Common Application Problems
Loading. Filling of the pores of the Glazing. Extreme condition of loading
grinding-wheel surface with the on a grinding wheel. Caused by dull
material being ground. Often results in abrasive grain and a resin buildup that
decreased cutting rate and poor finish covers the grain.
• The wheel can be dressed to • The wheel can be dressed to
remove the loading temporarily. remove the glaze temporarily.
• To prevent loading, select a wheel • To prevent glazing, select a softer
