Glossary


Brush – the use of nylon abrasive filaments or wire to create a smooth, rounded finish on surfaces and edges.

Bur – the bit / cutting tool that is placed in the collet of the deburring tool that actually cuts away the burr. To purchase, see our Partner list.

Burr – the often undesirable piece of metal, plastic, fiberglass, etc. left behind as a result of machining, forging, casting, or molding processes.

Cast – process by which a liquid material is poured into a mold which contains a hollow cavity of the desired shape and then allowed to solidify. The solidified part is known as a casting which is ejected or broken out of the mold to complete the process.

Chamfer – the removal of material to create a beveled edge.

Compliant – device’s ability to radially deviate from a known center position with a constant, controlled resistance force.

Deburr – the removal of rough or sharp edges from a part.

Deburring Tool – RAD’s automated tool with either a variable-speed electric or air motor.

Deflash – the removal of flash or parting lines from forging, casting, or molding operations.

Degate – the removal of gates – where molten material is injected into a mold.

Finish – the process of improving surface quality and eliminating edge roughness. Finishing is a necessary step requiring skilled labor in often poor work environments (dirty, loud, and/or dangerous). Finishing operations generally take place when parts are nearly completed – making scrapped parts very costly.

Forged – shaping metal by using localized compressive forces.

Grind – the process of cutting using an abrasive wheel as the cutting tool.

Machined – when power-driven machine tools, such as lathes, milling machines, and drill presses, are used with a sharp cutting tool to mechanically cut the material to achieve the desired geometry.

Molded – shaping pliable raw material using a rigid frame or model called a pattern.
