Overview

The Chiron Micro5 XL extends the Micro5 platform with a 120 mm machining cube, more than doubling the work envelope of the original Micro5's 50 mm cube. This larger capacity opens the machine to a broader range of precision components in medical technology, mold-making, electronics, and mechanical engineering while maintaining the sub-micron accuracy and high-speed dynamics that define the Micro5 family.

The Micro5 XL features a high-speed spindle reaching 60,000 RPM with significantly higher cutting performance than the standard Micro5. The extended travel distances accommodate workpieces that are too large for the original Micro5 but still require the precision and surface quality that only a dedicated micro-machining platform can deliver. Direct drives on all five axes provide backlash-free motion with high acceleration for dynamic simultaneous 5-axis machining.

The tower magazine holds up to 100 tools, a substantial increase over the Micro5's 60-tool capacity. This expanded tool storage supports complex multi-feature parts that require dozens of tool changes without operator intervention. The minimum footprint including peripherals is just 1.7 m2, making the Micro5 XL remarkably space-efficient for its capability.

Average energy consumption of approximately 3.7 kWh keeps operating costs low and heat generation manageable for temperature-controlled environments. The machine's granite-based construction provides the thermal stability and vibration damping essential for precision micro-machining. Chiron offers full automation integration including pallet systems for unattended production. Competitors include the Kern Micro HD, Willemin-Macodel 508MT2, and Roeders RXP 200 DS. New Micro5 XL machines price between $350,000 and $475,000.

Strengths & Limitations

Strengths

120 mm machining cube more than doubles the Micro5's work envelope, accommodating a wider range of precision components while maintaining micro-machining accuracy
100-tool tower magazine is exceptionally generous for a micro-machining platform, enabling complex multi-feature parts without manual tool intervention
1.7 m2 footprint including peripherals is remarkably compact for a machine with 120 mm cube capacity and 100-tool storage
Direct drives on all five axes eliminate backlash for sub-micron positioning accuracy during simultaneous 5-axis operations
3.7 kWh average energy consumption is extremely low, reducing operating costs and enabling deployment in temperature-controlled environments
60,000 RPM spindle with higher cutting performance than the standard Micro5 handles both micro-endmills and slightly larger tooling effectively

Limitations

120 mm machining cube is still very small compared to conventional 5-axis machines, limiting the platform to precision micro-components
Proprietary tool interface prevents use of standard HSK or BT toolholders, limiting tooling options to Chiron-compatible systems
Higher price point than the standard Micro5 may not be justified for shops working exclusively within the 50 mm envelope
Chiron's specialized service network for the Micro5 platform is limited outside of Europe, particularly in North America
60,000 RPM spindle is lower than the standard Micro5's 80,000 RPM, trading top-end speed for higher cutting torque and workpiece capacity

Best For

Medical device manufacturers producing larger implants, spinal cages, and orthopedic components that exceed the 50 mm Micro5 envelope Mold and die makers creating precision micro-molds for connectors, lenses, and miniature plastic components Electronics manufacturers machining housings, heat sinks, and structural components for sensors and micro-assemblies Watchmaking and luxury goods companies producing cases, bezels, and mechanical components requiring 5-axis precision Dental prosthetics manufacturers machining bridges, frameworks, and custom abutments from titanium and zirconia Precision engineering firms needing automated 5-axis production of small components with sub-micron accuracy requirements

Frequently Asked Questions

01 What does a new Chiron Micro5 XL cost?

New Micro5 XL machines typically price between $350,000 and $475,000 depending on automation integration, tool magazine configuration, and spindle options. The XL commands a premium over the standard Micro5 due to the larger work envelope, higher-performance spindle, and 100-tool tower magazine.

02 How does the Micro5 XL differ from the standard Micro5?

The Micro5 XL has a 120 mm machining cube versus 50 mm on the standard Micro5, a 100-tool tower magazine versus 60 tools, and higher cutting performance with a 60,000 RPM spindle. The XL's 1.7 m2 footprint is slightly larger. The standard Micro5 has a higher 80,000 RPM spindle speed for the smallest micro-endmills.

03 Can the Micro5 XL replace a conventional 5-axis machine?

No. The Micro5 XL is purpose-built for micro-machining within a 120 mm cube. It cannot replace a conventional 5-axis machine for general-purpose work. However, for shops producing precision micro-components, it delivers accuracy and surface quality that conventional machines cannot match.

04 What materials can the Micro5 XL machine?

The Micro5 XL handles all common engineering materials including titanium, stainless steel, cobalt-chrome, aluminum, brass, copper, and engineering plastics. The higher cutting performance compared to the standard Micro5 makes it more capable on harder materials like titanium and cobalt-chrome alloys used in medical implants.

05 What automation options are available?

Chiron offers pallet automation systems for unattended production, similar to the standard Micro5's 6-pallet system. The 100-tool magazine supports extended unattended runs. The machine can be integrated into larger automation cells with robotic loading for high-volume micro-component production.
