  2. Grinding wheel - Wikipedia

    en.wikipedia.org/wiki/Grinding_wheel

    Grinding wheel. Grinding wheels are wheels that contain abrasive compounds for grinding and abrasive machining operations. Such wheels are also used in grinding machines. The wheels are generally made with composite material. This consists of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in ...

  3. Electrochemical grinding - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_grinding

    Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. [1] Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but ...

  4. Surface grinding - Wikipedia

    en.wikipedia.org/wiki/Surface_grinding

    Surface grinding is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose. The components of a surface grinding ...

  5. Spark testing - Wikipedia

    en.wikipedia.org/wiki/Spark_testing

    In either case, the grinding wheel must have adequate surface velocity, at least 23 m/s (4500 surface feet per minute (sfpm)), but should be between 38 and 58 m/s (7500–11,500 sfpm). The wheel should be coarse and hard, therefore aluminium oxide or carborundum often are employed. The test area should be in an area where there is no bright ...

  6. Abrasive - Wikipedia

    en.wikipedia.org/wiki/Abrasive

    Abrasive. An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing [1] which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded ...

  7. Grinding dresser - Wikipedia

    en.wikipedia.org/wiki/Grinding_dresser

    A grinding dresser or wheel dresser is a tool to dress (slightly trim) the surface of a grinding wheel.Grinding dressers are used to return a wheel to its original round shape (to true it up), to expose fresh grains for renewed cutting action (including cleaning away clogged areas), or to make a different profile (cross-sectional shape) on the wheel's edge.
