Who uses the UWF 90 V and for what
The Bernardo UWF 90 V is the mid-range universal milling machine in the UWF family, sized for mechanical workshops with medium to large part production. It represents a dimensional leap compared to the UWF 80 E: 1,270×280 mm table (vs 1,000×240), 750 mm X-travel (vs 590 mm), 2.2+2.2 kW motors (vs 0.85/1.5 + 1.5 kW). The dedicated Z-axis positioning motor with 660 mm/min rapid feed is a distinguishing feature: it allows for quick head repositioning between operations without manually operating the handwheel. The 12 speed stages on the horizontal spindle (vs 9 on the UWF 80 E) cover a wider range for various applications. The automatic spindle feed with 3 values (0.08, 0.15, 0.25 mm/rev) allows for repeatable precision machining. The heavy 1,310 kg cast iron structure with dovetail guides ensures stability for intensive cycles. In Krollit customer workshops, it is chosen by professional mechanical workshops with regular production, prototyping and small-batch production labs, and general mechanical processing workshops.
Its place in the Bernardo range
The UWF 90 V is the central model in the Bernardo UWF family. Below it: UWF 80 E (1,000×240 mm table, 980 kg weight) and UWF 80 E Vario (with vertical speed inverter). Alongside: UWF 90 V with pneumatic clamping DIN 2080 (subsequent version with quick tool change); UWF 90-1270 (identical 1,270×280 mm table, but 0.85/1.5 kW vertical motor instead of 2.2 kW: less powerful version). Above: UWF 95 N (1,600×360 mm table, 2,200 kg weight, with pneumatic clamping) for large industrial parts; UWF 110 (360° universal head) and UWF 150 (top of the range with ISO 50, 4 kW motor). The choice between UWF 90 V and UWF 90-1270 depends on the power required on the vertical spindle: the 90 V with 2.2 kW handles more demanding operations; the 90-1270 with 0.85/1.5 kW is sized for lighter operations at a lower cost. For workshops with regular production on standard steels and alloys, the UWF 90 V is correctly sized.

| Mechanical workshop with regular production | Recommended | Double spindle with 2.2+2.2 kW motors, 1,270×280 mm table, Z-axis positioning motor. Sized for daily professional use on medium-to-large parts. |
| Prototyping and small-batch production lab | Recommended | 12 horizontal and 8 vertical stages cover different speeds for variable materials. Automatic spindle feed with 3 values for repeatable precision machining. |
Not suitable for: workshops requiring frequent quick tool changes (the UWF 90 V with DIN 2080 pneumatic clamping is correctly sized); production of large parts beyond the 1,270×280 mm table (UWF 95 N or UWF 150); exclusive use at low powers (the UWF 90-1270 with 0.85/1.5 kW vertical motor is more economical); high-volume series production (CNC).

Frequently Asked Questions
What is the difference with the UWF 90-1270?
The two milling machines share the table (1,270×280 mm), travels (750/230/300 mm), and spindle type (ISO 40 vertical + horizontal). The only difference is in the power of the vertical spindle: the UWF 90 V has 2.2 kW, the UWF 90-1270 has 0.85/1.5 kW.
The UWF 90 V with a more powerful motor is sized for standard professional machining on medium steels and alloys. The UWF 90-1270 with a lower motor is sized for lighter machining or for workshops with limited needs, at a lower cost. For growing workshops or those with varied operations, the UWF 90 V is strategically preferable.
Is the Z-axis positioning motor really necessary?
Yes, for operations with frequent repositioning. Without a Z motor, the operator must manually operate the vertical axis handwheel for each repositioning (a slow and tiring operation for large movements).
The 660 mm/min rapid feed on the Z-axis allows 100 mm movements in 9 seconds. In comparison, the manual handwheel takes 30-60 seconds for an experienced operator. For series production or operations with frequent height changes, the time saving is significant. For static machining on a single piece, the difference is less noticeable.
What is the purpose of the automatic spindle feed with 3 values?
It allows setting the working feed of the spindle for drilling/boring: 0.08 mm/rev for hard steels and finishing, 0.15 mm/rev for standard operations, 0.25 mm/rev for soft steels and roughing.
The automatic feed maintains constant speed without operator intervention: the spindle advances by itself during machining while the operator can control other aspects. For precision drilling or boring, it is an essential feature. Without automatic feed, manual pushing produces speed variations that worsen the hole finish.
The 750 mm X-travel is 'manual' - what does that mean?
It means that the full 750 mm longitudinal travel can only be achieved with manual feed (handwheel). The automatic feed covers a smaller portion of the travel.
On many universal milling machines, automatic feed is limited to a portion of the travel for mechanical and cost reasons. For standard operations, automatic feed is more than sufficient. For positioning movements at the limits of the travel, the operator uses the handwheel. Check the dimensions of typical parts before purchasing: for parts requiring automatic machining beyond the automatic feed zone, consider higher-end models.
Are 12 speed stages on the horizontal spindle too many?
No. The wider speed range (40-1,300 rpm) requires more stages to cover it correctly. Horizontal milling typically operates at lower speeds than vertical milling (tools are often larger, e.g., face milling cutters), so the 40-1,300 range is adequate.
On a horizontal spindle, face milling cutters can have Ø 100-300 mm, requiring specific peripheral speeds for each material. The 12 stages allow finding the most appropriate speed for each tool-material combination. On the UWF 90 V, speed change is mechanical via levers.
