SPECIFICATIONS AND SELECTION METHODS
Widely used for removing excess material and cutting, within various angle grinder and handled cutting wheel machines.
Selection methods by clasification
(1) Mark explaination product standard
Abrasives material explaination
1. Alumunium oxide
Alumunium oxide contains 3% titanium oxide in 1250 Celsius degres oxidation which suitable to grinding high strength tensile materials.
2. Silicone carbide
Harder than alumunium oxyde used for finishing work, low tensile strength materials, such as cast iron, non ferrous metal, non metallic materials.
3. Zirconia (ZrO2)- ceramics material
Combination Alumunium oxyde and zirconia oxyde, as Zirconia alumina grain, applications in cutting, many structurals material and medical tools
(3) Grain Size
increase grite(grain) size mean increase hardness working materials.
coarse soft, cutting ductile materials,fine brittle and hard materials when fine finish jobs requiring.
(4) Speed feeding
(5) Bond
Hold abrasive grain as super adhesive glue.
BF resin bonds. fibre reinfoced woven or non moven, commonly used.
B resin bonds duroplatics
