VFG-480 Floor Grinder: Professional 480 mm Concrete Surface Preparation

The VFG-480 is a heavy-duty, walk-behind floor grinder developed for professional concrete surface preparation. Its 480 mm working diameter, 2.2 kW single-phase motor and 380 rpm grinding-head output provide a practical balance of floor coverage, cutting force and operator control.

Designed for medium-to-large open areas, the VFG-480 supports concrete grinding, surface levelling, coating removal and staged polishing. A perimeter dust shroud, external vacuum connection, adjustable handle and removable weight system help the machine adapt to different jobsite conditions.

A Professional Working Platform

Main components of the VFG-480

The VFG-480 brings the main requirements of professional floor preparation into one straightforward platform:

  • 480 mm nominal grinding diameter for productive coverage
  • 2 kW single-phase motor in the listed 220 V / 50 Hz configuration
  • 2,850 rpm motor speed reduced to a 380 rpm working output
  • Three-disc working system for stable floor contact
  • Perimeter dust shroud and dedicated external-vacuum port
  • Two removable 11 kg weights for balance and head-load adjustment
  • Adjustable, foldable handle with operator controls close to the grips
  • Rear wheels for movement around a level jobsite

These features make the machine suitable for contractors who need more working capacity than a compact grinder without moving to a large ride-on or remote-control system.

480 mm Coverage for Open Floor Areas

Each pass covers a nominal 480 mm path. This working width is well matched to warehouses, workshops, parking structures, commercial interiors, production areas and renovation projects where substantial floor area must be processed efficiently.

The listed production rate is 50–75 m²/h. Actual output depends on the floor condition, concrete hardness, coating thickness, diamond tooling, grit, travel speed, overlap and the number of required passes. The wide head is most productive in open areas; edges and tight corners are normally completed with a separate edge grinder.

Low-Speed Output with Useful Grinding Torque

VFG-480 motor and reduction-drive detail

The electric motor runs at a listed 2,850 rpm, while the working output is 380 rpm. The reduction system converts motor speed into the lower-speed torque required to keep diamond tooling cutting under load.

This operating character allows the VFG-480 to do more than buff a finished surface. With suitable tooling, it can open dense concrete, remove surface contamination, reduce uneven areas and prepare the floor for progressively finer grinding or polishing steps.

Three-Disc Grinding System

The underside uses three working discs within the 480 mm grinding area. The multi-disc arrangement distributes tool contact across the head and gives operators a practical platform for different grinding and polishing processes.

Tooling can be selected for the required result:

  • Coarse diamond tools for aggressive cutting and coating removal
  • Medium grits for scratch refinement and floor levelling
  • Fine grinding tools and polishing pads for later finishing stages
  • Bond specifications matched to hard, medium or soft concrete

Available tool-holder systems and compatible tooling should be confirmed with the final machine configuration. Correct tooling has a direct influence on cutting speed, scratch pattern, wear rate and overall project cost.

Dust Extraction and Adjustable Head Loading

VFG-480 vacuum port and removable weight system

The VFG-480 is designed for connection to an external industrial dust extractor. Its perimeter shroud contains dust around the working head, while the vacuum port provides a direct connection close to the grinding zone. The machine does not contain a built-in vacuum.

Effective extraction improves jobsite visibility, helps keep abrasive debris away from the working area and supports the control of respirable crystalline silica. Extractor capacity, hose diameter, filtration and personal protective equipment must be selected for the applicable work and local regulations.

Two removable 11 kg weights allow the operator to adjust machine balance and effective head loading. Additional head pressure can support stronger cutting action, while repositioning or removing weight can make the machine easier to start and control in demanding conditions.

Controls Positioned for the Operator

The control area is located close to the dual-grip handle. The photographed configuration includes a start/stop switch, electrical display and prominent emergency-stop button, keeping essential functions within easy reach.

The handle position can be adjusted for the operator and the task. A dedicated tooling position provides underside access when the machine is stopped, isolated from power and safely tilted back. This arrangement reduces unnecessary handling during tool changes and routine inspection.

Compact Storage and Planned Transport

The folding handle reduces the machine’s storage footprint, and the rear wheels support movement across a level floor. At a listed net weight of 170 kg, the VFG-480 remains a professional heavy machine. Ramps, lifting equipment or a suitable vehicle loading system should be included in the transport plan.

The compact folded profile is useful for equipment rooms, rental fleets and service vehicles where storage space matters, while the substantial machine mass contributes to stable contact during grinding.

Typical Applications

The VFG-480 is a strong match for:

  • Preparing concrete before epoxy, polyurethane or other coating systems
  • Removing paint, adhesive residue and surface contamination
  • Levelling local high points and improving floor flatness
  • Opening dense concrete before densification or polishing
  • Progressive grinding and polishing with the appropriate tooling
  • Maintaining and renovating warehouses, workshops, garages and commercial floors

The machine is intended for trained professional operators. A complete working setup includes compatible diamond tooling, an industrial dust extractor, correctly rated electrical supply and appropriate personal protective equipment.

A Practical Core Machine for Floor-Preparation Teams

The VFG-480 combines productive 480 mm coverage with a stable three-disc grinding head, low-speed working torque, adjustable loading, source-level dust extraction and a foldable operator frame. The result is a versatile machine for contractors, rental fleets and construction teams that need reliable performance across several stages of concrete floor preparation.

For the best configuration, match the machine to the actual floor, coating, power supply, required finish and daily working area. Vleader can then recommend the appropriate electrical version, tool-holder system, diamond tooling and dust-extraction setup.
