Grinding (Surface, Cylindrical, Tool & Cutter)

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, fields a question from a shop truing its diamond wheels offline, then remounting them onto the non-tapered spindle without using an adapter. The shop wondered whether its tight wheel tolerances negate the need for an adapter in the 31st episode of the video series.

I use resin- and metal-bond diamond wheels and used to manually stick them. Now our machine does it automatically and I don't have the "feel" to determine if the wheel is being stuck hard enough. Is there a way to know how fast I should stick?

Estimating burn depth is tricky. It depends on the thermal conductivity and specific heat capacity of the workpiece material, the maximum surface temperature reached and, most importantly, the time the wheel is in the grinding zone.
