DIA. CUP WHEEL 115 X 22.23MM DBL ROW COLD PRESSED

TYPE:
Cold pressed, double row.

DIAMETER: ø115mm
BORE/THREAD: Ø22.23mm
MAX RPM: 10,400

Application:

The cup grinding wheel is used with an angle grinder to clean granite,masonry, concrete and stone surfaces.

A diamond blade grinds, rather than cuts through material. The blades typicallyhave segments which contain diamond crystals embedded throughout the segment forgrinding through very hard materials.

What is a diamond blade?

A diamond blade is composed of a circular steel core and the diamondimpregnated segments. The segments are seperated by slots in the core.

Theseslots assist in cooling the blade during operation by allowing water (wetcutting) or air (dry cutting) to flow between the segments. The segments or rimsare a mixture of diamond powder and metal powders. The diamonds are industrialdiamonds of different sizes and qualities depending on the material to be cut aswell a the blade type.

How does a diamond blade work?

The individual diamond crystals exposed on the leading edge and the sides ofthe segment or rim carry out the cutting. The operator pushes the rotating bladeinto the material and the surface diamonds thus exposed mill a groove in thematerial. When the blade mills the material, the latter exerts wear on theblade. During cutting the exposed diamonds may crackor break. The material simultaneously starts to abrade the metal matrix, whichreleases more diamonds.

The more abrasive the material, the more rapidthe tendency to wear down the matrix. Blades for cutting hard, denselessabrasive materials (such as tile, bricks, stone or cured concrete), requirea softer metal matrix.

This will wear down faster, replacing the worn diamondsfairly 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 longertime.
