Indexable inserts - Types of wear and solution proposals
Built-up edges
 Select cutting material types with less friction
resistance
 Increase the cutting speed
 Increase the feed
 Do not use water-soluble coolant
 Check coolant use
 Check indexable insert classifi cation
 Check chip breaker selection
 Increase clearance angle
 Reduce chamfer and rounding of cutting edge
Brittle damage to the cutting edge
 Use tougher cemented carbide type
 Select less intensive cutting conditions
 Apply diff erent cutting edge geometry
 Reduce feed when inserting into opening
Scour wear
 Select harder cutting material
 Reduce cutting speed
 Reduce feed
 Reduce cutting depth
 Check coolant use
 Check chip breaker selection
 Increase clearance angle
Oxidation gouging on secondary cutting edge
 Apply coated or wear-resistant cemented carbide
types, if possible apply coated indexable inserts
with AI2O3 content.
 Apply cooling emulsion or Increase cooling
intensity
 Reduce cutting speed
Notch wear on main cutting edge
 Apply coated or wear-resistant cemented carbide
type, if possible apply coated indexable inserts
with AI2O3 content.
 Use tool with a smaller adjustment angle
 Distribute chip unevenly
Breaking of cutting edge
 Select tougher cutting material
 Select cutting material type less sensitive to
temperature fl uctuations
 Reduce feed
 Reduce cutting depth
 Check chip breaker selection
 Increase size of chamfer and rounding of cutting
edge
 Select machine with higher performance and
rigidity
