Why chamfer and deburr?

Chamfer Deburr Process Explained

  • A burr which is not removed may break off during use and damage bearings or gears in gearboxes.
  • Over-carbonizing may result in too much pressure being exerted on sharp gear lateral surfaces which might then break.
  • A hardened burr may lead to premature wear of tools in subsequent finishing operations.
  • Removal of very sharp burrs reduces the risk of tool handling injuries.

Why roll?

  • The rolling operation serves to remove the material that builds up on the tooth flanks by plastic deformation during chamfering.
  • During chamfering/deburring, structural material changes in the form of compression may occur. The rolling process levels out the surface and causes the material to sink.

Chamfering Tools

Chamfering the flank edges of spur and helical cylindrical gears prevents edge distortion during heat treatment and protects the tooth profile against any nicks that may occur during handling.
