They are similar, but not the same.
There are differences in base materials, in weight, and in the hardness of the surfaces.

At this point in time i have no hands-on experience with MDF for this particular method of motorized sharpening (only for hand strops), but a member of British Blades passed on a warning to me that he received from an English company specializing in polishing equipment, that in the professional world home-made MDF Wheels are considered too dangerous to use.
It seems that they can come apart suddenly due to the centrifugal forces most benchgrinders can create.

Dustar Model 1 Arad 67 Commemorative combat knife from a collector.
The factory "edge" was very rough and also still had a burr so thick that i could lift the entire knife from the table by hooking it with my finger nail.
Edge angle was +/- 45 degrees inclusive which i left intact as the customer did not want wider bevels.
After grinding the apex flat on the Tormek Blackstone the edge was resharpened on a Paper Wheel with 15 micron diamond compound then deburred with a second Paper Wheel with 3 micron diamond compound, an the new edge can just treetop the hairs on the back of my hand.
Probably the most wear resistant D2 steel i have sharpened so far.

This vintage Al Mar Applegate Fairbairn dagger from a display collection had factory edges which were rather coarse, had a few flat spots, and a flattened point.
Since the "R" from Rex Applegate's signature was already quite close to the +/- 50 degrees inclusive factory edge i chose not to reprofile but instead just polish the existing bevels a bit with successively 15.0 micron, 3.0 micron, and 1.0 micron diamond compound on dedicated Paper Wheels.
Both new edges can shave the hair on the back of my hand on skin level.

Another PM2 in S110V.
The new edge was done on a Paper Wheel with 15 micron diamond compound, and then refined with 6.0 micron, 3.0 micron, and 1.0 micron diamond compound, all on dedicated Paper Wheels.
The apex is keen enough to whittle several curls in a row on one of my chest hairs while holding the hair at the root end only.

The owner of this Maxamet PM2 had given his knife a forced patina treatment, and besides coming out a bit uneven the acid had also completely eaten away the factory apex as well as the very tip of the blade.
To say that the knife was completely blunt would have been an understatement.
The request was to give the knife a new toothy edge with a lot of bite while making it as sharp as possible.

Before sharpening:











After sharpening
Flattened the acid damaged "apex" some more on a 3000 grit diamond plate so i could start with fresh steel, then made a new edge on a Rubber Wheel coated with +/- 230 grit diamond powder & wax, then deburred on a Paper Wheel with 1.0 micron diamond paste & oil.
The new edge is ever so slightly convex, the new apex fits almost exactly in the 30 degree inclusive slot of my Tormek WM200 Angle Master, plus it can whittle one of my chest hairs at about 5.5 centimeters from the point of holding. (i don't own a BESS tester)
The somewhat "fuzzy" shoulders of the new edge show how deep the acid has eaten away into the sides of the blade in some area's.

Those edges look gorgeous.

However, I wonder whether the blades get hot while you sharp them. An often used argument against belt grinders is that the blade will get hot and that this will affect the hardening of the blade.

And it's a very valid argument i can tell you.
That is also why my Wheels have a coating of cooling wax or oil on top of the abrasive so overheating will not happen.
Something i know for sure as i test every edge i sharpen this way afterwards by cutting several times into a testing block and measuring sharpness before & after testing.
