A concrete cutting saw works by using a powerful engine to rotate a specialized blade, typically a diamond blade, that grinds through concrete.
Here's a breakdown of the process:
-
Power Source: Concrete saws are powered by various sources, including:
- Gasoline engines: Provide high power and portability.
- Hydraulic pressure: Offers smooth, consistent power, often used in heavy-duty applications.
- Pneumatic (compressed air): Commonly used in enclosed spaces due to lower emissions.
- Electric motors: Suitable for indoor use and provide quieter operation.
-
Engine Operation: The chosen engine drives the saw's rotating mechanism.
-
Blade Rotation: The engine's power is transferred to the blade, causing it to spin at high speeds.
-
Diamond Blade: The cutting action is primarily performed by a diamond blade. These blades aren't solid diamond, but instead, have diamond segments bonded to a steel core. The diamonds are extremely hard and abrasive, allowing them to grind through the concrete.
-
Cutting Process: As the blade rotates and comes into contact with the concrete, the diamond segments grind away the material. The blade essentially wears away the concrete through abrasion.
-
Cooling and Dust Suppression: Water is often used to cool the blade and suppress dust during cutting. This increases the blade's lifespan and improves visibility.
In short, a concrete saw uses a powerful motor to spin a diamond-tipped blade that grinds away at the concrete until it is cut.
