Related Glossary Terms

  • abrasive

    abrasive

    Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

  • alloys

    alloys

    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • grinding

    grinding

    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • grit size

    grit size

    Specified size of the abrasive particles in grinding wheels and other abrasive tools. Determines metal-removal capability and quality of finish.

  • hardness

    hardness

    Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.

  • shank

    shank

    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

Vitrified- and Resin-Bond Mounted Points

PFERD offers an extensive line of vitrified- and resin-bond mounted points designed to meet an array of application needs for use in both surface and edge grinding. The mounted points can be used on a variety of materials from stainless steel and cast iron to exotic alloys.

To meet these varied needs, PFERD mounted points come in a broad range of grain types, grit sizes, bond harness and shapes. They provide high-stock removal rates, high-edge holding, dimensional stability and cool grinding to reduce the thermal load on a workpiece.

PFERD mounted points are available in a variety of abrasive grains and blends, including ceramic-oxide mounted points, designed for use in aerospace applications.

PFERD mounted points are manufactured to exacting standards of dimensional accuracy and stability, consistent quality and close tolerances.

In addition to industry standard shapes, for specific requirements PFERD can customize its mounted point shapes and offer special bonds and variations in hardness, grit size and dimension. A range of shank extensions are available, making it easier to work in hard-to-reach areas such as inside castings and pipes.
