Burr (edge)

A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process.

Burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or turning.

[3] Burrs can be minimized or prevented by considering materials, function, shape, and processing in the design and manufacturing engineering phases of product development.

Burrs cause more stress to be concentrated at the edges of holes, decreasing resistance to fracture and shortening fatigue life.

Burrs in holes also increase the risk of corrosion, which may be due to variations in the thickness of coatings on a rougher surface.

The chamber is then evacuated of air and filled with an oxygen and fuel mix; this mixture is pressurized to 0.5 to 1.9 MPa (73 to 276 psi).

[8] Common materials that are typically cryogenically deburred with blast media include PEEK, nylon, Teflon, Delrin, polypropylene, polycarbonate, acetal, PTFE, PET, HDPE, PVC, ABS and many others.

[11] One of the main benefits of waterjet deburring is a high level of precision and repeatability - and for this reason, CNC control is used.

This eco-friendly process uses high-pressure water to remove loose burrs and chips even in deep holes – all while leaving the parts cleaner and free of debris.

Pressurized water is precisely focused via CNC control to remove burrs and chips in and around parts.
