Chamfering and Deburring Gears Precisely
Gears need to be Chamfered and Deburred with a controlled, high quality process for the following areasons:
· To avoid breakage – Excessive carburizing along the tooth edges can often cause breakage when the gear is running
· To avoid damaging gears and bearings – If burrs are not removed, they may chip off during the running cycle and cause damage to the other gears and bearings.
· To avoid poor tool life in the finishing processes
· Removal of very sharp burrs reduces the risk of tool handling injuries

Gear with Big Burr
Chamfering Specified on Gears is of following types: in only one or in both flanks, with a constant size along the profile, with or without chamfer in root diameter. Sometimes a further Rolling Operation is required (refer section on Rolling below)
