CHIRON Group presents innovative manufacturing solution  

“Innovations for future demands – explore our machining world premiere” – this is the motto behind the latest manufacturing solution from the CHIRON Group. At the heart of OPEN HOUSE 2025 is the world premiere of the Micro5 XL, introducing a new dimension in micromachining with maximum precision, dynamics and resource efficiency. The entire line-up could be experienced in Tuttlingen from May 13 to 15, 2025.

Micro5 XL – premiere for micromachining in a new dimension

What began with the Micro5 as a highly dynamic machining center for the finest precision parts is now being continued in a pioneering way: With the Micro5 XL, the CHIRON Group is scaling up the successful concept for further demanding applications in medical and precision technology, electronics and mold and die manufacturing.

Whether bone plates or knee inlays, bracelets or connectors, whether titanium, stainless steel or precious metals: the new micromachine processes complex, sophisticated geometries and different materials with maximum dynamics, precision and minimum cycle times.

The name Micro5 XL is, explains Senior Product Manager Michael Wurster, “not a contradiction, but a deliberate choice. As with the Micro5, the 5 stands for the ideal ratio of milling center to workpiece – in this case 600 mm to 120 mm cubic capacity. And XL, because the machining center stands for a new dimension in micromachining in several respects: for more travel distance, significantly higher cutting performance and maximum flexibility.”

A common feature with the Micro5 is its minimal footprint, which is just 1.7 m² for the Micro5 XL including magazine for up to 100 tools and peripherals. The tools are inserted via a 4-fold gripper with short chip-to-chip times and are used over their entire length thanks to machining strategies with high axial and low radial infeeds.

The Micro5 XL is operated entirely from the front and with a clear view of the process, even in the version with an integrated handling system. In this version, several machines can be arranged close together. This not only saves the cost-intensive resource of production space but also enables very ergonomic operation. The operating logic is consistent: Anyone who can program the micromachining center can also control the automation intuitively.
