Flexibility with possibility to choose from three different tool set-ups
Long reach length up to 6 x D
Application
Boring operations: roughing and finishing
Cutting data can be increased substantially thanks to eliminated vibrations
Productivity increase from 4 x bar diameter
Recommendations
The entering angle should be close to 90 degrees to give more axial cutting forces and less radial/tangential forces.
Use large entering angles and small nose radii to reduce the radial forces, deflection and vibrations.
Small nose radius is ideal for small depths of cut and decrease the risk of vibrations. Large nose radii have strong edge security and allow for heavy feeds and large depths of cut. The risk of vibration gets higher the larger nose radius you use. Therefore, triangular, positive style inserts are first choice for dampened boring operations.
Use as light cutting units as possible to improve the dynamic behavior and effect of the damper.
If possible, use a tapered shank
Productive boring: Two inserts with the same length and diameter to be able to increase feed
Step boring: Additional shim under one of the slides if you want to take a large radial cut
Single-edge boring: Replace one of the slides with a cover to reduce cutting forces and achieve accurate roundness, good surface finish and close tolerances
