GRINDING WHEEL: Understanding Grit, Bond, Size and Application Before Selection

 

Selecting a grinding wheel only by its outside diameter can lead to the wrong choice.

A GRINDING WHEEL is made up of abrasive grains held together by a bonding system, and several characteristics influence how the wheel behaves during grinding.

Understanding a few basic factors makes wheel selection easier.

What Is Grit Size?

Grit describes the size of the abrasive particles in the wheel.

A coarse grit generally removes material more quickly.

A finer grit is usually selected where a smoother finish is more important.

This means the correct grit depends on the machining objective.

What Does the Bond Do?

The bond holds the abrasive grains together.

Its characteristics influence:

• wheel strength,

• grain retention,

• cutting behaviour,

• and wheel life.

The bond therefore needs to suit the grinding operation as well as the abrasive.

Why Does Wheel Size Matter?

Grinding machines are designed for particular wheel dimensions.

Before selecting a wheel, check:

• diameter,

• width,

• bore,

• spindle arrangement,

• and permitted operating speed.

Machine compatibility is a basic requirement, not an optional consideration.

Different Applications Need Different Wheels

Vermaent's current category illustrates how varied grinding requirements can be. It includes crankshaft grinding wheels up to 1200 mm diameter, cylindrical grinding wheels up to 200 mm width, roll grinding wheels up to 914 mm diameter, general industrial wheels and specialised valve and nozzle grinding products.

Crankshaft Grinding

Crankshaft wheels are used for journals, pins and bearing surfaces.

These operations require the wheel profile and specification to match the crankshaft-grinding setup.

Cylindrical Grinding

Cylindrical grinding focuses on the outside diameter of shafts and other round components.

The machine, material and desired finish all influence wheel selection.

Valve and Engine Rebuilding Applications

Engine rebuilding uses several specialised abrasive products.

These include:

• valve refacer wheels,

• valve-seat grinding stones,

• and valve-stem grinding wheels.

Different parts of the valve system need different grinding operations.

General Industrial Grinding

Some wheels are designed for broader machine-shop applications such as bench grinding, surface grinding and tool-room work. Vermaent also lists general industrial grinding wheels for such applications. (vermaent.com)

Conclusion

The correct grinding wheel is not chosen by one specification alone.

Material, grit, bond, dimensions, grinding operation and machine compatibility should be considered together.
