As my previous article of Grinding Machine, I told, grinding is an important operation in manufacturing industry to get a final product, so for that, we need to know about the grinding wheel and its properties so that we easily choose a right wheel for the right material.
So hello viewers in today's article you learn about the definition, types, grain, grade, structure, bond, specifications, and selection of a Grinding wheel. Also at the end of the article, I give you PDF downloadable link. So let's begin...
Artificial Abrasive (Synthetic diamond, Tin oxide, Aluminum oxide, Silicon Carbide)
Superabrasives make up a special category of bonded abrasives designed for grinding the hardest, most challenging work materials.
Because carbides, high-speed steels, PCD, PCBN, ceramics and some other materials used to make cutting tools can be nearly as hard as conventional abrasives, the job of sharpening them falls to a special class of abrasives-diamond and the CBN, the super-abrasives.
These materials offer extreme hardness, but they are more expensive than conventional abrasives (silicon carbide and aluminum oxide). Therefore, super-abrasive grinding wheels have different construction than conventional abrasive wheels.
Types of Grinding Wheels:
In general, there are 10-types of grinding wheel available in the market and those are:
Factors affecting the selection of Grinding wheels:
Proper grinding wheel selection is essential to ensure that the required
Production rate, and
The overall cost per part is achieved.
It is normally depends upon several terms like:
The type of grinding operation we performed
Grinding machine condition
Requirement of surface finishing
Shape and size of a workpiece
Work piece material.
Difference between cutting wheel and Grinding Wheel?
In the grinding wheel, there is term Abrasive which we studied, it provides surface finishing helps to get good surface finish of the workpiece and also provides good luster.
The grinding wheel has good strength which avoids cutting improper shape and size.
The normal cutting tool doesn't have abrasive. So it will not provide better finishing accuracy as grinding wheel provides.
The chances of wear and tear are high in cutting wheel
A grinding wheel having low chances of wear and tear.
Price of a grinding wheel is more
The price of the cutting wheel is less than grinding wheel.
Detailed video lecture on Grinding wheels:
Let's see how a grinding wheel is made?
And now let's see an experiment
Hola! now you are pro on selection of a grinding wheel, right? I hope you understand the definition, types, grain, grade, structure, bond, specifications, and selection of a Grinding wheel well and never forget in the future.

In this article, I'm going discuss about Steam Condenser in briefly. At the end of this article, you will learn How a Steam Condenser works, Definition and Types of a steam condenser, and more. So let's get started. The Functions or Needs of a Steam Condenser: The functions or the needs of the condenser in […]
Today in this article I am going to give you an in-depth overview of Electron Beam Welding Machine. This Welding Process was first developed in 1949 by Karl-Heinz Steigerwald who was a German physicist. In this article first, we will see the Definition, How it's Work after that I'll also show you the Applications, Advantages, […]
In the field of mechanical engineering, the Extrusion Process is widely used by the engineers to form an object which has a fixed cross-sectional area. For making the object, the raw material is pushed into a die to provide it with the desired shape. The major function of this process is that the brittle materials […]
