What is a diamond blade?
A diamond blade is composed of a circular steel core and the diamond
impregnated segments. The segments are seperated by slots in the core.
These
slots assist in cooling the blade during operation by allowing water (wet
cutting) or air (dry cutting) to flow between the segments. The segments or rims
are a mixture of diamond powder and metal powders. The diamonds are industrial
diamonds of different sizes and qualities depending on the material to be cut as
well a the blade type.
How does a diamond blade work?
The individual diamond crystals exposed on the leading edge and the sides of
the segment or rim carry out the cutting. The operator pushes the rotating blade
into the material and the surface diamonds thus exposed mill a groove in the
material. When the blade mills the material, the latter exerts wear on the
blade. During cutting the exposed diamonds may crack
or break. The material simultaneously starts to abrade the metal matrix, which
releases more diamonds.
The more abrasive the material, the more rapid
the tendency to wear down the matrix. Blades for cutting hard, denseless
abrasive materials (such as tile, bricks, stone or cured concrete), require
a softer metal matrix.
This will wear down faster, replacing the worn diamonds
fairly quickly so that the blade continues to cut.
Blades for cutting soft,
abrasive materials (such as green concrete and asphalt), must have a hard,
abrasion-resistant metal matrix in order to retain the diamonds for a longer
time.
Water will prevent the blade from overheating:
It will greatly reduce the amount of harmful dust created by cutting. Remove the
slurry from the cut, and extend the life of the blade.
