How Does A Grinder Machine Work?

Why do grinding wheels explode?

Grinding operations generate tremendous amounts of heat.

This heat causes expansion and if foreign materials are embedded in the stone then the differential rate of thermal expansion between the two materials can cause a wheel to shatter..

What is a primary difference between surface grinding and cylindrical grinding?

Surface grinding cuts a flat, cylindrical grinding cuts a round. You can use the same media on both processes. One other note – you typically mount a cylindrical part between centres or in a collet. For surface grinding you need a magnetic chuck or you need to wax the parts.
