  • Grinding wheels are one of the tools for machining or machining or machining workpieces with geometrically indeterminate bonded grain cutting edges.
  • a central coupling area typically a steel ring, a bracket or simply a hole
  • the grinding wheel is mounted on the spindle or drive shaft of the rotary drive of a portable, hand-held or fixed grinder.
  • the grinding wheel thus carries out a rotating main movement about an axis of rotation extending through the central coupling region.
  • grinding wheels are characterized by the abrasive (abrasive grain), grain size, hardness, microstructure and bond.
  • the cutting elements distributed on the working surface of the grinding wheel separate a large number of small chips from the workpiece surface at a very high speed.
  • grinding regions or grinding surfaces outside the coupling region can be arranged on a flat side perpendicular or oblique to the axis of rotation and / or on a narrow side on the circumference of the grinding wheel.
  • inclined grinding surfaces can also be used, for example in the case of the so-called fan or disk grinding wheels.
  • the grinding wheel can be used in particular for separating and is then also called cut-off wheel or short cutting disc. Grinding is widely used in the tool manufacturing industry, in the automotive industry, engine and transmission construction, in the rolling bearing industry, as well as in virtually all branches of the engineering industry.
  • Abrasive wheels may be made by adhering, e.g., adhering, the abrasive material, eg, abrasive paper or abrasive nonwoven, to a backing, and / or embedding abrasive grains in a backing matrix, e.g., made of synthetic resin, e.g. with cobalt as grinding material, or also of metal or a metal alloy, e.g. with diamond as abrasive material.

Furthermore, this can reduce the transmission of vibrations to the machine, so that the stress of the machine parts can be reduced and thus the life of the machine can be increased.
