Boring troubleshooting tips for both rough boring and fine boring, concerning chip breaking, tool vibrations and machine power limitation, are presented below.
Rough boring troubleshooting
| Cause | Solution |
|---|
|
Chip breaking
Chips too short and hard
 | - Feed too high
- Cutting speed too low
- Unsuitable geometry
| - Decrease feed
- Increase cutting speed
- Change geometry to a more open chip breaker
|
|
Chip breaking
Chips too long
 | - Feed too low
- Cutting speed too high
- Unsuitable geometry
| - Increase feed
- Decrease cutting speed
- Change geometry to a more closed chip breaker
|
|
Tool vibration
 | - Tool length/coupling size ratio too high
| - Use largest possible coupling size
- Use/shorten the dampened boring tool
|
| | | | |
| - Ensure rigid clamping with face contact to spindle
- Use rough boring tool with a two-insert design
- Check that all units in the tool assembly are assembled correctly, with correct torque
- Check machine spindle, workpiece clamping, wear, etc.

| |
| - Decrease depth of cut
- Use positive inserts
- Use smaller nose radius
- Wiper inserts not recommended for long overhangs or unstable conditions

Machine power
 | | - Make sure the machine can provide the required torque and power for the specific boring application, especially when rough boring
- Decrease cutting data
- Apply step boring
