4. Boring
Rough boring
Choose a roughing geometry unless a small depth of cut is needed.
For smaller cutting depths, use a medium geometry. Recommended
nose radius: 0.8 mm (0.031 inch) and if you experience problems,
try 0.4 mm (0.016 inch). For severe problems, try to use only one
insert.
With Sandvik Coromant dampened rough boring tools three
diffe rent tool set-ups are possible:
• Productive boring: two inserts with the same length and diameter
• Step boring: Additional shim under one of the slides
• Single-edge boring: Replace one of the slides with a cover
