  2. Grinding wheel wear - Wikipedia

    en.wikipedia.org/wiki/Grinding_wheel_wear

    The quality, characteristics, and rate of grinding wheel wear can be affected by contributions of the characteristics of the material of the workpiece, the temperature increase of the workpiece, and the rate of wear of the grinding wheel itself. Moderate wear rate allows for more consistent material size. Maintaining stable grinding forces is ...

  3. Grinding wheel - Wikipedia

    en.wikipedia.org/wiki/Grinding_wheel

    Grinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface. Trueing the wheel makes the grinding surface parallel to the ...

    en.wikipedia.org/wiki/Centerless_grinding

    A schematic diagram of the centerless grinding process. Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. [1] Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; [2] the workpiece is secured between two rotary grinding wheels, and the speed of their ...

    Grinding wheel on a grinding machine. Excessive spindle speed will cause premature tool wear, breakages, and can cause tool chatter, all of which can lead to potentially dangerous conditions. Using the correct spindle speed for the material and tools will greatly enhance tool life and the quality of the surface finish.

  6. Tool wear - Wikipedia

    en.wikipedia.org/wiki/Tool_wear

    glazing occurs on grinding wheels, and occurs when the exposed abrasive becomes dulled. It is noticeable as a shine while the wheel is in motion. edge wear, in drills, refers to wear to the outer edge of a drill bit around the cutting face caused by excessive cutting speed. It extends down the drill flutes, and requires a large volume of ...

  7. Wear coefficient - Wikipedia

    en.wikipedia.org/wiki/Wear_coefficient

    Traditionally, the wear of materials has been characterized by weight loss and wear rate. However, studies have found that wear coefficient is more suitable. The reason being that it takes the wear rate, the applied load, and the hardness of the wear pin into account. Although, measurement variations by an order of 10-1 have been observed, the ...

    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.
