  • Types of Plastic Burrs and Deburring ProcessesCraftech

    A burr (also known as a "flash") is an unwanted raised edge or small piece of material left after a part has been worked in a manufacturing process. It can be metal rubber plastic or really any other material used in manufacturing. Machining operations such as grinding drilling milling turning tapping slotting etc. cause burrs in machining operations. As you can see in the picture
