Bernardo Drill and Mill BF 45 HSV Vario

Bernardo Drill-Milling Machine BF 45 HSV Vario – Power, Precision, and Variable Speed

The Bernardo BF 45 HSV Vario drill-milling machine is a professional machine designed for high performance and versatility. Equipped with a Delta frequency inverter, it offers continuous speed regulation (75–2750 rpm) while maintaining optimal torque even at low speeds.

With a drilling capacity of up to Ø 32 mm in steel and milling capacity of up to 80 mm, it is suitable for workshops and laboratories. The tiltable head from -90° to +90°, the 730 x 210 mm cross table, and the 495 x 200 mm travels allow for a wide range of applications: keyway milling, surfacing, angled drilling, and chamfering.

Hardened gears in an oil bath, a heavy steel column, and dovetail guides ensure stability and long life. Standard features include: automatic spindle feed, threading device, adjustable guard, digital indicators, cooling pump, and LED light.

Frequently Asked Questions

What is the difference between the KF series and the BF/FM series in the Bernardo range?

The KF series (KF 16, KF 20, KF 25, KF 28) is the compact range: smaller tables, MT2/MT3 tapers, suitable for workshops with limited space and small-to-medium size machining. The BF series (BF 25, BF 30, BF 35, BF 40, BF 45) and FM series (FM 40, FM 45, FM 50, FM 55) are the professional versions: larger tables, MT3/MT4 tapers, more powerful motors, longer travels — for medium-sized parts in continuous production. The FM series has a 360° tiltable head, which the KF does not.

What do the suffixes "Vario" and "HSV" mean?

Vario: continuously adjustable spindle speed without changing belts. HSV: spindle head with tilt from −90° to +90° (Head Swivel Variable). BDC: integrated 3-axis digital readout (Digital Readout). The combination HSV + Vario is the most flexible configuration for workshops working with different materials and geometries.

Is the 3-axis DRO included as standard or is it an option?

It depends on the model. Models with "BDC", "DT 40", "ES-12V" or "with 3-axis display" in the name include the digital readout as standard. Models without this designation do not include it — it is available as an optional accessory. Check the specific model description.

Are spare parts available?

Original spare parts available with 3–5 business days shipping. Customer support in Italian available.

How much space is needed in the workshop for the BF/FM series?

BF and FM milling machines are stationary workshop machines — not portable. Consider space for X and Y axis travels plus at least 60 cm clear space on each side for safe operation. Contact Krollit for full dimensions of the specific model.
