Chisel Chipping Built-up Edge

Cause Cause
• Chisel run-out is too big • Cutting zone temperature is too low
• Combine of high feed and low speed • Negative cutting geometry
Remedy • Machining of very sticky materials such as low-
• Reduce feed rate and increase the cutting speed carbon steel, stainless steels, and aluminum
• Check that chisel misalignment does not exceed 0.02 mm Remedy
• Check tool and part clamping rigidity • Increase the feed
• Check if pocket gripping forces are too • Increase cutting speed
low - if so, replace the holder • Increase coolant pressure
• Check oil percentage in the coolant fluid

Plastic Deformation Crater Wear

Cause Cause
• Cutting temperature is too high • Excessive cutting temperatures and
Remedy pressures on the top of the insert
• Check cutting parameters Remedy
• Reduce cutting feed • Reduce cutting feed
• Increase coolant pressure/volume • Check that the correct geometry is used
• Use harder grade
• Check that the correct geometry is used

Thermal Cracking Flank Wear
Cause Cause
• Excessive variations in surface temperature, • High cutting speed
intermittent machining, or variations in coolant supply • Low wear resistance carbide grade
Remedy Remedy
• Increase coolant pressure/volume • Check that the correct geometry is used
• Increase oil concentration percentage • Increase coolant pressure
• Change to harder grade
• Increase oil concentration percentage
• Reduce cutting speed and increase feed
