A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. [1] It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring .

2015年1月11日 · Edge view of a burr raised by repeated strokes of one side of the blade on a DMT 1200 diamond plate. This burr is easily felt by brushing a finger across the edge. A cross-section was cut into the edge through the burr.

A burr (also called a wire edge) is a little ridge of metal that is pushed over the apex of the edge. The burr is your assurance that you've reached all the way to the apex of your bevel and will be able to create a truly sharp knife.

2023年8月22日 · Different types of burrs are produced by different processes and machining conditions. Rollover burrs (or exit burrs) form on the exit side of the machining process as the material rolls with the tool, is pushed over an edge and is retained. The thickness of these burrs will depend on the depth of cut.

2023年2月16日 · A burr is a raised edge or small piece of material that is formed from a modification process and remains attached to the edge of a workpiece. Created by machining processes, such as slitting, burrs are frequently removed as these exposed sharp edges can be dangerous to handle and add difficulty to fabrication in some manufacturing situations.

2015年1月13日 · In the typical honing progression on a flat hone with edge leading strokes, alternating sides, a triangular bevel is formed, terminating at a width determined by the level of “micro-chipping” that occurs at the apex. A burr, as defined by “metal beyond the apex” does not form; the raised-burr is easily avoided.

2006年3月7日 · Burr is an edge defect that can arise during slitting. The primary cause of burr is a horizontal knife clearance that is too tight or too loose. An incorrect clearance automatically causes a poor-quality edge.

Burr is a rough remainder of material outside the ideal geometrical shape of an external edge, or a residue of machining or of a forming process (Fig. 22.1). Undercut is a deviation inside the ideal geometrical shape of an internal or external edge (Fig. 22.1).

A burr is a raised metal edge formed on the cut surface during shearing and hole punching using a press. Burrs are also known as "flash". Contact with burrs left on an edge can injure the person’s hand. Burrs can also hinder correct assembly and joining. To prevent these problems, burrs should be removed by polishing the edges.

A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring. Burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or turning.
