Bernardo Milling and Drilling Machine KF 28 Top with 3-Axis Display

Bernardo Mill-Drill KF 28 Top with automatic feed and 3-axis digital readout ES-12 V

The Bernardo KF 28 Top mill-drill is a versatile and compact machine, suitable for workshops and mechanical laboratories. Thanks to its 2-stage gearbox and continuous speed adjustment (50–2600 rpm), it guarantees optimal adaptation to different materials.

Equipped with a ±90° tilting head, a 700 x 180 mm cross table with 430 x 120 mm travels and automatic feed on the X-axis, it allows for milling, boring, angular drilling, and tapping operations. The digital indicators for speed and spindle travel, along with the standard 3-axis digital readout ES-12 V, ensure optimal control of the machining process.

The dovetail guides on the X, Y, and Z axes, adjustable with gibs, and the precision tapered roller bearings guarantee concentricity ≤0.015 mm. A robust cast iron structure, EMC filter, adjustable guard, and LED lamp complete a package that combines precision and safety.

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-sized jobs. 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, greater travels — for medium-sized parts in continuous production. The FM series has a 360° tilting 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 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 "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. Please check the specific model description.

Are spare parts available?

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

How much workshop space is needed 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 free space on each side for safe operation. Contact Krollit for full dimensions of the specific model.
