Bernardo Milling/Drilling Machine FM 55 HSV Vario with 3-Axis DRO

Bernardo drilling-milling machine FM 55 HSV Vario with 3-axis digital display ES-12 V and automatic X-axis feed

The Bernardo FM 55 HSV Vario drilling-milling machine is a professional machine designed to meet the needs of mechanical workshops and laboratories. Thanks to the Delta frequency inverter, the spindle speed can be continuously adjusted (75–2750 rpm) with optimal torque even at low speeds.

Equipped with automatic table feed with rapid traverse on the X-axis and automatic spindle feed with 3 selectable feeds, the machine ensures productivity and precision. The ±60° tilting head allows for angular machining, while the 800 x 240 mm cross table with 420 x 200 mm travels offers ample space for milling and drilling.

Standard features include: 3-axis digital display ES-12 V, tapping device, cooling pump integrated into the cast iron base, adjustable guard, and LED light. A robust and complete machine, suitable for intensive milling and drilling operations.

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 operations. 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° tilting head which the KF series 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 position display (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 the designation "BDC", "DT 40", "ES-12V" or "with 3-axis display" in the name include the digital display as standard. Models without this designation do not include it — it is available as an optional accessory. Please check the specific model description.

Spare parts available?

Original spare parts available with 3–5 working 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 fixed workshop machines — not portable. Consider the space for the X and Y axis travels plus at least 60 cm clear space on each side for safe operation. Contact Krollit for the complete dimensions of the specific model.
