Machine Comparison
Chiron DZ 12S vs Chiron DZ 12W
Chiron vs Chiron · Vertical Machining Centers
Summary
The Chiron DZ 12S and Chiron DZ 12W are two versions of the same Chiron twin-spindle vertical machining center, and their spec tables are identical. Both have 550 x 400 x 400 mm of travel, 15,000 - 24,000 rpm spindles with 29 - 59 Nm of torque, HSK-A50 / HSK-A63 tooling, 2 x 12 - 2 x 104 tools, a 3.1 sec chip-to-chip time and 75 m/min rapids on a Siemens SINUMERIK 840D sl control.
The difference is in how parts reach the spindles. The DZ 12W is the workpiece-changer version, aimed at shops running very high volumes of identical parts that want loading to overlap with cutting. The DZ 12S is the standard version for twin-spindle production where that extra automation is not needed.
Specifications Comparison
| Specification | Chiron DZ 12S | Chiron DZ 12W |
|---|---|---|
| X-Axis Travel | 550 mm | 550 mm |
| Y-Axis Travel | 400 mm | 400 mm |
| Z-Axis Travel | 400 mm | 400 mm |
| Max Spindle Speed | 15,000 – 24,000 rpm | 15,000 – 24,000 rpm |
| Spindle Torque | 29 – 59 Nm | 29 – 59 Nm |
| Spindle Taper / Nose | HSK-A50 / HSK-A63 | HSK-A50 / HSK-A63 |
| Tool Capacity | 2 x 12 – 2 x 104 | 2 x 12 – 2 x 104 |
| Chip-to-Chip Time | 3.1 s | 3.1 s |
| Rapid Traverse | 75 – 75 – 75 m/min (X – Y – Z) | 75 – 75 – 75 m/min (X – Y – Z) |
Advantages
Chiron DZ 12S
- Standard twin-spindle layout without the workpiece changer, for cells that do not need it
- Suits contract manufacturers and shops replacing transfer lines at moderate high volumes
Chiron DZ 12W
- Workpiece changer version, aimed at keeping both spindles cutting while parts are loaded
- Aimed at the highest-volume small-part programs where cost per piece decides the job
- Adds throughput for shops already running DZ 12S machines without more floor space
Verdict
On the published specs the two are the same machine, so the choice is about automation. Choose the Chiron DZ 12W for very high-volume programs of identical small parts where the workpiece changer keeps the spindles busy and pays back through cost per piece. Choose the Chiron DZ 12S when volumes are lower or parts change more often and the standard twin-spindle layout is enough.
