DMG Mori SPRINT 20|5 vs Tornos DECO 20a
DMG Mori vs Tornos · Swiss-Type Lathes
Summary
The DMG Mori SPRINT 20|5 and the Tornos DECO 20a are Swiss-type lathes for the same bar size: 20 mm (0.8 in) on the DMG Mori SPRINT 20|5 and 20.5 mm (0.807 in) on the Tornos DECO 20a. Both run the main spindle and the counter spindle to 10,000 rpm. The differences are in spindle power, axis count and control.
The Tornos DECO 20a has the stronger main spindle, 5.5 kW (7.4 hp) against a nominal 3 hp, and is listed with up to 10 axes against 5 linear axes and up to 2 C-axes. The DMG Mori SPRINT 20|5 runs a FANUC 32i control with 2 control channels; the Tornos DECO 20a is programmed through Tornos TB-DECO / TISIS.
Specifications Comparison
| Specification | DMG Mori SPRINT 20|5 | Tornos DECO 20a |
|---|---|---|
| Bar Capacity | 20 mm (0.8 in) | 20.5 mm (0.807 in) ▲ |
| Max Spindle Speed | 10,000 rpm (main spindle) | 10,000 RPM |
| Spindle Power | 3 hp (main spindle, nominal) | 5.5 kW (7.4 hp) ▲ |
| Sub-Spindle Speed | 10,000 rpm (counter spindle) | 10,000 RPM |
| Axes | 5 linear axes and up to 2 C-axes | Up to 10 |
| Control | FANUC 32i with 10.4" color display; 2 control channels | Tornos TB-DECO / TISIS |
Advantages
DMG Mori SPRINT 20|5
- FANUC 32i control with 2 control channels, against the Tornos TB-DECO / TISIS programming system
- A simpler axis layout, 5 linear axes and up to 2 C-axes, for parts that do not need up to 10 axes
Tornos DECO 20a
- 5.5 kW (7.4 hp) main spindle against a nominal 3 hp
- Up to 10 axes against 5 linear axes and up to 2 C-axes
- Slightly larger bar capacity, 20.5 mm (0.807 in) against 20 mm (0.8 in)
Verdict
With bar size and spindle speed equal, the choice comes down to part complexity and control. The Tornos DECO 20a suits complex medical, watch and aerospace parts that use its up to 10 axes and 5.5 kW (7.4 hp) main spindle, in shops prepared to work in TB-DECO or TISIS. The DMG Mori SPRINT 20|5 suits simpler turned parts with light cross drilling and milling, and shops that want a FANUC 32i control.
