Sandvik Coromant – How to reduce vibration in metal cutting 13
Inserts:
First choice is the all round geometry the GC 1020 for the ISO P, M and
K areas. F geometry with its sharp cutting edge is suitable for more tricky
materials and C geometry for reliable chip breakage.
Threading applications:
When threading it is possible to change the programme in order to mini-
mize the risk of vibration. By modifying the flank infeed, the axial cutting
forces will increase, which will also reduce any vibration.
Rounded (ER treated) cutting edge
First choice in most operations and
materials
Example: R166.0G-16MM01–150
Geometry F
Sharp cutting edge
Reduced cutting forces and good
surface finishes
Example: R166.0G-16MM01F150
Geometry C
Chip breaking geometry
For maximum chip control and
minimum supervision
Example: R166.0G-16MM01C150
