The invention is used in cars, cylinder heads of internal combustion engines, and in cylinder heads of internal combustion engines having three gasoline cylinders.

The invention is used in cars, cylinder heads of internal combustion engines, and in cylinder heads of internal combustion engines having three gasoline cylinders.

More particularly, the invention concerns internal combustion engine cylinder heads.

Transportable device for grinding petrol or Diesel engine cylinder heads.

The invention also relates specifically to supercharged diesel or gasoline internal combustion engine cylinder heads.

In particular, the invention relates to cylinder heads of supercharged diesel or petrol internal combustion engines.

The above is applied to improving the machinability of pieces such as cylinder heads for internal combustion engines whilst retaining good durability.

The invention also concerns a transportable device for grinding (surfacing) petrol or Diesel cylinder heads when the engine has been removed.

The above is of application in the transition region between pressure supports and channel walls in cylinder heads, for example.

By way of example, Sandvik Coromant recently proposed the testing and implementation of CoroMill® 5B90 to machine the combustion face of cylinder heads and overcome excessive burr.
