For internal grooving, the machining methods for external grooving (F107–F108) can be used, but please note the following precautions.
Supply large amounts of coolant for effective chip disposal during cutting. Maintain supply until the tool has been retracted completely for improved ship disposal.
As continuous chips tend to elongate at the back of the bore, the above operation is recommended.
The recommended width of cut for (2) is 0.5mm.
It is recommended to carry out grooving from the front end of the workpiece.
This reduces workpiece deflection.
