اقرأ أكثرAlso your type of wheel you are using, the wheels surface condition and also the size of wheel will have a impact of surface speed of grinding. Your table feed will have a smaller effect on surface finish compared to many other factors described above. Factors such as spindle condition, use of coolant and depth of cuts will have a greater effect.
اقرأ أكثرGrinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.
اقرأ أكثرTo move grinding wheel speeds into the ultra-high speed grinding (UHSG) regime (above 40,000 fpm or 200 m/sec), the wheel core must be made of metal, and the abrasive is likely to be plated. Such wheels can run at nearsonic speeds (66,000 fpm or 335 m/sec) without the fear of bursting.
