Overheated edge BESS scores

[scott.livesey]

Somewhat cautious in naming  brands here...  that is ok, just guessing that the brands are the same ones I would see at a industry supply store here in US
Scott, like Grepper said I would be obliged if you could point to the overheating studies you mentioned.
Coarse grits are less likely to cause overheating, but I am looking at somebrand SM-111 that has 200 grit coarse wheels running wet at 250 RPM, when its honing wheels run dry at 800 RPM, plus a felt buffing wheel - does this renown sharpening machine maker recognize the overheating, or we see the issue where there is none?  they do recognize the issue which is why they run the wheels wet.  the felt buffing wheel you found heated the blade more than your paper wheel
And if we find out that they knowingly ignore facts known since 1930, how can we name their brand/company here?

As one would expect from a company in this day and time, efficiency is king.  
it sounds like each person cutting has access to three steels and is trained on which steel to use depending on condition of the knife.  do the cutters use the same knife every day or do they just pick one up at start of shift?  do they change knives after the 5 hour period or was that just your time there.  or do the knives get resharpened while they have meal break?
there are several very large pork and chicken processing plants nearby, but getting access is harder than getting access to military base. 
i have not come up with exact numbers on how to NOT overheat.  you can sense overheating by keeping a finger on the back side of the blade while grinding or by seeing sparks or by noticing color changes in the steel.  on my grinder I finish with fine(220 zirc or P220 ceramic) belts at about 350 SFPM, wet.  I also use a disc sander with very fine(400 to 1200 silicon carbide) discs at about 300 rpm.  once I have an edge that easily slices copy paper, I go to a fine Norton India, then Smith's 750 diamond, then JewelStik 1200 diamond.
