Machine Comparison
DMG Mori SPRINT 20|5 vs INDEX C100
DMG Mori vs INDEX-Traub · Swiss-Type Lathes
Summary
The DMG Mori SPRINT 20|5 and the INDEX C100 both turn parts from bar, but they are built for different jobs. The DMG Mori SPRINT 20|5 is a small Swiss-type lathe for bar up to 20 mm (0.8 in). The INDEX C100 is a production turning machine for bar up to 42 mm (1.7 in), with a main spindle rated 25 / 29 kW against a nominal 3 hp.
The INDEX C100 leads on cutting capacity, with 49 / 65 Nm of spindle torque against 10.3 ft lb. The DMG Mori SPRINT 20|5 leads on speed, with 10,000 rpm on both the main and the counter spindle against 7,000 rpm. Tooling is counted differently: 23 tool stations in total on the DMG Mori SPRINT 20|5, and VDI20 or VDI25 turret stations on the INDEX C100, which is offered with a Siemens S840D sl or a FANUC 31i-B control.

Advantages
DMG Mori SPRINT 20|5
- 10,000 rpm on the main and counter spindle against 7,000 rpm
- Sized for small parts: bar up to 20 mm (0.8 in), where spindle speed matters more than power
INDEX C100
- Bar capacity of 42 mm (1.7 in) against 20 mm (0.8 in)
- Main spindle rated 25 / 29 kW against a nominal 3 hp
- 49 / 65 Nm of spindle torque against 10.3 ft lb
- Offered with a Siemens S840D sl or a FANUC 31i-B control
Verdict
These machines suit different work. Choose the DMG Mori SPRINT 20|5 for small turned parts from bar up to 20 mm (0.8 in) that need front and back machining at 10,000 rpm. Choose the INDEX C100 for high-volume production of larger and more complex parts up to 42 mm (1.7 in), where its 25 / 29 kW spindle and multi-turret layout cut cycle time. A shop whose parts fit the smaller machine would not use the capacity of the larger one.
