Machine Comparison
DMG Mori SPRINT 32|8 vs DMG Mori SPRINT 42 linear
DMG Mori vs DMG Mori · Swiss-Type Lathes
Summary
The DMG Mori SPRINT 32|8 and SPRINT 42 linear are neighboring Swiss-type lathes in the same range. They share 8,500 RPM main and sub-spindles, 6 linear axes plus 2 C-axes and the Fanuc 32i control. The difference is size.
The SPRINT 42 linear takes 42 mm (1.7 in) bar against 32 mm (1.3 in), and handles workpieces up to 320 mm (12.6 in) long against 240 mm (9.4 in). Beyond bar and part size, the table shows the two machines on equal terms, so the decision rests on the diameter and length of the parts a shop runs. Both target medical, dental, automotive fuel-system and aerospace hydraulic work.

Advantages
DMG Mori SPRINT 32|8
- Sized for bone screws, dental abutments and injector bodies up to 32 mm (1.3 in) bar
- The smaller of the two machines for shops whose work stays under 32 mm
DMG Mori SPRINT 42 linear
- 42 mm (1.7 in) bar capacity against 32 mm (1.3 in)
- 320 mm (12.6 in) maximum workpiece length against 240 mm (9.4 in)
Verdict
Buy the SPRINT 42 linear when parts fall in the 33-42 mm range or run longer than 240 mm, such as larger orthopedic screws, spinal rods, common rail parts and hydraulic valve bodies. Buy the SPRINT 32|8 when work stays at or below 32 mm, since the two machines are otherwise listed with the same 8,500 RPM spindles, axis layout and control.
