### Grinding wheel wearWikipedia

Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. The grinding process itself has been compared to machining operations which Grinding Wheel Quality The quality of grinding wheel performance is related to the specific conditions of a given application such as type of machine and composition of workpiece and is evaluated according to two criteria G-Ratio and Efficiency. 1) G-Ratio or Grinding Ratio In grinding applications this is the ratio of the weight of material

### Optimizing grinding and dressing with dressing speed

Jun 04 2018 · The dress speed ratio is the relationship between the dress roll velocity (V r) in sfm or m/sec and the grinding wheel velocity (V s) in sfm or m/sec. and can be calculated using the following equation Speed ratio = V r ÷ V s The dress speed ratio can be a positive or a negative value as shown in Figure 5. The grinding ratio of a CBN wheel can often be as much as 200 times greater than that of an aluminum oxide wheel and in many cases after initial wheel preparation may require no additional maintenance for the life of the wheel. CBN cuts an impressive swath This grinding ratio is a comparison point or a measure of efficiency.
