DMG Mori CMX 50 U vs Willemin-Macodel 701S
DMG Mori vs Willemin-Macodel · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and the Willemin-Macodel 701S are both 5-axis machining centers, but they serve different jobs. The Willemin-Macodel 701S is a micro-machining center with 200 x 150 x 250 mm of travel and a 36,000 rpm spindle, aimed at watch, dental, medical and electronics micro-parts; the CMX 50 U is a general-purpose machine with 500 x 450 x 400 mm of travel and a 12,000 RPM spindle.
The CMX 50 U has twice the spindle power, 22 kW (30 hp) against 11 kW, and the larger envelope on every axis. The Willemin has three times the spindle speed and is the lighter machine at 4,500 kg (9,921 lb) against 6,600 kg (14,551 lb). Both can run a Fanuc 31i-B5 control.

Advantages
DMG Mori CMX 50 U
- 500 x 450 x 400 mm of travel against 200 x 150 x 250 mm
- 22 kW (30 hp) spindle against 11 kW
- Siemens 840D sl available as well as Fanuc 31i-B5
Willemin-Macodel 701S
- 36,000 rpm spindle against 12,000 RPM
- Lighter machine at 4,500 kg (9,921 lb) against 6,600 kg (14,551 lb)
Verdict
The Willemin-Macodel 701S is for micro-parts such as dental implants, watch movement components, hearing aid housings, miniature connectors and small turbine parts that fit within 200 x 150 x 250 mm and need 36,000 rpm. The CMX 50 U is for general 5-axis work on parts up to 500 x 450 x 400 mm and 200 kg, where 22 kW of spindle power is needed.
