Finishing process and deburring to yield beautiful product at any rate (How E.W is made)

Metal pieces feature acute angles at the corners and where they have been machined. It would be hazardous since you may cut your hand just by holding it. This would not function as a product either. Deburring is an important process for this purpose. This process is also required if you wish to polish the sharpened metal to resemble a mirror.

<Q&A>
・ What is deburring?
Deburring is the process of cleanly removing sharp corners and whiskers from the sharpened parts.

・What is finishing?
Have you ever been concerned about your car's dim headlights? But you can't do it yourself since you don't have a polishing machine. To polish it, a specific chemical is applied and a cloth-like item is turned by a machine. Finishing process in manufacturing is exactly the same with this.
