Overview

The DMG Mori SPRINT 50 is a turret-based automatic lathe designed for high-productivity bar machining of workpieces up to 52.5 mm diameter, with an optional 90 mm chuck work capability. Unlike the smaller SPRINT models that use Swiss-type guide bush technology, the SPRINT 50 uses VDI turrets in a vertical machine bed layout, bridging the gap between Swiss-type automatic lathes and conventional CNC turning centers.

The main and counter spindle both deliver 7,000 RPM with 16 kW (21.5 HP) of power. Driven tool spindles run at 8,000 RPM with 1.5 kW (2 HP) and 10 Nm, handling cross-drilling, milling, and tapping operations. The machine comes in multiple turret configurations: 2-turret TWIN design or 3-turret version, with an optional B-axis on the lower turret that swivels from -23.5 to +158.5 degrees.

Each turret holds 12 VDI 25 tool stations with Trifix quick-change interface, and every station can be driven. With three turrets, that gives you 36 driven tool positions for complex done-in-one machining. Y-axis is available on every turret for off-center work.

The vertical bed design minimizes the floor footprint while the slant-bed chip flow keeps the workspace clean. Simultaneous machining on both spindles with multiple turrets means the SPRINT 50 can match the throughput of much larger machines on parts that fit within its 52.5 mm bar envelope.

The SPRINT 50 competes with the Index ABC and Citizen Miyano BNE-51 in the medium-bar automatic lathe category. Its B-axis turret option and Trifix quick-change tooling are key differentiators. Available with either Siemens or Fanuc control with MAPPS V. Specs sourced from DMG Mori published data and industry specifications.

Strengths & Limitations

Strengths

Up to three turrets with 36 total driven tool positions provide massive flexibility for complex multi-operation parts in one setup
B-axis on lower turret with -23.5 to +158.5 degree swivel enables compound-angle machining with standard tools, reducing tooling costs
Trifix quick-change tooling on all stations cuts changeover time significantly compared to conventional VDI setups
7,000 RPM twin spindles with 21.5 HP each handle aggressive material removal on both main and counter operations simultaneously
Vertical bed design provides excellent chip evacuation and compact footprint compared to horizontal bed alternatives
Y-axis on every turret means off-center features can be machined from any turret position without limitations
Choice of Siemens or Fanuc control lets shops match the machine to their existing operator skill base

Limitations

Driven tool power at 1.5 kW (2 HP) is limited for heavy milling operations; serious secondary milling work may still need a VMC
Starting around $300K for a 2-turret setup and exceeding $450K for 3 turrets with B-axis, the investment is significant
52.5 mm max bar capacity is between Swiss-type and conventional lathes, which can make it a niche fit for some shops
Three-turret programming complexity requires operators with multi-channel turning experience or offline CAM capability

Best For

Production shops running 40-52 mm bar stock that need done-in-one capability with milling, drilling, and angular features Hydraulic fitting and valve manufacturers machining complex parts from stainless and brass bar stock Automotive drivetrain component producers needing high-volume automatic bar machining with multi-turret productivity Medical device manufacturers producing larger implant components and instrument handles that exceed Swiss-type capacity Aerospace fastener and fitting manufacturers needing B-axis compound-angle capability on bar work

Frequently Asked Questions

01 What does a new DMG Mori SPRINT 50 cost?

New pricing runs $300,000-$500,000 depending on configuration. A 2-turret TWIN setup starts lower, while the 3-turret version with B-axis and full automation pushes toward the higher end. The B-axis option adds roughly $50,000-$80,000 to the base configuration.

02 Is the SPRINT 50 a Swiss-type machine?

No. Unlike the smaller SPRINT 20, 32, and 42 models that use guide bush Swiss-type technology, the SPRINT 50 is a turret-based automatic lathe without a guide bush. It uses VDI turrets in a vertical bed configuration. For Swiss-type work at larger diameters, consult DMG Mori about specific applications.

03 What is the B-axis on the SPRINT 50?

The optional B-axis on the lower turret lets you swivel the entire turret from -23.5 to +158.5 degrees. This enables machining features at compound angles using standard tools rather than special angular toolholders. It is particularly useful for angled holes, chamfers, and contoured features.

04 How does the SPRINT 50 compare to the Index ABC?

Both are multi-turret automatic lathes in the 50 mm bar class. The Index ABC has a proven track record in the automatic lathe market. The SPRINT 50 offers the B-axis option and Trifix quick-change tooling. Performance is comparable; the choice typically comes down to local support and operator familiarity with the control platform.
