If you’re regularly working with machine parts, then you’ve surely come across unwelcome irregularities in the form of burrs. These deformities can be very annoying to deal with, on top of reducing the safety and functionality of each affected piece.
It’s important for you to have these burrs removed in order to smooth out the machine parts for quality assembly.
Deburring is a process in which the imperfections that are known as “burrs” are systematically removed from machine metal parts. There are different types of deburring processes that can remove these burrs— all of which result in smoother, more reliable metal products.
But What Causes a Burr?
The machining process in general commonly produces these pesky defects known as burrs. Burrs are typically formed during any of these following stages of machining:
- Laser cutting
- Waterjet cutting
- Plasma cutting
3 Main Types of Burrs
The formation of a burr usually takes one of these types:
- Poisson burr: These occur when metal over-accumulates at the end of a piece, extending sideways.
- Rollover burr: The most common type of burr, this looks like a tiny piece of curled metal popping out of the part.
- Breakout burr: These have a distinguishable upswelling form, making them appear like they’re breaking out of the piece.
