Internal cylindrical grinding – precision from the inside out

Before the workpieces and parts make their final journey to our customers, they must be perfect not only on the outside, but also on the inside. This is where internal cylindrical grinding comes in.

But how exactly does internal cylindrical grinding work?

In internal cylindrical grinding, a grinding wheel moves into the bore. The aim is to produce the bore with precise dimensions and surface quality (e.g., cylindrical or conical). Both the workpiece, which is clamped in the chuck, and the grinding wheel rotate in opposite directions.

This makes the grinding process perfectly suited for machining even larger bores and is most commonly used for die shells, upsetting dies, and head discs, for example.
