Overview

The DMG Mori SPRINT 50|5 is a high-performance automatic Swiss-type lathe (also known as a sliding headstock lathe) designed for the complete machining of complex, precision bar stock components up to 50 mm in diameter. With 5-axis machining capability and a compact multi-spindle tooling arrangement, it is engineered for the medical, automotive, hydraulic, and electronics industries where small, geometrically complex parts must be produced with sub-micron repeatability at high throughput.

The SPRINT 50|5 incorporates a main spindle and counter spindle, enabling complete front and back machining of components — including milling, drilling, threading, and polygon turning — in a continuous automated cycle without operator intervention. The machine's guide bushing system supports the bar stock adjacent to the cutting zone, dramatically reducing deflection and enabling slender parts to be machined with exceptional roundness and surface finish even at large length-to-diameter ratios.

With 5 CNC axes and the ability to run up to 11 tools simultaneously (depending on configuration), the SPRINT 50|5 minimizes cycle time by overlapping machining operations on the main and counter spindles. A powerful bar feeder interface and automatic part catching system enable fully unattended production runs of thousands of parts per shift, which is critical for competitive pricing in high-volume precision component supply chains.

The SPRINT 50|5 runs on a Siemens SINUMERIK 840D sl control with DMG Mori's CELOS interface, providing full program management, process visualization, and connectivity to higher-level MES/ERP systems. Its compact footprint makes it practical even for shops with limited floor space, and its modular tooling system allows quick changeover between part families.

Strengths & Limitations

Strengths

50 mm maximum bar capacity is among the largest in the Swiss-type category, enabling a wide range of part sizes
5-axis capability with simultaneous multi-spindle operation minimizes cycle time on complex parts
Guide bushing system enables slender-part machining with excellent roundness and surface finish
Compact footprint relative to its capability makes efficient use of shop floor space
Full integration with bar feeder and parts catcher enables truly unattended high-volume production

Limitations

Higher complexity compared to standard fixed-headstock lathes requires experienced Swiss-type operators and programmers
Guide bushing requires consistent bar stock tolerances — poor bar stock quality leads to chatter and finish issues
High initial investment cost; ROI depends on sustained high-volume precision part production

Best For

Medical device manufacturers producing implant screws, bone anchors, cannulas, and surgical instruments from titanium and stainless Automotive suppliers producing fuel injector components, ABS sensor rings, and precision hydraulic fittings Electronics and connector manufacturers machining complex small-diameter contact pins and housings Hydraulic component manufacturers producing valve spools, fittings, and precision cylinders

Frequently Asked Questions

01 What does the '5' in SPRINT 50|5 refer to?

The '5' refers to the machine's 5-axis CNC capability. This enables simultaneous multi-axis interpolation for complex contoured features on small-diameter parts, going well beyond simple turning and drilling to include helical milling, polygon turning, and off-center features — all within a single cycle.

02 Does the SPRINT 50|5 require a guide bushing, and can it run without one?

The guide bushing is standard and is the primary method for achieving the high accuracy and surface finish Swiss-type lathes are known for on slender parts. Some Swiss-type machines can be reconfigured to run without a guide bushing (guide bushingless mode) for shorter parts, which reduces bar remnant waste. DMG Mori can advise on whether bushingless operation is supported for specific SPRINT 50|5 configurations.

03 What is the maximum part length the SPRINT 50|5 can machine in a single cycle?

The SPRINT 50|5 can machine parts up to approximately 200 mm in length from the main spindle in a single cycle. Longer parts may require two-operation machining or alternative fixturing strategies. The counter spindle handles backworking features on the rear face of each part automatically.

04 What bar stock quality is required for the SPRINT 50|5?

For best results, bar stock should meet h9 or better dimensional tolerance and have good straightness. Poor bar straightness or inconsistent diameter causes vibration in the guide bushing, leading to poor surface finish, premature bushing wear, and dimensional variation. Centerless-ground bar stock is ideal for demanding applications.

05 Is the SPRINT 50|5 suitable for machining medical titanium parts?

Yes. The SPRINT 50|5 is widely used in medical device manufacturing for bone screws, dental implants, and surgical instruments from Grade 5 titanium (Ti-6Al-4V) and medical-grade stainless steel. Its high-speed spindle, rigid guide bushing support, and through-tool high-pressure coolant capability make it well suited for these demanding applications.
