Infeed value recommendations
Number of infeeds and total depth of thread.
Number of passes and size of infeed per pass
The recommended depths of cut for the different passes are shown
in the table below.
These are recommended as starting values - the most suitable
number of passes must be determined by trial and error.
Infeeds of less than 0.05 mm (0.002 inch) should be avoided
For Cubic Boron Nitride-tipped inserts, infeed should not exceed
0.10-0.12 mm (.004-.005 inch)
For multi-point inserts, it is essential that the correct infeed rec-
ommendations are used
For tables and recommendations see chapter 5, Technical refer-
ence (page 96) or use the Sandvik Coromant threading calculator
for more values.
