Most shops treat the deburr area as an entry level opportunity with entry level compensation. While some workers there will make it and demonstrate necessary skills, many do not. The ones with skills and ambition often aspire to, and attain, opportunities in the shop as machine operators and trainee machinists. This makes the deburr department a bit of a revolving door as far as retaining experience and skill.
Unfortunately, that is a common practice, specially for smaller shops where deburring operations do not warrant a full time position, therefore they will not offer a top notch salary for them.
And, then there are the ones where some manager sees the poor schmuck hunched over a buffing wheel or a dremel tool ( Heaven Forbid using a $1K+ NSK or Gesswein rotary unit ) wearing a face mask
and decides that anyone can do that job, therefore bottom shelf pay.
In both cases you WILL get what you pay for.
Fortunately though, for us small shops there are still plenty of business that are EXPLICITLY in the business of edge finishing, whatever that may entails.
I for one will program a part to dimensioned features, and may ( or may not ) program a simple 2D operation to knock off some heavy burrs.
I will program around and sort toolpaths so the heavy edges are machined to be manageable.
Otherwise, edge finishing is done by hand using whatever equipment is required by either internal people ( myself included ) or is outsourced to a professional house and then marvel at their work.
