Machine Comparison
Mazak SVC vs Mazak UN
Yamazaki Mazak vs Yamazaki Mazak · Vertical Machining Centers
Summary
The Mazak SVC and the Mazak UN are vertical machining centers of very different sizes, built for different jobs. The SVC is a long-bed machine with 120 in (3,048 mm) to 200 in (5,080 mm) of X travel and a CAT No.40 spindle. The UN is a compact BT30 production machine with 20 in (508 mm) of X travel, made to fit many spindles into a line.
The SVC has more travel on every axis, 20.08 in (510 mm) of Y and Z against at most 16 in (406 mm) and 15.75 in (400 mm), and its table carries 5,291 lb (2,400 kg) to 7,496 lb (3,400 kg) against 331 lb (150 kg). The UN spins faster at 20,000 rpm against 15,000 rpm. Both rapid at 4,724 ipm (120 m/min).

Advantages
Mazak SVC
- X travel of 120 in (3,048 mm) to 200 in (5,080 mm) against 20 in (508 mm)
- Table load of 5,291 lb (2,400 kg) to 7,496 lb (3,400 kg) against 331 lb (150 kg)
- 20.08 in (510 mm) of Y and Z travel against 13.78 in (350 mm) to 16 in (406 mm) of Y and 15 in (381 mm) to 15.75 in (400 mm) of Z
- CAT No.40 spindle taper against BT30
Mazak UN
- 20,000 rpm spindle against 15,000 rpm
- Compact machine for production lines, at 9,700 lb (4,400 kg) to 13,228 lb (6,000 kg) against 28,660 lb (13,000 kg) to 57,320 lb (26,000 kg)
Verdict
These machines serve different jobs. Choose the Mazak SVC for long aluminum extrusions, rails and rows of fixtures, where X travel up to 200 in (5,080 mm) and a table rated to 7,496 lb (3,400 kg) are the point. Choose the Mazak UN for high-volume drilling and tapping of small aluminum parts and castings, where a 20,000 rpm BT30 spindle and a narrow machine let a line run many spindles.
