Overview

The DMG Mori SPRINT 42 linear is a high-performance Swiss-type automatic lathe with linear motor drives that handles bar stock up to 42 mm diameter. The linear drive technology delivers up to 1G acceleration on the X1 axis, providing exceptional dynamic response for faster cycle times and better surface finishes compared to ballscrew-driven alternatives.

The main spindle runs at 8,500 RPM with 7.5 kW (10.1 HP) at 30-minute rating and 5.5 kW continuous. Both the main and counter spindle use direct drive technology for consistent speed control and reduced vibration. Maximum cutting length is 320 mm, and the 6-axis configuration handles complex parts with simultaneous main and counter spindle machining.

The 42 mm bar capacity fills an important gap in the Swiss-type market. Parts too large for 32 mm machines but too small for conventional lathes land squarely in the SPRINT 42's wheelhouse. Think medical implant bodies, larger orthopedic screws, automotive common rail components, and aerospace structural fittings. At 42 mm, you are also covering many hydraulic fitting and valve component applications.

Linear motor drives on the primary axes eliminate backlash entirely, which matters on finishing passes where surface finish and dimensional accuracy are critical. The drives also reduce maintenance since there are no ballscrews to wear. The tradeoff is higher initial cost and potentially higher power consumption.

The machine supports up to 26 tools total with 8 driven positions, giving you extensive milling, drilling, and tapping capability. The counter spindle handles backworking for complete parts in one setup.

The SPRINT 42 linear competes with the Citizen Cincom M32, Star SR-38, and Tsugami TMA42 in the larger Swiss-type segment. Its linear drives are the key differentiator. Specs sourced from DMG Mori published data and industry specifications.

Strengths & Limitations

Strengths

Linear motor drives deliver up to 1G acceleration on X1 axis for faster cycle times and superior surface finish compared to ballscrew machines
42 mm bar capacity fills the gap between 32 mm Swiss-type and conventional lathes for medium-diameter precision parts
Direct drive spindles on both main and counter positions eliminate gear and belt vibration for better concentricity and finish
Up to 26 tool stations with 8 driven positions provide extensive milling and drilling capability for complex done-in-one parts
Zero backlash from linear drives means tighter tolerances on finishing passes without compensation adjustments
8,500 RPM on both spindles provides speed for aluminum and brass finishing while maintaining power for steel and stainless roughing

Limitations

Linear drive technology adds significant cost premium over ballscrew alternatives, starting around $280K new
42 mm Swiss-type programming requires specialized knowledge; the larger bar size adds complexity to guide bush setup and tool reach calculations
Higher power consumption from linear motors compared to ballscrew drives increases operating costs over the machine lifetime
Limited used market availability compared to more common 20 mm and 32 mm Swiss-type machines

Best For

Medical implant manufacturers producing larger orthopedic screws, spinal rods, and implant bodies in titanium and cobalt chrome Automotive common rail and fuel system component producers needing Swiss-type precision on 35-42 mm diameter parts Aerospace hydraulic fitting and actuator component manufacturers running stainless and titanium bar stock Dental implant companies producing abutments and fixtures that exceed 32 mm Swiss-type capacity Precision hydraulic valve and fitting manufacturers machining complex geometries from stainless and brass bar Any shop running parts in the 33-42 mm range that need Swiss-type rigidity and done-in-one capability

Frequently Asked Questions

01 What does a new DMG Mori SPRINT 42 linear cost?

New pricing runs $280,000-$420,000 depending on configuration. The linear drive technology adds a premium over ballscrew alternatives. Additional driven tool stations, high-pressure coolant, and automation integration push toward the higher end. Used units are less common than smaller SPRINT models.

02 What are linear motor drives and why do they matter?

Linear motors drive the axis slides directly without ballscrews, gears, or belts. This eliminates backlash and mechanical wear while providing up to 1G acceleration. The result is better surface finish, tighter tolerances, and faster cycle times. The tradeoff is higher initial cost and power consumption.

03 How does the SPRINT 42 linear compare to the SPRINT 42|10 linear?

The SPRINT 42|10 linear is an updated variant with 10 driven tool stations versus 8 on the standard SPRINT 42 linear. The additional driven stations provide more flexibility for complex parts. Both share the linear drive platform and 42 mm bar capacity.

04 Can the SPRINT 42 linear run without the guide bush?

Some Swiss-type machines offer guide-bush-less operation for shorter parts. Consult DMG Mori for your specific application. Running without the guide bush changes the machine dynamics and may affect tolerance capability on longer parts. For short chucked parts, a conventional CNC lathe may be more cost-effective.

05 What bar feeder works with the SPRINT 42 linear?

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.
