Overview
The Chiron FZ 18W is a single-spindle, 5-axis machining center with an integrated workpiece changer, built on Chiron's 18 Series platform. The "W" designation marks the inclusion of automated pallet exchange, enabling the operator to load and unload parts outside the machining zone while the spindle cuts. Chiron highlights this machine for "flexible machining" applications including automotive wheel machining in sizes from 16 to 24 inches, demonstrating the versatility of the larger 18 Series work envelope.
With X/Y/Z travels of 730 x 560 x 500 mm (28.7 x 22.0 x 19.7 in), the FZ 18W handles medium-size parts that exceed the capacity of the 15 and 16 Series. The integrated workpiece changer swings pallets into the machining zone with minimal changeover time, pushing spindle utilization above 90% in production settings. The machine features linear direct drives on all linear axes, direct-drive A and C rotary axes, and a mineral-cast bed for vibration damping and thermal stability.
Spindle options include the HSK-A63 at 20,000 RPM for high-speed aluminum work and the HSK-A100 with 400 Nm of torque for steel and titanium. The basket-type tool changer accommodates up to 60 tools with fast chip-to-chip times. Workpiece capacity reaches 800 mm diameter and 400 kg per pallet position, making the FZ 18W capable of handling larger automotive and aerospace parts.
New FZ 18W machines price between $475,000 and $650,000, with the workpiece changer adding roughly $40,000-$60,000 over the fixed-table FZ 18S. The machine competes with the Hermle C 400 with handling system, DMG Mori DMU 80 P with pallet changer, and the Chiron DZ 18W for shops that need twin-spindle production. Used units from 2017-2023 trade between $250,000 and $450,000.
The FZ 18W's unique strength is combining a production-oriented workpiece changer with a work envelope large enough for parts like automotive wheels, medium structural components, and larger medical devices — applications where smaller pallet-changer machines fall short on envelope and larger machines are overkill.

Strengths & Limitations
Strengths
- Integrated workpiece changer pushes spindle utilization above 90% by enabling load/unload during machining
- 730 mm X-travel handles medium-size parts including automotive wheels (16-24 inch) that smaller pallet machines cannot accommodate
- Linear direct drives on all linear axes provide zero-backlash dynamics superior to ball-screw systems
- HSK-A100 high-torque option with 400 Nm enables steel and titanium cutting alongside high-speed aluminum work
- Mineral-cast bed and water-cooled drives deliver thermal stability for tight-tolerance production across extended runs
- Single-spindle flexibility allows different parts on each pallet, unlike twin-spindle DZ variants
Limitations
- Two-pallet system provides limited buffer for extended unmanned operation — additional automation needed for lights-out
- Up to 60 tools is modest compared to competitors offering 100+ tool magazines in this size class
- Larger footprint than 15/16 Series reduces the floor-space advantage of Chiron's compact design
- Starting price around $475,000 competes directly with well-supported platforms from Hermle and DMG Mori
- Chiron's North American service network remains smaller than established competitors

Frequently Asked Questions
01
New FZ 18W machines start around $475,000 and can reach $650,000 with the HSK-A100 torque spindle, expanded tool magazine, high-pressure coolant, and probing. The workpiece changer adds roughly $40,000-$60,000 over the comparable FZ 18S. Used units from 2017-2023 trade between $250,000 and $450,000.
02
Yes. Chiron specifically positions the FZ 18W for flexible machining of wheels in sizes 16 to 24 inches. The 800 mm workpiece diameter capacity and 400 kg weight limit accommodate standard aluminum alloy wheels. The workpiece changer enables continuous production with minimal downtime between wheel blanks.
03
The DZ 18W adds a second spindle for twin-spindle production of identical parts. The FZ 18W is single-spindle, offering more flexibility to run different parts on each pallet. Choose the DZ 18W for high-volume identical parts; the FZ 18W when you need pallet automation with part-mix flexibility.
04
The FZ 18W adds an integrated workpiece changer that eliminates load/unload downtime from the cycle. This pushes spindle utilization above 90% versus roughly 70-80% for the fixed-table FZ 18S. On parts with cycle times under 15 minutes, the FZ 18W can produce 10-20% more parts per shift.
05
Yes. Chiron offers automation packages that connect robot loaders to the workpiece changer for extended unmanned operation. The two-pallet integrated changer provides the interface point, and the robot handles blank and finished part logistics. This is typically specified at time of order for optimal integration.
