Issue description Possible causes Proposed solution
Burns
  • working layer of the grinding wheel is taped

  • low grinding power

  • excessive crossfeed or infeed

  • ineffective cooling (wet grinding wheels)

  • grinding wheel is too hard
  • dress the grinding wheel by use of a ceramic whetstone

  • increase the grinding power, decrease the feed

  • decrease the excess

  • improve the efficiency of cooling

  • replace the grinding wheel with a softer one or such characterised by a lower grit concentration
  • Low durability, quick deformation
  • grinding wheel is not sufficiently hard

  • grit concentration is too low

  • ineffective cooling

  • perimeter speed of the grinding wheel is too low

  • grinding wheel is not balanced

  • grinding wheel is not cylindrical

  • vibrations in the kinematic system of the grinder
  • increase the hardness

  • increase the grit concentration

  • improve the efficiency of cooling

  • increase the perimeter speed of the grinding wheel

  • balance the grinding wheel

  • align the grinding wheel

  • decrease the machining parameters, order the grinder inspection
  • High roughness of the surface being ground
  • grit dimension is too big

  • ineffective cooling (soiled coolant)

  • perimeter speed of the grinding wheel is too low
  • use grinding wheel with finer grit

  • improve the efficiency of cooling
