Who uses the UWF 150 and for what
The Bernardo UWF 150 is the top of the range of Bernardo universal milling machines, sized for industrial workshops with professional high-precision production on large workpieces. A leap in class compared to the UWF 90/95: ISO 50 spindle taper (vs ISO 50 - larger and more powerful tool holders), 4 kW motors (vs 2.2 kW), 1,650×360 mm table (the largest in the family). The ISO 50 taper is an industrial feature: it allows for larger tools (milling cutters up to Ø 100-150 mm) with higher torque transmission. The 4 kW motors (more than double the 2.2 kW of the lower UWF models) handle heavy-duty machining on hard steels and large tools without compromise. The rectangular guides on Y and Z combine rigidity on two of the three axes most stressed during milling. The swiveling control panel is an ergonomic feature: the operator rotates the controls to the most comfortable position based on the machining operation. The automatic feeds on all 3 axes (8 stages) and rapid feeds of 1,290/1,208/513 mm/min (X/Y/Z) optimize cycle times for series production. In Krollit customer workshops, it is chosen by industrial mechanical workshops with precision production on large workpieces, metal fabrication shops with complete machining operations, and laboratories that require the highest professional level from Bernardo in universal milling machines.
Its place in the Bernardo range
The UWF 150 is the pinnacle of the Bernardo UWF range, the only one with an ISO 50 taper. Below it: UWF 95 N (1,600×360 mm table, ISO 40, 2.2 kW motors, 2,200 kg weight) for standard professional production; UWF 110 (360° universal head, 1,120×260 mm table, ISO 40); UWF 90 V and UWF 90-1270 (1,270×280 table, ISO 40); UWF 80 E and UWF 80 E Vario (1,000×240 table, ISO 40). Key difference UWF 150 vs UWF 95 N: ISO 50 taper (vs ISO 40) and 4 kW motors (vs 2.2 kW). For heavy industrial machining on hard steels or large tools (over Ø 50 mm), the UWF 150 is correctly sized. For standard production on mild steels and medium alloys with tools up to Ø 50 mm, the UWF 95 N is correctly sized at a significantly lower cost. The investment in UWF 150 is justified for workshops with high power requirements, ISO 50 tools, and continuous intensive cycles. For workshops that already have ISO 40 tool sets, switching to ISO 50 requires tool updates: plan accordingly.

Frequently Asked Questions
What is the key difference between ISO 50 and ISO 40?
The ISO 50 has a larger taper (nominal Ø 69 mm vs 44 mm for ISO 40), drawbar M24 (vs M16). It transmits significantly higher torque: ISO 50 tools are dimensioned for heavy industrial machining.
For standard operations with tools up to Ø 50 mm, ISO 40 is sufficient. For large tools (Ø 80-150 mm) or heavy-duty machining on hard steels, ISO 50 is correctly sized. The ISO 50 taper is a characteristic of professional industrial milling machines; among Bernardo UWF models, only the 150 offers it.
Do the 4+4 kW motors require special electrical sizing?
Yes. Only one spindle operates at a time (4 kW), but at startup, it requires peak power that necessitates a properly sized industrial meter. For workshops without an adequate industrial power line, check with your electricity provider.
A 4 kW motor at startup can reach peaks of 6-8 kW: industrial meters of 10-15 kW are recommended. For workshops with other machines running simultaneously, the total sizing is important. The UWF 150 is sized for industrial workshops with an adequate electrical line.
How do the rectangular guides on Y and Z (and not X) perform?
The rectangular guides on Y and Z provide maximum rigidity on the two axes most stressed during milling (feed and depth). The X-axis (longitudinal movement of the workpiece) is less stressed and maintains adequate standard guides.
The design choice optimizes the rigidity/cost ratio: rectangular guides on all 3 axes would be more expensive without proportional benefits. On the two most critical axes (transverse Y, vertical Z), the rectangular guides maintain precision under load even with large tools and heavy workpieces.
Is the swiveling control panel really useful?
Yes. It allows the operator to position the controls in the most ergonomic area based on the working position: in front of the machine for standard operations, laterally for machining large or angular workpieces.
On traditional milling machines with fixed controls, the operator must adapt to the position of the controls. For prolonged operations, this lack of ergonomics leads to fatigue. The swiveling panel is a characteristic of high-end industrial milling machines; in Bernardo UWF models, it is exclusive to the 150.
What type of machining justifies the investment in UWF 150?
Industrial machining of large and heavy workpieces (machine bases, industrial molds, machine components); milling on hard steels with large tools; series production with intensive cycles; precision tolerances on voluminous workpieces.
For general artisan workshops, the UWF 95 N (ISO 40, 2.2 kW) or the UWF 90 models are correctly sized at a significantly lower cost. For industrial workshops with regular precision production on heavy workpieces, the UWF 150 repays the difference with greater productivity and tighter tolerances.
