Managing Grinding Forces and Abrasive Sharpness | Modern ...

When using vitrified or metal-bonded grinding wheels, these resistance forces lead to fracturing of the abrasive grain from the bond. In the case of organic- and resin-bonded wheels, the heat produced from the grinding interaction releases dull abrasive grains over time, exposing the new sharper grain beneath it.

Robotic Grinding & Automated Material Removal Applications ...

For example, if the operator applies too much force the abrasive media glazes over. Conversely, the abrasive will not re-fracture if too little force is applied. With an automated system, not only is the part quality significantly better, but abrasive life can increase by 200-300%.

TYPES OF GRINDING MEDIA - energosteel

For example cylpebs of "gray" cast iron is soft enough and as result an increase in specific consumption of grinding media in the grinding process. Cylpebs production of "white" cast iron is very expensive and this caused by the high cost of the chemical elements that are part of the "white" cast iron. So what is better, a ball or a cylpebs?
