Floor Scarifiers

A floor milling machine has a rotating drum, typically 180–500 mm wide, fitted with carbide teeth (TCT), which cuts the top layer of concrete or screed. In a single pass it removes a 1–10 mm layer, stripping off paint coatings, adhesives and epoxy resin, and several passes level out substrate irregularities. The resulting dust is extracted by an M- or H-class industrial vacuum cleaner.

A floor milling machine cuts with a drum fitted with carbide teeth and removes a 1–10 mm layer in a single pass — suited to thick coatings and adhesives. A concrete grinder works with diamond segments or pads in a 30–3000 grit range and removes a far thinner layer, leaving a smooth or polished surface. A milling machine prepares a damaged substrate; a grinder finishes an already-cleared floor.

At NORWIT.PL, floor milling machines are supplied primarily by Husqvarna Construction, Dr. Schulze and Enar — from hand-guided machines around 180–250 mm wide to ride-on units with a 300–500 mm drum. Husqvarna Construction offers the widest model range; Dr. Schulze and Enar cover finishing and renovation work. Drums and knives for each brand are in the accessories category.

A floor milling machine is a dedicated tool for removing thick coatings — paint, flooring adhesives and cured epoxy resin. A drum with carbide teeth removes a 1–10 mm layer per pass, so 2–3 passes replace hours of manual chipping on strongly bonded coatings. After milling, the surface has enough roughness for a new screed or resin floor.

For large industrial surfaces — halls, warehouses or car parks above a few hundred square metres — ride-on machines with a wide 300–500 mm-plus drum work well, driven from an operator's seat. This design holds a constant milling depth of around 1–10 mm over many hours of work. Smaller rooms are covered by a compact machine 180–250 mm wide.

Floor milling machines come in an electric version — single-phase 230 V rated up to 2–3 kW, three-phase 400 V rated 4–7.5 kW — and a petrol version with an engine typically rated 4–9 HP. Electric suits indoor work; petrol works outdoors or where there's no power connection. Three-phase 400 V models handle wider drums and longer continuous runs than single-phase ones.

Working width is matched to the scale of the surface. Compact hand-guided machines with a drum 180–250 mm wide suit rooms up to a few dozen square metres. Ride-on machines with a 300–500 mm drum or wider work in halls above a few hundred square metres, where speed matters most. A narrower drum gives higher unit pressure; a wider one covers a large surface faster.

Milling a floor generates a large amount of fine concrete dust, so a professional floor miller has a dust-extraction port connected to an M- or H-class industrial vacuum cleaner — without it, indoor work breaches health-and-safety rules. A vacuum with a 15–75 l tank capacity extracts dust continuously, extending filter life and cutting clean-up time. Industrial vacuum cleaners for this use are in a separate NORWIT.PL category.
