Machine Comparison
Mazak UN vs Mazak VC-Ez
Yamazaki Mazak vs Yamazaki Mazak · Vertical Machining Centers
Summary
The Mazak UN and the Mazak VC-Ez are both vertical machining centers, but for different shops. The UN is a compact BT30 production machine for small aluminum parts; the VC-Ez is a CAT No.40 general-purpose series offered in several sizes for job shops.
Every VC-Ez model is larger than the UN: 30 in (762 mm) to 64.17 in (1,630 mm) of X against 20 in (508 mm), 16.14 in (410 mm) to 32.08 in (815 mm) of Y against 13.78 in (350 mm) to 16 in (406 mm), and 20.08 in (510 mm) to 30.12 in (765 mm) of Z against 15 in (381 mm) to 15.75 in (400 mm). The VC-Ez also carries 30 tools against 20 tools. The UN spins faster, at 20,000 rpm against 12,000 rpm.

Advantages
Mazak UN
- 20,000 rpm spindle against 12,000 rpm
- Compact BT30 machine for drilling and tapping lines where machine width decides how many spindles fit
Mazak VC-Ez
- X travel of 30 in (762 mm) to 64.17 in (1,630 mm) against 20 in (508 mm)
- Z travel of 20.08 in (510 mm) to 30.12 in (765 mm) against 15 in (381 mm) to 15.75 in (400 mm)
- 30 tools against 20 tools
- CAT No.40 spindle taper against BT30
Verdict
Choose the Mazak UN for high-volume drilling and tapping of small aluminum parts on a production line, where a 20,000 rpm BT30 spindle and a narrow machine pay off. Choose the Mazak VC-Ez for general 3-axis milling in steel and aluminum, from vise work to plates and mold bases, where a CAT No.40 spindle, 30 tools and X travel up to 64.17 in (1,630 mm) cover a far wider range of parts.
