Overview
The Chiron MILL 800 is a universal vertical machining center designed for productive machining of medium-sized components. The MILL series represents Chiron's expansion beyond their traditional compact high-speed platforms into larger work envelopes, targeting shops that need Chiron precision and build quality for parts too large for the FZ series.
The MILL 800 features X/Y/Z travels of approximately 800 x 630 x 550 mm, a significant step up from the compact FZ 12 and FZ 16 platforms. The motorspindle offers options up to 20,000 RPM with HSK-A63 interface for versatile high-speed machining, and an HSK-A100 variant with higher torque for steel and titanium cutting. The vertical moving column design provides structural rigidity and excellent chip evacuation.
The machine accommodates workpieces up to approximately 900 mm diameter and 600 kg, making it suitable for medium-sized aerospace structural components, mold and die work, and general precision machining. The tool magazine holds up to 60 tools with Chiron's pick-up changer system. The machine bed construction ensures thermal stability and consistent accuracy across the full travel envelope.
The MILL 800 runs on Siemens SINUMERIK 840D sl and can be configured with automation interfaces for pallet loading. Unlike the compact FZ series which focuses on small-part production speed, the MILL 800 targets shops needing a versatile medium-envelope machining center with Chiron's German engineering quality. Competitors include the DMG Mori CMX 800 V, Mazak VTC-800/30SR, Okuma MB-80V, and Haas VF-4. New MILL 800 machines typically price between $300,000 and $425,000.

Strengths & Limitations
Strengths
- 800 x 630 x 550 mm travel provides a larger work envelope than any Chiron FZ series machine, accommodating medium-sized precision components
- Vertical moving column design delivers structural rigidity with excellent chip evacuation for productive machining
- Up to 20,000 RPM HSK-A63 spindle provides versatile high-speed capability across aluminum, steel, and general-purpose applications
- 900 mm workpiece diameter and 600 kg capacity open Chiron quality to parts beyond the FZ series work envelope
- 60-tool magazine handles complex multi-operation parts without interrupting production for manual tool loading
- German engineering quality and Chiron's precision standards in a more accessible MILL series price range
Limitations
- The MILL 800 uses ball-screw drives rather than the linear direct drives available on premium Chiron FZ series machines
- Chiron's North American service network is smaller than Mazak, DMG Mori, Haas, or Okuma for VMC service and support
- Starting price around $300,000 is a premium over comparable VMCs from Asian manufacturers with similar travel ranges
- Without the compact FZ series gantry design, the MILL 800 has a larger footprint relative to its rapid traverse speeds
- HSK-A100 high-torque spindle option adds significant cost for shops primarily cutting hard materials

Frequently Asked Questions
01
New MILL 800 machines typically price between $300,000 and $425,000 depending on spindle selection, tool magazine size, and options. This positions the MILL 800 as a premium VMC above Haas and similar to entry-level DMG Mori or Okuma platforms, but with Chiron's German build quality.
02
The MILL 800 offers significantly larger travels (800x630x550 vs 550x400x425 mm) for bigger parts. The FZ 16S provides linear direct drives and a more compact footprint for maximum dynamics on smaller parts. Choose the MILL 800 for larger parts; choose the FZ 16S for highest-speed small-part production.
03
The standard MILL 800 is a 3-axis VMC. The MILL 800 Five Axis variant adds a swivel rotary table for simultaneous 5-axis capability. If you need 5-axis, specify the MILL 800 Five Axis or MILL 800 Five Axis Baseline configuration.
04
The Haas VF-4 is significantly less expensive with a slightly larger work envelope. The MILL 800 provides superior build quality, better thermal stability, tighter tolerances, and higher spindle speed options. The Haas wins on price and service network availability; the MILL 800 wins on precision and production consistency.
05
Yes. The MILL 800 accepts automation interfaces for pallet changers and robotic loading. Chiron offers integration solutions for production cells. The vertical moving column design provides good access for automated part loading from the front of the machine.
