Grinding is an abrasive process that utilises a machine outfitted with grinding wheel and/or cutting accessories. This machining process falls under cutting as it has the ability to cut through non-metallic surfaces such as Stone Marble and Concrete.
Concrete grinders are commonplace in the construction, manufacturing, industries as they are used to create finishes for a variety of applications from preparing a surface for adhesion or for buffing and polishing the surface for a decorative polished concrete.
How does a concrete grinder work?
Floor grinding and polishing models grind concrete floors to remove surface materials in a fast and efficient manner. Whether you are working on concrete Stone or marble, a grinder can also remove adhesives, membranes, or mortar from off its surface.
Although concrete grinders are used for concrete floor grinding and polishing are considered power tools, they often only remove a thin layer of material from the surface of workpieces per pass. Typically, diamond grinding tools only remove between 0.25 mm to 0.50 mm of material. Industrial or heavy-duty grinders with correct diamond tooling or other tooling can grind depths of up to 6 mm of material from the workpiece.
Some of the most common workpieces that undergo grinding and polishing are:
- Concrete Floor
- Concrete Benchtops
- Natural Stone
- Marble
- BlueStone
- Pavers
The type of finish and workpiece material will determine the type of concrete grinder to purchase. For instance, if you plan on working on a small space, hand-held concrete grinder is more than adequate. If you intend to use a grinder to clean surfaces and remove graffiti or other coating or glues from concrete, a handheld model that delivers up to 11,000 RPM using a 10 AMP motor is highly recommended. If you intend to grind large open areas such as tennis courts, domestic housing areas such as patios kitchens and others, or commercial large areas such as parking lots shopping malls and Industrial workshops, a Large 3 Phase grinder would be best for productivity and economic reasons.
Make sure to check other accessories and attachments that are included in the set you plan on buying. A small concrete grinder that can be used for small to medium spaces is ideal not only for homeowners but for those who use them in their trade, too as there is always small areas that the large grinders cannot reach.
