"Innovations for future demands – explore our machining world premiere" is the guiding theme for the latest manufacturing solutions from the Chiron Group. The focus of the Open House 2025 was the world premiere of the Micro5 XL for a new dimension in microprocessing.

What began with the Micro5 as a highly dynamic machining center for the finest precision parts now finds its groundbreaking continuation: With the Micro5 XL, the Chiron Group scales the success concept for further demanding applications in medical and precision engineering, electronics, and tool and mold making.

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

The designation Micro5 XL is not a contradiction but deliberately chosen. As with the Micro5, the 5 represents the ideal ratio of milling center to workpiece—here, 600 to 120 millimeters in volume. And XL, because the production center stands for a new dimension in microprocessing in several respects: for more travel, significantly higher machining performance, and maximum flexibility.

Commonality with the Micro5 is a minimal footprint, which for the Micro5 XL, including a magazine for up to 100 tools and peripherals, is only 1.7 square meters. The tools are changed via a 4-fold gripper with short chip-to-chip times and are used along the entire length thanks to machining strategies with high axial and low radial infeed.

The operation of the Micro5 XL is completely from the front and with a clear view of the process, even in the version with an integrated handling system. In this configuration, multiple machines can be positioned closely together. This not only conserves the costly resource of production space but also enables very ergonomic operation. The operating logic is consistent: anyone who can program the micro machining center can also intuitively control the automation.

Topspeed in Series

With the DZ 22 W speed+, the Chiron Group expands its portfolio with a particularly dynamic variant of the twin-spindle 5-axis production center. The new version with a 600-millimeter spindle distance is designed for the economical complete machining of large parts in series. With even more productivity, optimized machine structure, and significantly reduced non-productive times.

The performance data: a 20 percent higher acceleration and a 40 percent improved jerk behavior for significantly faster achievement of maximum speed during direction changes—important, for example, when threading. Added to this is the core component, the in-house developed motor spindle with a ramp-up time of 0.5 seconds, and a chip-to-chip time of 2.0 seconds. All these factors contribute to a significantly accelerated machining process.

Increased productivity is enabled through targeted design measures. With the same electrical drive power, significantly higher dynamics could be achieved – without compromising precision or process stability.

The demands on series production are continuously increasing. The DZ 22 W speed+ delivers a decisive boost in process efficiency, significantly reduces non-productive times, and ensures that every second of machining time is optimally utilized.

Power, Precision and Productivity

The expert audience was able to see these qualities for themselves at the Open House 2025. In live operation, the FZ 19 S five axis produced struts for an aerospace chassis assembly with precision tools from cooperation partner Mapal. For machining demanding materials—here, titanium Grade 5—the machining center is available with an HSK-A100 interface and a maximum spindle torque of 408 Newton meters.

Armrests, brackets, engine mounts, or airfoils are further examples from the aerospace application field where the machine variant of series 19 showcases its strengths in solid material machining. For complex parts or part variants, the largest magazine for up to 196 tools is recommended.

The FZ 19 S five axis impresses with large travel paths—850 millimeters in X, 960 millimeters in Y, and 700 millimeters in Z. This makes it ideal for components with a diameter of up to 820 millimeters. This optimal ratio of working space to workpiece dimension, combined with perfectly matched Chiron Group spindles, enables highly precise and particularly dynamic machining.
