How2Day: Carbide Deburring Tools

One efficient way to give parts a clean edge or to reduce the size of a given part is to use a deburring tool. Deburring tools scrape components, sometimes with a very sharp knife, and other times by rotating at a high speed. Some deburring tools cut the edges of a particular object, while other deburring tools go into holes or cavities to cut the metal out.

Some parts have holes with remnants of metal on the edges that interfere with the proper functioning of the machinery. Some deburring tools spin and enter into the piece that is being worked on. The deburring tool blade is collapsed into the slot on the deburring tool. The top of the blade is a polished crown, preventing the bore from being marked when being fed through the hole. After clearing the back of the hole, the blade comes out. While spinning, the deburring tool scrapes away the stray pieces of metal. The deburring tool pressure can be adjusted, allowing the cutting pressure to be low or high. A locking screw can be unlocked to release the flex arm.

Some deburring tools scrape the edges off many materials so that they can be fitted into different pieces of machinery. These edge scrapers have blades that are in the form of hooks. These blades run along the edges of the part being deburred, scrapping the unnecessary material off of the part. Some of these deburring tools have larger and thicker handles for greater leverage when scrapping.

Radially-compliant deburring tools have bars that rotate 360 degrees. A spinning cutting bit is attached to the tip of this rotating bar. The bit has grooved edges, allowing the tool to scrape the edges of the part being deburred. This tool often is powered by compressed air. Air-powered deburring tools are more environmentally friendly because they do not release harmful exhausts. These deburring tools have different rotations per minute. The rotations per minute range from 30,000 to 65,000.
