Overview
The DMG Mori SPRINT 42|10 linear is the top-specification Swiss-type automatic lathe in the 42 mm SPRINT family, combining linear motor drives with 8 linear axes, 2 C-axes, and up to 30 total tool stations including 22 driven positions. This machine represents the pinnacle of 42 mm Swiss-type capability with 1G acceleration on the X1 and X3 axes.
The main spindle delivers 6,500 RPM with 37.5 Nm (27.7 ft-lb) of torque and 5.5 kW (7.4 HP) of power. The counter spindle matches at 6,500 RPM with 19.6 Nm (14.5 ft-lb) and 3.7 kW (5 HP). Driven tool stations run at 5,000 RPM with 2.2 Nm (1.6 ft-lb) and 0.5 kW (0.7 HP). Maximum bar diameter is 42 mm (1.65 in) with parts up to 320 mm (12.6 in) long.
The linear motor drives on X1 and X3 axes eliminate backlash entirely, which directly translates to better surface finish and tighter dimensional accuracy on finishing passes. The 1G acceleration capability reduces non-cutting time during rapid movements and tool changes. These advantages are most pronounced on high-volume production runs where fractions of a second per cycle add up to significant throughput gains.
Travel ranges include 50 mm on X, 350 mm on Y, and 120 mm on Z. The turret carries 16 stations within the total 30-station capacity, and up to 3 tools can work simultaneously across the main and counter spindle. The Fanuc 310i control with 3 channels drives the multi-axis coordination on a 15-inch SLIM_line display.
With up to 22 driven tools and 3 simultaneous cutting paths, the SPRINT 42|10 linear handles the most demanding 42 mm Swiss-type applications. Medical implant bodies, larger orthopedic screws, automotive common rail components, and aerospace structural fittings with complex milled features are its primary domain.

Strengths & Limitations
Strengths
- Linear motor drives on X1 and X3 deliver 1G acceleration for faster cycle times and superior surface finish with zero backlash
- Up to 22 driven tool positions provide extensive milling and drilling capability for complex done-in-one parts
- 3 simultaneous cutting paths across main and counter spindle maximize metal removal and minimize cycle time
- 42 mm bar capacity fills the gap between 32 mm Swiss-type and conventional lathes for medium-diameter precision parts
- Fanuc 310i control with 3 channels provides the computational power to coordinate 10 axes smoothly in production
- 30 total tool stations with 16-station turret reduce setup time when running parts with many different features
Limitations
- Linear drive technology and 10-axis configuration push the price to $320K-$480K, significantly above ballscrew alternatives
- Programming complexity with 3 channels and 10 axes requires specialized CAM software and experienced Swiss-type programmers
- Driven tool power at only 0.5 kW limits aggressive milling in harder materials like titanium and Inconel
- Higher power consumption from linear motors compared to ballscrew drives increases operating costs over machine lifetime

Frequently Asked Questions
01
New pricing runs $320,000-$480,000 depending on configuration and tooling package. The linear drive platform and 10-axis capability command a premium over the standard SPRINT 42 linear. Additional driven tool stations, high-pressure coolant, and automation integration push toward the higher end.
02
The SPRINT 42|10 linear upgrades to 8 linear axes (vs 6), up to 22 driven tools (vs 8), 3 simultaneous cutting paths (vs 2), and a Fanuc 310i control with 3 channels. It also has 30 total tool stations vs 26. The 42|10 is the higher-capability variant for more complex parts.
03
The 6,500 RPM main spindle (vs 8,500 on 32 mm models) reflects the larger bar diameter. Surface speed is actually higher at 42 mm diameter at 6,500 RPM than at 32 mm at 8,500 RPM. The 37.5 Nm torque provides the power needed for aggressive cutting on the larger stock.
04
LNS, IEMCA, and FMB all make bar feeders compatible with 42 mm Swiss-type machines. The LNS Express 342 and IEMCA Elite 542 are common pairings. Confirm bar length capacity and magazine loading with your bar feeder supplier to match your production requirements.
