your wheels are good
they are run on Coborn RG5 and Ewag grinding machines.
We run at 1300 / 1400 rpm
But generally I am happy, for the price they are the best wheel we use
We also use abrasive technology vitrified wheels they are more expensive
When you work out how many tools you get out per wheel against cost of wheel you are just ahead so all is good

we are very happy with the construction of them, after inspection the wheels look perfect in the overall construction of the body and abrasive, of the highest quality I have seen, the 27mm hole size is a perfect fit to our machine spindle, the wheels run extremely true without any vibration or runout. We tested the grinding of the cbn with a light grind on a hss cutter and it performed excellently so far

Thanks you Alan, I wish you same your 1V1 diamond wheels are still amazing !
We have made about 50 or 75 custom dovetail tools and form tools and only had to dress them once
These are tools we recently made with your wheels
