HOW TO SELECT THE RIGHT GRINDING WHEEL
2
The grinding wheel is an abrasive cutter. In a
grinding wheel, the abrasive grains are
distributed on the wheel's edges to perform the
cutting function. Thousands of those hard, chewy
grains move against the workpiece to chop away
tiny chips of fabric. These abrasive grains stick
together by a bond, a mixture of selected clays,
and separated by pores.

TYPES OF ABRASIVE GRAINS AVAILABLE FOR GRINDING
DISCS.
Each class has unique properties when it involves
hardness, strength, fracture toughness, and
resistance to impact. The selection of the
abrasive is inevitably associated with the fabric
of the workpiece.

• Aluminum Oxide

Aluminum Oxide is the most common abrasive
utilized in grinding wheels. It's generally
recommended for grinding materials like chrome
steel and gear steels, but it is the right choice
for cutting high tensile aluminum and bronze
alloys.

• Silicon Carbide

Harder than standard alumina with a sharp
abrasive grain, it's mostly used for grinding
gray iron, chilled iron, brass, soft bronze,
aluminum, and stone, rubber, and other
non-ferrous materials.
5

• Zirconia Alumina

Zirconia Alumina is mainly used for rough
grinding applications where high stock removal is
required. This grain is related to high-tech
resin bonds.
6

• Ceramic Alumina

This ceramic grain features a unique
microcrystalline structure that's
self-sharpening. This abrasive is exceptionally
hard and powerful. It's primarily used for
precision grinding in demanding applications on
steels and alloys that are the foremost difficult
to grind.

GRINDING WHEEL BOND TYPE

• Strong bonds

Such bonds are recommended for soft materials,
small or narrow areas of contact, or longer wheel
life.

• Weak bonds, or soft grades

Such bonds are preferable for hardened materials,
like hardened tool steels or carbides, giant
areas of contact, or rapid stock removal.
