Mazak MEGA Series vs Mazak MU Series
Yamazaki Mazak vs Yamazaki Mazak · Horizontal Machining Centers
Summary
The Mazak MEGA Series and the Mazak MU Series are both Mazak horizontal machining centers on the MAZATROL SmoothG CNC, but they sit in different size classes and serve different jobs. The MEGA is a heavy CAT 50 machine with 1,300 x 1,100 x 1,200 mm of X/Y/Z travel; the MU is a compact CAT 40 (BIG-PLUS) machine with 560 x 560 x 630 mm.
The MEGA is built for torque: 1,249 Nm (921 ft-lb) and 85 kW (114 hp) on its short-duty rating, against 119 Nm (88 ft-lb) and 22 kW (30 hp), with 60 tools standard and up to 348 optional against 40 (60 or 80 optional). The MU is built for speed: 15,000 RPM (20,000 RPM optional) against 4,000 RPM, and 60 m/min (2,362 ipm) rapids against 36 m/min (1,417 ipm).

Verdict
These machines serve different jobs. Choose the Mazak MEGA Series for heavy roughing of titanium, Inconel, steel and cast iron, such as large valve bodies, manifolds and castings, where 1,249 Nm at a CAT 50 spindle sets the removal rate. Choose the Mazak MU Series for small aluminum and cast iron brackets, housings, covers and precision parts, where 15,000 RPM and 60 m/min rapids drive high-volume cycles in a compact cell.
