| 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
