Chamfering: Manual vs. Automated
Wednesday, July 5, 2017

Burrs naturally occur during the manufacturing process of gears. These burrs and rough edges can create hazardous conditions if they are not removed before use. They can cause damage to the machinery the gears are used in and harm to the machine operator if left unaddressed.  Chamfering and deburring is a process that removes the excess burrs and provides a smooth finish on gears.  There are a multitude of options for chamfering, and all of them serve their own unique roll.  Primarily though, there is a distinct difference between manual and automatic chamfering.

Simply put, manual chamfering is conducted with a chamfer tool.  It is labor intensive, not very cost effective, and the results are inconsistent because the work isn’t done in a mechanized, systematic way.  It can create safety issues for the laborer due to flying particles.  Manual chamfering can still be quite effective though, especially when you’re dealing with a company that has over 25 years of experience.  The manual approach is best used for low volume manufacturing or very large gears.

Automated chamfering is a reliable option for many manufacturers.  The automated machines still require operators, but the intensive labor and time to do the job is drastically reduced, therefore reducing overhead and increasing efficiency.   Skilled chamfering laborers can and will do an outstanding job chamfering manually.  However, the automated chamfering machines provide more consistency in gears produced.  Chamfering machines can also provide a product that meets specifications in a more precise manner.
