The effects of ball milling and cryomilling on sulfamerazine forms I and II SMZ FI FII were investigated using X ray powder diffraction infrared and near infrared NIR spectroscopy Cryomilling resulted in a complete amorphization of both polymorphs Milling at room temperature gave mixtures of amorphous SMZ FA and FII.
In milling operations conducted using circle segment end mills the resulting cutting conditions are generally different from the point contact which occurs in milling with ball end mills As a result there may be significant variations in the machinability criteria such as cutting force tool wear process stability and surface quality.
Three centuries ago an astonishingly simple manufacturing method had been developed for balls made of stone e g marble Figure 33 left Lumps of stone were hammered into squares with rounded edges and put on stone plates with concentric grooves then a wooden plate was put on top and run as a water wheel until after one two or three.
