Many power-based grinding models exist, and most operators are familiar with Fred Bond’s “third theory”. Bond’s model is most commonly used to describe primary and secondary grinding to product sizes above, for example, 100 µm. Operators sometimes use Bond’s equation to describe grinding in situations where it is not appropriate, such as fine grinding below 50 µm. Using an ...

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size.

09-06-2005· My T & C won't do 20" planer knives, so I use a surface grinder. It's not ideal ot have the scratch pattern parallel to a sharp edge, but I hand hone knives after grinding to polish the edge anyway. I did what you did once, long ago, by making an arbor for the mill-drill, and using a 4" cup wheel. I rigged up a "sort of" guard around it with scrap.
