DMG Mori SPRINT 20|5 vs DMG Mori SPRINT 32|8
DMG Mori vs DMG Mori · Swiss-Type Lathes
Summary
The DMG Mori SPRINT 20|5 and the DMG Mori SPRINT 32|8 are Swiss-type lathes from the same family, each with a main and a counter spindle and a FANUC 32i-series control. The headline difference is bar size: the DMG Mori SPRINT 20|5 takes bar up to 20 mm (0.8 in), the DMG Mori SPRINT 32|8 up to 32 mm (1.3 in).
The DMG Mori SPRINT 32|8 is the stronger machine: 7.4 hp and 29.8 ft lb at the main spindle against a nominal 3 hp and 10.3 ft lb, a total of 41 tool stations against 23, and a maximum workpiece length of 240 mm (9.4 in) against 180 mm (7.1 in). The DMG Mori SPRINT 20|5 is the faster one, with 10,000 rpm on both the main and the counter spindle against 8,500 rpm.

Advantages
DMG Mori SPRINT 20|5
- 10,000 rpm on the main and counter spindle against 8,500 rpm on the DMG Mori SPRINT 32|8
- Sized for small work: bar up to 20 mm (0.8 in), where the higher spindle speed keeps cutting speed up on small diameters
DMG Mori SPRINT 32|8
- Bar capacity of 32 mm (1.3 in) against 20 mm (0.8 in)
- 7.4 hp and 29.8 ft lb at the main spindle against a nominal 3 hp and 10.3 ft lb
- Total of 41 tool stations against 23
- Maximum workpiece length of 240 mm (9.4 in) against 180 mm (7.1 in)
Verdict
Choose by bar diameter. The DMG Mori SPRINT 20|5 fits shops whose parts stay within 20 mm (0.8 in) of bar and 180 mm (7.1 in) of length and that want 10,000 rpm on both spindles for small diameters. The DMG Mori SPRINT 32|8 is the one for larger or tougher parts: it takes 32 mm (1.3 in) bar, has more than twice the main spindle power and torque, and carries 41 tool stations for parts with many operations.
