The spark generated by this process produces heat, which remove metal by erosion and evaporation.

  • 8 Principles of Centerless Grinding Metal Cutting

    Dec 08, 2016· A downside of centerless grinding is you can’t have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That’s why we like to say that where machining ends, the centerless grinding process begins.

  • Grinding (abrasive cutting) Wikipedia

    Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

    SummaryOverviewTypesSee also

    A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracyof shape and dimension. As the accuracy in dimensions in grinding is of the order of
