  • Grinding (abrasive cutting) - Wikipedia

    The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. [4] The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck , either electromagnetic or vacuum, and a reciprocating table.

  • Grinding machine - Wikipedia

    Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat. To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant. The coolant also benefits the machinist as the heat generated may cause burns. In high-precision grinding machines (most cylindrical and surface grinders ...

  • How It Works – Centerless Grinding Today’s Machining

    A bar of material, typically twelve feet long, feeds into the grinding machine between a grinding wheel and a regulating wheel. A carbide-tipped strip of steel, the work blade, supports the bar and holds it at the correct height, above the centerline of the grinding and regulating wheels. This is critical to the roundness and diameter tolerances of the bar. Both wheels rotate. The regulating ...

  • Machining Tolerances ChinaSavvy

    Assigned as boundaries for acceptable build, dimensional tolerances are assigned to parts, with acceptable degrees of variation set simply because no machines are capable of precisely holding dimensions. When it comes to tolerances, the main concern is how wide the tolerance is able to be without ultimately affecting other factors or the outcomes of the process.

  • Surface grinding - Wikipedia

    A machine vise (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold non-ferromagnetic workpieces if only a magnetic chuck is available. Factors to consider in surface grinding are the material of the grinding wheel and the material of the piece being worked on. Typical workpiece materials include cast iron and mild steel. These two materials don't tend ...
