Burrs

Burrs are small, sharp pieces of metal that can become embedded in a tool or workpiece during machining operations. They can cause damage to the tool, the workpiece, or both. Burrs can also be a safety hazard, as they can easily cut skin or cause other injuries.

There are a number of different types of burrs, each with its own unique characteristics. The most common type of burr is a chip burr, which is formed when a chip of metal breaks off the workpiece and becomes embedded in the tool. Another type of burr is a tear burr, which is formed when the tool cuts into the workpiece too deeply. A gall burr is a type of burr that forms when the tool rubs against the workpiece in a way that causes the metal to become work-hardened.

Burrs can be removed from tools and workpieces using a variety of methods. The most common method is to use a file or a burr remover. Other methods include using a grinding wheel, a wire brush, or a chemical solvent.
