Targeting markets and meeting today's and tomorrow's requirements with innovative manufacturing solutions – that is what the CHIRON Group stands for. One area that is gaining increasing importance is high-dynamic micro machining of precision parts with short cycle times and tolerances in the micrometer range. For these tasks, the company offers two tailored solutions: the proven Micro5 and – for an expanded application spectrum – the new Micro5 XL.
Both models set new benchmarks in the machining of demanding components – for example, in medical technology, precision and fine mechanics, and everywhere where dynamics and highest accuracy are required. A central feature is the extraordinary ratio between the structural dimensions of the machine and the maximum workpiece size. For the Micro5, this means: a milling center of 250 mm to a workpiece volume of up to 50 mm, while the Micro5 XL has 600 mm for the heart of the machine to a maximum volume of 120 mm. This ratio is unique, combining extreme compactness with outstanding performance.
Benchmark in Micro Machining: the Micro5
Whether medical components, watch parts, fine jewelry, or delicate components for precision and micro mechanics: The Micro5 is the perfect choice for machining small, high-quality workpieces. What began as a small revolution has developed into the most successful micro machine on the market.
With a weight of only 550 kg and a 230-V connection for true 'Plug and Play', the Micro5 can be flexibly integrated into almost any manufacturing environment – even directly at the workplace. Despite its ultra-compact footprint, it impresses with high static and mechanical stiffness and delivers the required precision for the most demanding geometries.
Micro Machining in a New Dimension: the Micro5 XL
At EMO 2025 in September, the CHIRON Group presented the Micro5 XL – a true crowd puller. But what distinguishes the new micro machine beyond the proven strengths of the Micro5 from other solutions? Why 'a new dimension'? XL stands for more travel, higher cutting performance, and maximum flexibility, thus offering new possibilities in 5-axis simultaneous HSC machining, for example, of medical products like knee inlays or bone plates, as well as larger watch cases or bracelets.
The Micro5 XL machines volumes up to 120 mm on a footprint of only 1.7 m² – with high-dynamic BC-5-axis kinematics, spindle speeds of 40,000 or 50,000 rpm, and acceleration values of up to 900 m/s³. This enables outstanding path and machining speeds with maximum precision.
Perfectly coordinated: the automation solutions
More productivity and autonomy in series production – for this, the Micro5 can be combined with the handling system Variocell UNO. It loads and unloads up to two machines, takes over the automatic handling of workpieces and tools, and offers space for up to ten pallets. The tool change takes place in under five seconds.
For the Micro5 XL, the CHIRON Group offers three variants for a productive combination: a pallet automation and two variants of workpiece automation – with a robot or, with the new Variocell PICK&PLACE, with linear handling. The system transports raw parts from the storage pallets to the clamping device and places the finished parts back in storage. The decisive advantage for intuitive handling and short setup times: machine and automation follow the same operating logic. Operation is from the front with direct visibility of the machining process. This allows multiple manufacturing units to be placed closely together – production simply grows with demand.
