Deburring

Rolled Burr: This type of burr is formed when material is pressed upward and outward, usually during the thread-rolling process. Rolled burrs tend to be smoother and less sharp than other types.

Tear Burr: Tear burrs result from shearing or cutting operations, where the material is deformed and separated along the cutting edge. These burrs can be irregular and jagged.

Breakout Burr: Breakout burrs occur in materials like composites, laminates, and plastics. When the cutting tool exits the material, it can cause a breakout burr, which resembles a flaked edge.

Edge Burrs: Edge burrs occur along the edges of a workpiece during processes like shearing or punching. They can be sharp and irregular, potentially posing safety hazards.

Sliver Burr: Sliver burrs are thin, elongated burrs that can result from various machining processes. They are usually narrow and can extend from the edges of a workpiece.

Micro Burr: These are extremely small burrs that may not always be visible to the naked eye. They can form during micro-machining or precision manufacturing processes and can affect the functionality of micro-components.

Cross-Drilled Burr: Cross-drilled burrs are produced during drilling operations, where a burr forms on the exit side of the hole. This type of burr can interfere with fastener insertion and weaken the material around the hole.

Undercut Burr: Undercut burrs are formed when the cutting tool digs below the intended surface, creating a recess or undercut. These burrs can be problematic in applications where a flush or level surface is required.

Split Burr: Split burrs occur when a workpiece cracks or splits along its edge, resulting in a raised burr. This can happen during cutting or machining of brittle materials.
