Troubleshooting

12 tips to help diagnose problems

• excessive honing of cutting lip
• reduce cutting lip honing
• bright finish cutting lip
• have tool coated

Crumbling of outer corners non rigid conditions, insufficient workpiece rigid clamping of workpiece

clamping

• deviation from concentricity too large
• check and correct concentricity if possible
• interrupted cut
• reduce feed

Heavy wear at flank cutting speed too high reduce cutting speed

• feed too low
• increase feed
• clearance angle too small
• increase clearance angle

Crumbling on cutting lips non rigid conditions, insufficient workpiece rigid clamping of workpiece

clamping

• interrupted cut
• reduce feed
• max. wear values exceeded
• reduce tool change intervals
• incorrect tool type
• apply suitable tool

Land wear non rigid conditions, insufficient workpiece rigid clamping of workpiece

clamping

• deviation from concentricity too large
• check and correct concentricity if possible
• back taper too small
• increase back taper
• incorrect coolant (oil), coolant too weak
• increase strength of coolant or use neat oil

Scoring on tool body non rigid conditions, insufficient workpiece rigid clamping of workpiece

clamping

• deviation from concentricity too large
• check and correct concentricity if possible
• interrupted cut
• reduce feed
• abrasive workpiece material
• increase strength of coolant or use neat oil
