Overview

The Chiron MILL 800 Five Axis Baseline brings 5-axis simultaneous capability to Chiron's MILL platform in a standardized Baseline configuration. The MILL 800 is designed for universal 5-axis machining of medium-sized components, offering a larger work envelope than the compact FZ series while maintaining the precision and dynamics that define Chiron machining centers.

The MILL 800 Five Axis features X/Y/Z travels of approximately 800 x 630 x 550 mm, a significant step up from the FZ 16S and FZ 19S series. The 5-axis configuration uses a swivel rotary table for simultaneous 5-axis machining with a motorspindle reaching 20,000 RPM with HSK-A63 interface. The larger work envelope accommodates workpieces up to approximately 900 mm diameter and 600 kg, opening the machine to parts that smaller Chiron 5-axis platforms cannot handle.

The vertical moving column design provides structural rigidity and thermal stability. The machine bed construction ensures consistent accuracy across the full travel range. The tool magazine holds up to 60 tools with pick-up tool change. The Baseline configuration offers a standardized feature set that reduces lead time and cost compared to fully custom Chiron builds.

The MILL 800 Five Axis Baseline targets shops that need a capable 5-axis platform for medium-sized parts without the premium of a fully optioned MILL 800. It competes with the Hermle C 42 U, DMG Mori DMU 80, Okuma MU-5000V, and Mazak VARIAXIS i-700. New MILL 800 Five Axis Baseline machines price between $375,000 and $500,000.

Strengths & Limitations

Strengths

800 x 630 x 550 mm travel provides a significantly larger work envelope than the FZ series, accommodating medium-sized 5-axis components
Baseline configuration delivers Chiron 5-axis capability at a more accessible price point with shorter lead times than custom builds
900 mm workpiece diameter and 600 kg capacity open the machine to parts too large for the FZ 16S and FZ 19S platforms
Vertical moving column design ensures structural rigidity and thermal stability across the full work envelope
20,000 RPM HSK-A63 spindle provides versatile performance for aluminum, steel, and general-purpose 5-axis machining
Standardized Baseline specification means faster availability and predictable pricing for capacity expansion

Limitations

Baseline configuration limits customization — shops needing specific spindle options or automation may need the full MILL 800
Ball-screw drives in the Baseline version lack the backlash-free performance of linear direct drives available in premium Chiron machines
Chiron's North American service infrastructure is smaller than Mazak, DMG Mori, or Okuma, affecting support accessibility
At $375,000+, the MILL 800 Baseline is priced above comparable Asian-built 5-axis machines with similar travel ranges
60-tool magazine may be limiting for complex multi-operation parts that require extensive tooling

Best For

Aerospace manufacturers producing medium-sized structural components, ribs, and fittings that exceed the FZ series work envelope Mold and die shops machining medium-sized tooling components requiring 5-axis access and excellent surface finish General precision machining shops needing a universal 5-axis platform for diverse medium-sized components Medical device manufacturers producing larger implants, prosthetics, and surgical instruments requiring 5-axis geometry Energy and industrial equipment manufacturers machining turbine components, valve bodies, and precision housings Shops expanding 5-axis capacity who want Chiron quality at the Baseline price point with faster delivery

Frequently Asked Questions

01 What does a new Chiron MILL 800 Five Axis Baseline cost?

New MILL 800 Five Axis Baseline machines price between $375,000 and $500,000. The Baseline configuration saves significantly compared to a fully optioned MILL 800 while delivering the same fundamental 5-axis machining capability.

02 How does the MILL 800 compare to the FZ 16S?

The MILL 800 offers significantly larger travels (800x630x550 vs 550x400x425 mm) and workpiece capacity (900mm/600kg vs 700mm/360kg). The FZ 16S counters with linear direct drives and a more compact footprint. Choose the MILL 800 for larger parts; choose the FZ 16S for maximum dynamics on smaller parts.

03 What does Baseline mean for the MILL 800?

Baseline is Chiron's standardized-configuration product line with pre-selected options that reduce lead time and cost. The MILL 800 Baseline comes with a fixed specification covering the most common 5-axis requirements, rather than a custom configuration built to individual order.

04 Can the MILL 800 Baseline handle steel and titanium?

Yes. The 20,000 RPM HSK-A63 spindle handles steel and titanium with appropriate tooling and cutting parameters. For shops primarily cutting these materials, the full MILL 800 with HSK-A100 high-torque spindle option may be more productive for heavy roughing.

05 How does the MILL 800 compare to the Hermle C 42 U?

Both are premium 5-axis machines with similar work envelopes. The Hermle C 42 U is an established leader in mold and die with excellent surface finish. The MILL 800 offers Chiron's production-oriented design with faster rapid traverse. The Hermle has broader North American service; the MILL 800 Baseline offers a more accessible price point.

06 What automation is available?

The Baseline configuration includes standard interfaces for automation integration. Chiron offers pallet changers and robotic loading solutions for the MILL platform. Custom automation integration may require stepping up from the Baseline to the full MILL 800 specification.
