Wheel Selection

OPERATIONS

Aluminum oxide and silicon carbide wheels are marked in a somewhat uniform manner by all the major manufacturers. Understanding these markings will help you understand the capabilities of various wheels. Always refer to the manufacturer’s grinding recommendations when selecting a wheel for your project.

The basic format for wheel numbering is:

Prefix

Abrasive

Grit

Grade

Bond

Type

Size

Type

 

 

36

A

60

L

V

The most common abrasive types used are A for Aluminum Oxide and C for Silicon Carbide, and occasionally SG for seeded gel. The prefix is the manufacturer’s designation for a particular type.

The grit size is a number referring to the size of the abrasive grain in the wheel. The lower the number the coarser the wheel—10 is a very coarse wheel for roughing and 220 is usually the upper range for fine finish work.

Grade is an indication of the hardness of the wheel, with A being softest to Z the hardest.

Bond Type refers to the type of bonding material used to hold the abrasive material. Most general purpose wheels will have a V indicating Vitrified clay is used, providing a high strength and good porosity. The other most common is B for resin where synthetic resins are used. These are used to grind cemented carbide and ceramic materials.

There may be other numbers inserted that have meaning for a particular type of wheel. Refer to the manufacturer’s technical data for a complete explanation.

DO NOT use this grinder with a liquid cooling system required for wet grind- ing wheel operations. Ignoring this warning can lead to electrocution.
