Bonded Abrasives Glossary

• Bonding Agent

  It refers to the material that holds abrasive grains together in a grinding tool. Bonding agents may consist of rubber, metal, or other material.

• Burr

  It means a rough edge that remains on metal after it has been cut or perforated.

• Chip

  A small particle of material that is removed during grinding, cutting, or abrasive processes.

• Chuck

  A clamping device that grips the post or shank of a mounted grinding tool.

• Closed Coat

  A dense arrangement of abrasive grains on a coated abrasive wheel or belt.

• Grinding

  The use of an abrasive to wear away at the surface of a workpiece and change its shape.

• Grinding Wheel

  A grinding tool made by bonding abrasive grits together and forming them into a circular shape.

• Honing

  A precision abrasion process in which a relatively small amount of material is removed from a surface by means of abrasive stones. The goal is to obtain a desired finish or extremely close dimensional tolerance.

• Honing Stone

  A finishing tool that may be hand-held or mounted. Honing stones are used to finish the interior of round holes as well as flat surfaces.

• Open Coat

  A more sparse arrangement of abrasive grains on a coated abrasive wheel or belt.

• Resinoid Bond

  An organic bond used in grinding tools that offers rapid stock removal and finer finishes.

• Rubber Bond

  An organic bond used in grinding wheels that offers smooth grinding action and fine finishing.

• Sand

  Loose, granular material derived from the crumbling of rocks.

• Shank

  The stalk or post on which a grinding tool is mounted.

• Shellac

  A bond material formulated from lac deposits made on tree twigs by the Indian lac insect. It is used to produce fine finishes on metal.

• Vitrified Bond

  A clay or ceramic bond characterized by its strength, rigidity, and resistance to oils, water, or temperature changes.
