Detailed Product Description

Flank wear

 

  1. Rapid wear results in poor or out-of-tolerance surface quality.

 

Reason:

Excessive cutting speed

Insufficient wear resistance

Feeding too low

 

Solution:

Reduce cutting speed (VC)

Choose materials with higher wear resistance

Raise the feed (fz)

 

  1. Excessive wear leads to short tool life

 

Reason:

Vibration

Chip recutting

Burrs form on parts

Surface poor quality

generate heat

 

Solution:

Raise feed (FZ)

Adopt suitable milling

Use compressed air for effective chip removal

Check the recommended cutting parameters

 

  1. Uneven wear causes damage to sharp corners

 

Reason:

Tool run out

Vibration

Short tool life

Surface poor quality

loud noise

 

Solution:

Reduce the runout amount to less than 0.02mm

Check collet and collet

Minimize tool overhang

Use fewer teeth for cutting

Choose a larger tool diameter

For solid carbide end mills and replaceable head mills, select groove types with larger helical Angle (GP ≥45°)

Divide axial depth (AP) into multiple cutting knives

Reduced feed (FZ)

Improve tool and workpiece clamping

 

Crater wear

Excessive wear results in reduced cutting edge strength. A broken cutting edge results in poor surface quality
 

Reason:

The cutting temperature of the front blade surface is too high, which leads to diffusion wear

 

Solution:

Choose the alumina coating material

Choose the groove shape of front Angle blade

Lower the speed to get a lower temperature, and then lower the feed
