Taiwan direct-driven rotary tables. Investing in a high-quality 5-axis machining center is the most effective way to eliminate secondary setups and drastically reduce cycle times for complex geometries.
Whether you need the compact high-speed FMC170 for small medical parts, or the heavy-duty FMC650 with 45mm roller guideways for large aerospace components, our
5-axis machining center series is built to handle your toughest contouring challenges in a single clamping.
Why Choose the GREBO FMC 5-Axis Machining Center Series?
- True 5-Axis Kinematics: Equipped with Taiwan direct-driven rotary tables (B/C axis ±110°/360°) for zero-backlash, high-dynamic contouring.
- Heavy-Duty Rigidity: The FMC650 features 45mm roller linear guideways, absorbing massive cutting forces during heavy roughing of titanium or steel.
- High-Speed Spindle Options: From the 20,000 rpm BT30 spindle on the FMC170 for fine finishing, to the 15,000 rpm BBT40 spindle on the FMC650 for balanced milling.
- Superior Chip Evacuation: Dual chip removal system (Chain-type + Spiral-type) prevents chip buildup in deep-cavity 5-axis machining.
- Premium Control Systems: Standard Siemens 840D SL, with Fanuc, Mitsubishi, and Syntec available to match your shop’s programming ecosystem.
- Thermal Stability: Standard spindle oil cooler and cabinet air conditioner ensure micron-level accuracy during long, unattended runs.
- Full Enclosure & Safety: Fully closed covers with safety interlocks, protecting operators while containing coolant and chips.

Real-World Applications of FMC 5-Axis Centers
The GREBO FMC series isn’t just about spinning 5 axes at once; it’s about solving real manufacturing bottlenecks. By upgrading to a modern 5-axis machining center, shops can drastically reduce lead times for complex geometries. These machines are transforming production floors in:
- ✅ Aerospace & Defense: Machining monolithic structural frames, blisks, and turbine blades from solid titanium or Inconel blocks.
- ✅ Medical Implants: The FMC170’s 20,000 rpm spindle is perfect for fine finishing orthopedic knee and joint implants from cobalt-chrome alloys.
- ✅ Complex Mold & Die: Deep-cavity 3D mold cores and impellers where long-reach tools would normally chatter on a 3-axis VMC.
- ✅ Automotive Prototyping: Rapid iteration of complex cylinder heads, valve bodies, and custom suspension components without dedicated fixtures.
For shops looking to optimize their multi-axis strategies, industry organizations like
AMT – The Association For Manufacturing Technology provide excellent insights into 5-axis workflow integration and automation.
If your current production involves complex geometries that require multiple setups, it might be time to upgrade. Explore our
