Guide for Internal Threading
For the internal threading, pay extra attention to “Stabilizing Bore Dia.” and “chip evacuation”.
1 “Stabilizing Bore Dia.”
Because small pitch internal threading has small corner-R(r), there is variation in the Bore Dia. which may greatly inuence the tool life of an insert.
In order to eliminate the variation in the Bore Dia., “0” cutting (zero cutting) should be performed as the zero pass, before the rst pass in threading.
The Bore Dia. is cut with the specied dimension, and the rst pass of threading becomes stable.
2 “Chip evacuation”
If cutting process is continued when chips are tangled with a holder and other parts of the machine, it may cause damages to the insert. Therefore,
please ensure that there are no tangled chips in the machine by the following method.
Set the program with the “single block”.
Keep the threading starting point 50mm~100mm away from the side of workpiece,
and conrm that coolant is ushing down the chips for each pass.
Ensure that chips are not tangled; then start the continuous run.
