Overview

The Mazak UN (Universal) is a versatile vertical machining center designed for general-purpose manufacturing across diverse industries. The UN series provides a balanced combination of work envelope, spindle performance, and build quality for shops that handle a wide variety of part types and materials rather than specializing in a single application.

The UN series offers travel of approximately 1,020 x 510 x 460 mm (40.2 x 20.1 x 18.1 in) with a BT 40 spindle at 12,000 RPM and 18.5 kW (25 hp). This work envelope exceeds most 40-taper VMCs in the same class, providing room for medium-to-large parts and multi-part fixturing. The table measures 1,200 x 500 mm (47.2 x 19.7 in) with a maximum load of 1,000 kg (2,205 lb).

The 30-station arm-type ATC with 1.5-second tool-to-tool changes keeps the machine productive on complex parts requiring many tools. Rapid traverse at 42 m/min on X and Y, 36 m/min on Z provides competitive repositioning speed. Roller guide construction on all axes ensures good positioning accuracy and surface finish.

The MAZATROL SmoothG CNC provides conversational programming and G-code capability with 3D simulation. The control supports 4th-axis integration for rotary table work, expanding the machine into light 4-axis machining territory.

Competitors include the Haas VF-3, Okuma GENOS M560-V, and Doosan DNM 5700. New UN machines price between $110,000 and $155,000. The UN fills the gap between entry-level VC-Ez models and production-focused VCN machines in the Mazak vertical machining lineup.

Strengths & Limitations

Strengths

1,020 mm X-travel exceeds most 40-taper VMCs in the class, providing generous room for medium-to-large parts
18.5 kW spindle delivers solid cutting power for both aluminum and steel across diverse material mixes
30-station arm-type ATC with 1.5-second tool changes handles complex multi-operation parts efficiently
42 m/min rapid traverse on X/Y keeps repositioning time short for improved cycle efficiency
MAZATROL SmoothG conversational programming reduces setup time across the varied part families a general-purpose shop handles
1,000 kg table load supports heavy fixtures and multi-part setups

Limitations

General-purpose positioning means it does not excel at any single application the way specialized VMCs do
Roller guide construction may not provide the same heavy-cut rigidity as box-way competitors for aggressive steel roughing
Pricing at $110-155K puts it in a competitive segment with many alternatives from Haas, Okuma, and Doosan
No traveling column variant in the UN series; shops needing that feature should look at the VTC line

Best For

Job shops running diverse part families across aluminum, steel, and cast iron that need a versatile general-purpose VMC Contract manufacturers handling prototype-to-production work across multiple industries Shops stepping up from entry-level VMCs that need more travel, power, and tool capacity Medical and aerospace job shops machining medium-sized structural and housing components Maintenance and repair operations (MRO) needing a capable all-around VMC for diverse one-off and short-run parts Shops wanting Mazak build quality and MAZATROL control in a mid-range general-purpose platform

Frequently Asked Questions

01 What does a new Mazak UN cost?

New UN machines range from $110,000 to $155,000 depending on configuration. Options like through-spindle coolant, probing packages, expanded tool magazines, and 4th-axis prep add to the base price.

02 How does the UN compare to the Haas VF-3?

Both are general-purpose VMCs in a similar size range. The UN offers faster tool changes (1.5 sec vs 4+ sec), faster rapids (42 vs 25 m/min), and MAZATROL conversational programming. The Haas VF-3 counters with lower pricing and simpler maintenance. For production-oriented shops, the Mazak speed advantages add up.

03 What is the difference between the UN and VCN series?

The VCN is the Mazak production-focused VMC line with heavier construction, higher spindle power options, and THERMAL SHIELD thermal compensation. The UN provides similar travel at a lower price point, making it better suited for general-purpose job shops rather than dedicated production environments.

04 Can the UN handle 4th-axis work?

Yes, the UN supports 4th-axis rotary table integration through the MAZATROL SmoothG control. This expands the machine into light 4-axis indexed and simultaneous machining territory for wrapping operations and multi-face part access.
