Overview
The DMG Mori SPRINT 20|8 is a high-performance Swiss-type automatic lathe with 8 axes for maximum simultaneous machining capability on parts up to 20 mm bar diameter. It steps up from the SPRINT 20|5 with additional axes and tooling capacity, targeting shops that need complex multi-operation parts completed in a single bar feed cycle.
The machine features 6 linear axes and 2 C-axes, with both main and counter spindles running at 10,000 RPM. X-axis travel is 50 mm (2.0 in), Z-axis travel is 60 mm (2.4 in), and Y-axis travel is a generous 325 mm (12.8 in). Eight driven tool stations come as standard, with a total of 25 tool stations available for complex multi-operation parts.
Driven tool spindles run at 6,000 RPM for milling, drilling, and tapping operations. The 8-axis configuration enables simultaneous cutting on both main and counter spindle, plus cross-working operations — all happening concurrently. This parallel processing capability is what sets the 20|8 apart from the 5-axis 20|5 model and directly reduces cycle time on complex parts.
The guide bush supports the bar near the cutting zone, providing the rigidity needed to machine long, slender parts without deflection. The entire machine fits in a footprint of under 2 m2, making it one of the most capability-dense CNC machines available per square foot. Control is FANUC 32i with a 10.4-inch color display.
New SPRINT 20|8 machines price between $250,000 and $380,000. The SPRINT 20|8 competes with the Citizen Cincom L20XII, Star SR-20JII, and Tsugami SS20 in the 20mm high-performance Swiss-type category. Specs sourced from DMG Mori published data.

Strengths & Limitations
Strengths
- 8-axis configuration enables simultaneous main spindle, counter spindle, and cross-working operations for maximum productivity
- 10,000 RPM on both main and counter spindles delivers excellent surface finish and speed on small-diameter precision parts
- 325 mm Y-axis travel is exceptionally generous for a Swiss-type, enabling complex off-center milling operations
- 25 total tool stations provide enough capacity for complex multi-operation parts without mid-run tool changes
- Sub-2 m2 footprint packs 8-axis capability into the smallest possible floor space
- FANUC 32i control with multi-channel programming enables efficient simultaneous operations across all axes
Limitations
- 20 mm bar capacity limits the machine to very small parts — anything larger requires the SPRINT 32|8 or SPRINT 42
- At $250,000-$380,000, it costs $70K-$100K more than the SPRINT 20|5, which may not be justified on simpler parts
- 8-axis Swiss-type programming requires specialized knowledge and multi-channel experience that most operators lack
- More axes and tooling positions mean more setup complexity and longer changeover times on new jobs

Frequently Asked Questions
01
New pricing runs $250,000-$380,000 depending on options. The 8-axis configuration costs significantly more than the 5-axis SPRINT 20|5 ($180,000-$280,000). Adding high-pressure coolant, oil mist collection, and bar feeder integration pushes toward the top of the range.
02
The 20|8 justifies its premium when your parts have multiple features that benefit from simultaneous machining. If you can cut on the main spindle, counter spindle, and cross-work position all at the same time, the 8-axis machine will deliver shorter cycle times. For simpler parts with sequential operations, the 20|5 is more cost-effective.
03
Both are 20 mm Swiss-type machines with 8+ axis capability. The Citizen L20XII has a longer track record in Swiss-type and offers the LFV (Low Frequency Vibration) chip breaking technology. The SPRINT 20|8 benefits from DMG Mori's service network and 325 mm Y-axis travel. Performance is comparable; choose based on your operator experience and dealer support.
04
325 mm is exceptionally generous for a Swiss-type machine. It enables complex off-center milling operations including deep pocketing, contouring, and hexagonal machining that would be impossible on machines with typical 40-50 mm Y-travel. This is particularly valuable for medical and aerospace parts with complex milled features.
