Overview
The Chiron Mill 400 Five-Axis is a compact vertical 5-axis machining center designed for high-accuracy production of small-to-medium precision parts in industries including medical technology, watch and optical manufacturing, aerospace sub-components, and electronics enclosures. It bridges the gap between Chiron's FZ-series micro-machining platforms and the larger Mill 1000 series, delivering 5-axis agility in a shop-floor-friendly package.
The Mill 400's swiveling rotary table design provides A-axis travel of ±120° and continuous C-axis rotation, enabling full 5-axis simultaneous interpolation on workpieces up to 400 mm in diameter. The rigid gantry-style column and symmetrical casting design minimize thermal deformation and maintain geometric accuracy across extended production shifts — critical for batch production of precision instrument components.
Chiron's high-torque spindle options for the Mill 400 range from 18,000 rpm standard to 30,000 rpm for high-speed finishing applications. Rapid traverse rates of 60 m/min in all linear axes keep non-cut time low, supporting the high-throughput production cycles the Mill 400 is designed for in automated cell environments.
The Chiron Mill 400 Five-Axis is offered as part of Chiron's scalable automation ecosystem, integrating with the PartMaster pallet handling system, linear robot interfaces, and the Chiron DataLine monitoring platform. This makes it well-suited to Industry 4.0 production environments where process transparency, traceability, and unmanned operation are requirements rather than options.

Frequently Asked Questions
01
The Mill 400 Five-Axis can accommodate workpieces up to ø 400 mm in diameter and 350 mm in height, with a maximum table load of 150 kg. It is designed for small-to-medium precision components rather than large structural parts.
02
Yes. The Mill 400 integrates with Chiron's PartMaster pallet automation system, linear robot loaders, and standardized robot cell interfaces. The machine's DataLine connectivity supports real-time monitoring and MES integration for full production traceability.
03
The Mill 400 has a smaller work envelope (400 mm table vs. 1,000 mm on the Mill 1000) and is targeted at precision small-part production. The Mill 1000 Five-Axis is designed for larger components typical of mold-making and aerospace, with higher payload capacity and a larger tool magazine.
04
The standard spindle delivers 18,000 rpm and is suited to steel, titanium, and stainless machining. An optional 30,000 rpm spindle is available for high-speed finishing of aluminum, non-ferrous alloys, and graphite electrodes.
05
Primary users include medical device manufacturers (implants, instruments), aerospace tier suppliers (brackets, fittings), watch and optical industry manufacturers, and precision electronics producers. Its compact size and automation-readiness also make it popular for contract shops running mixed-material production.
