Hey Adam! A dive into the finer points of using a speed control on the spindle would be cool. They can make a wheel behave harder or softer and save dressing and changing wheels some. Great for CPM steels. Also, a must-have for diamond wheels/carbide grinding IMO. They improve my productivity and wheel cost - can't live without them.

This is a wonderfully described process. I "stumbled" onto this process while grinding .060" thin D2 cutter blades. Didn't know it had a name! I use it on most things I do now. You don't spend time dressing your wheel with this process as the leading edge is breaking down and exposing fresh grains yet the trailing edge is remaining stable and consistent.

I was checking to see if anyone else made your point about dressing, otherwise I was going to. I actually find this technique (I, too, never knew it had a name) gives me a better finish on some machines, I assumed it was because the grains which did the finishing were well sorted (any rogue grains with their "heads above the parapet" having been knocked out) and would give a better finish than a fresh-dressed wheel would at the beginning of a finishing pass.
@Gottenhimfella

Furthermore it seems to bme that the leading edge of the wheel, because of the substantial depth of cut, is having any blunted grains torn out in short order, keeping the business end of the wheel free-cutting, because there are always plenty of sharp grains being "brought into play", like fresh players in rugby whent there is a high injury rate and a "deep bench".

I love you can set up the grinder on a fine cross feed and go do something else. It keeps the wheel sharp exposing new grains. I`ve worked in a job shop since the 80`s . I`m just about to retire.

Does the wheel breakdown of that leading edge actually create the longer ramp? Are you able to go longer between wheel dressings, since the part of the wheel that 'wipes' the part to final dimension is doing so little work?

Eventually the wheel will start to shed grains as they dull, exposing a new sharper corner of grains . Prolonging the interval between dresses is a key advantage of this

Very interesting technique! Thank you for sharing. Would you recommend this technique for thin stock with inner strees? I mean from knifemaking point of view we usually grind blades or titanium handles which are around 4 mm thick. After milling or grinding they tend to bend pretty much because of inner stresses... Do you think this technique will be better for flattening than regular wheel grinding?

The scale is along side the right/rear of the column( as you face the machine ) with the split rubber seal pointed rearward, and the reader head anchored to the motor housing.

Plunge and traverse grinding are two more common ways of removing material. Traversing is how most semi auto grinders remove, plunge meaning the wheel slowly moves down till final depth is hit and then moves over 90 percent of the wheel width and repeats until the part is ground. And yes, without coolant those options do tend to create more heat than peel grinding . The neat thing about this work is all the different ways to do the job
