Machine Comparison
DMG Mori CMX 50 U vs DMG Mori ULTRASONIC 85
DMG Mori vs DMG Mori · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and ULTRASONIC 85 are both 5-axis machining centers, but they serve different jobs. The CMX 50 U is a compact general-purpose machine for metal parts; the ULTRASONIC 85 is a larger machine with an HSK-A63 spindle and ultrasonic actuator, aimed at ceramics, CMCs and other hard, brittle materials.
The ULTRASONIC 85 travels 935 x 850 x 650 mm against 500 x 450 x 400 mm, takes 1,500 kg (3,306.9 lb) on the table against 200 kg (440.9 lb), spins up to 30,000 RPM against 12,000 RPM, and holds up to 180 tools against 30 as standard. The CMX 50 U uses a CAT 40 / BBT 40 spindle and offers Fanuc 31i-B5 or Siemens 840D sl under CELOS.

Advantages
DMG Mori CMX 50 U
- CAT 40 / BBT 40 spindle for conventional steel and aluminum milling
- Choice of Fanuc 31i-B5 or Siemens 840D sl under CELOS
- Compact 500 x 450 x 400 mm envelope sized for small fittings, prototypes and medical parts
DMG Mori ULTRASONIC 85
- 935 x 850 x 650 mm of travel against 500 x 450 x 400 mm
- 1,500 kg (3,306.9 lb) table load against 200 kg (440.9 lb)
- Up to 30,000 RPM with an ultrasonic HSK-A63 spindle against 12,000 RPM
- Up to 180 tools against 30 standard
Verdict
Buy the ULTRASONIC 85 if the work is in ceramics, CMCs or similar hard and brittle materials, especially large parts of them; its ultrasonic HSK-A63 spindle, 30,000 RPM and 1,500 kg table are built around that. For general 5-axis metal parts within 500 x 450 x 400 mm, such as medical components, aerospace fittings and mold parts, the CMX 50 U is the fit.
