DMG Mori CMX 50 U vs Hurco BX40Ui
DMG Mori vs Hurco · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and the Hurco BX40Ui are both 5-axis machining centers, but they sit in different size classes. The Hurco is a bridge-style machine with 950 mm (37.4 in) of X travel against 500 mm (19.7 in), 550 mm (21.65 in) of Y and 500 mm (19.68 in) of Z against 450 mm and 400 mm, and a 250 kg (550 lb) table against 200 kg (440.9 lb).
The BX40Ui also leads on the spindle: 20,000 rpm against 12,000 RPM, 35 kW (47 hp) against 22 kW (30 hp) and 118.9 Nm (87.7 ft-lb) against 86 Nm (63 ft-lb), on an HSK-63A taper. Its tool change takes 1.5 sec against 3.0 sec, with 30 tools on both. The CMX 50 U is the smaller machine at 6,600 kg (14,551 lb) against 9,400 kg (20,723 lb), with Fanuc or Siemens under CELOS where the Hurco runs WinMax.

Advantages
DMG Mori CMX 50 U
- Smaller machine at 6,600 kg (14,551 lb) against 9,400 kg (20,723 lb)
- Choice of Fanuc 31i-B5 or Siemens 840D sl under CELOS
- CAT 40 / BBT 40 taper rather than HSK-63A
Hurco BX40Ui
- 950 mm (37.4 in) of X travel against 500 mm (19.7 in)
- 20,000 rpm and 35 kW (47 hp) against 12,000 RPM and 22 kW (30 hp)
- 118.9 Nm (87.7 ft-lb) of torque against 86 Nm (63 ft-lb)
- 1.5 sec tool change against 3.0 sec
Verdict
The Hurco BX40Ui suits high-speed aluminum work, aerospace structural parts, mold contouring in hardened steel and titanium implants, where 950 mm of X travel, 20,000 rpm and 35 kW pay off. The CMX 50 U suits smaller parts within 500 x 450 x 400 mm, first 5-axis installations and training, especially in shops standardized on Fanuc or Siemens controls.
