Who uses the BF 45 HSV Vario and for what
Precision mechanical workshops, mold makers, and industrial laboratories use this large-format drill-milling machine for complete machining operations: drilling steel up to Ø32 mm and cast iron up to Ø40 mm, face milling up to Ø80 mm with automatic spindle feed. The Delta Vario speed inverter (75–2,750 rpm) and the 362 kg heavy cast iron structure support intense work cycles on a 730 x 210 mm table.
Its place in the Bernardo range
The Bernardo BF 45 HSV Vario is positioned in the high segment of the Bernardo drill-milling machine range, with a 362 kg cast iron structure for continuous industrial use. Above this range, Bernardo only offers UWF universal milling machines with automatic feed on all axes. Below the BF 45 HSV Vario, the range offers the BF 28 BDC and BF 30 G series with more compact structures (130-190 kg) and lower drilling capacities.
Krollit logistics and support
Bernardo shipping in 5-9 business days (7 days to the South). For original Bernardo spare parts, shipping 3-5 business days from Krollit warehouse. Italian customer support available for technical documentation, product sheets, and spare parts order management. Krollit has been an official Bernardo distributor since 2007.
Who is the BF 45 HSV Vario for
| Profile | Compatibility | Reason |
|---|---|---|
| Precision mechanical workshops and mold making | Suitable | Drilling Ø32 mm steel / Ø40 mm cast iron, milling Ø80 mm, 362 kg structure |
| Industrial laboratories for multi-shift operations | Suitable | 730 x 210 mm table, 2.2 kW 400 V motor, 3-step automatic spindle feed |

Frequently asked questions
What are the drilling and milling capacities of the BF 45 HSV Vario?
Drilling steel up to Ø32 mm and cast iron up to Ø40 mm, face milling up to Ø80 mm.
The stated capacities refer to standard unhardened steels (e.g., C40, S235). For harder materials or alloy steels, the actual capacity may be lower: in this case, it is advisable to reduce the rotation speed and feed rate to avoid stressing the spindle and tools.
How is the spindle speed adjusted on the BF 45 HSV Vario?
The machine has a continuously adjustable Vario speed in the range of 75–2,750 rpm.
The Vario adjustment allows the speed to be finely adapted to the material and tool diameter, without having to change belts or gears. For face milling of soft steels, the lower range is typically used, while for small diameter holes in aluminum, the higher range is used.
What power supply and motor does the BF 45 HSV Vario have?
1.5 kW (S1 continuous) / 2.2 kW (S6 intermittent) motor with 400 V power supply.
The motor requires a 400 V three-phase power supply. Check for a three-phase line in the workshop before purchasing. For environments without three-phase power, the Bernardo range offers equivalent 230 V single-phase models, but with lower machining capacities.
What are the table dimensions, travel, and spindle taper of the BF 45 HSV Vario?
Cross table 730 x 210 mm with X/Y travel of 495 / 200 mm, MT 4 spindle taper, 120 mm spindle stroke.
The MT 4 spindle taper is an international standard: accessories (self-centering chucks, end mill holders, reduction arbors) are commonly available. The table travels allow for machining pieces that fall within the effective usable dimensions (X/Y travels net of clamping obstructions).
How much does the BF 45 HSV Vario weigh and what type of installation does it require?
The machine weighs approximately 362 kg and requires installation on a flat industrial floor, with a dedicated base and 400 V electrical connection.
For a 362 kg machine, an workshop floor with adequate foundation (standard reinforced concrete) and base fastening with expansion anchors is recommended to minimize vibrations during more demanding machining operations. The electrical connection must be performed by qualified personnel.
