Specification Of Grinding Wheel

Specification of grinding wheel
A grinding wheel requires two types of specification
(a) Geometrical specification
(b) Compositional specification

(a) Geometrical specification
This is decided by the type of grinding machine and the grinding operation to be
performed in the workpiece. This specification mainly includes wheel diameter, width
and depth of rim and the bore diameter. The wheel diameter, for example can be as
high as 400mm in high efficiency grinding or as small as less than 1mm in internal
grinding. Similarly, width of the wheel may be less than an mm in dicing and slicing
applications.

(b) Compositional specifications
Specification of a grinding wheel ordinarily means compositional specification.
Conventional abrasive grinding wheels are specified encompassing the following
parameters.
1) the type of grit material
2) the grit size
3) the bond strength of the wheel, commonly known as wheel hardness
4) the structure of the wheel denoting the porosity i.e. the amount of inter grit
spacing
5) the type of bond material
6) other than these parameters, the wheel manufacturer may add their own
identification code prefixing or suffixing (or both) the standard code.
