Who uses the KNF 2 P and for what
The Bernardo KNF 2 P is a specialized milling machine for producing double grooves on wooden profiles for installing double glazing, seals, and inserts in window and door frames. The two 6 mm cutters, spaced 28 mm apart, work simultaneously to create two parallel grooves in a single pass — an operation that would require two separate passes with a single cutter, risking positioning errors. The pneumatic workpiece clamping frees both hands of the operator and ensures repeatability for series of identical profiles. With 32,000 rpm, it produces clean finishes on solid and laminated wood. In Krollit customers' workshops, it is used by joiners and specialized workshops manufacturing wooden frames.
Who is the Bernardo KNF 2 P for?
| Profile | Compatibility | Reason |
|---|---|---|
| Hobbyist | Not suitable | Specialized machine for serial production of window and door frames. |
| Joiner / specialized carpenter | Ideal | Double grooving in one pass with pneumatic clamping: the solution for serial production of profiles for double glazing. |
| General carpentry | Adequate | Useful if window and door frames are produced frequently. For occasional grooving, a standard spindle moulder is sufficient. |

Frequently Asked Questions
Is the 28 mm distance between the cutters fixed or adjustable?
The standard distance between the cutters is 28 mm — optimized for the standard seat of double glazing in wooden frames. Contact Krollit to check if configurations with different distances are available for specific needs.
Does the KNF 2 P require a dedicated compressor?
Yes. The pneumatic workpiece clamping and feed control require a compressor with 6–8 bar pressure and sufficient flow for continuous use. A compressor with a 50–100 liter tank and a minimum flow of 200 l/min is adequate for intermittent professional use.
Does it also work on PVC or aluminum profiles?
The KNF 2 P is designed for solid and laminated wood. For PVC or aluminum profiles, 6 mm HSS cutters may not be optimal — specific tools for non-ferrous materials are needed. Contact Krollit to assess compatibility with materials other than wood.
Are spare parts (cutters, cutter holders) available?
Yes. Original Bernardo spare parts for the KNF 2 P are available with 3–5 working days shipping.
How much space is needed in the workshop?
Footprint 400 × 620 × 480 mm — very compact. Requires connection to compressed air 6–8 bar and a 230V socket. For handling profiles, free space is needed in front of and behind the 390 mm guide.
