Grinding Rubber....Help Practical Machinist
Sep 30, 2016· If you are into grinding rubber on a regular basis, I recommend building one. Here is the basic belt grinder, just think vertically, build it to fit your compound rest and have the contact wheel on center with the roll you are grinding. Be sure to use a reversible motor, variable speed. This one uses 2-1/2 inch wide Norton belts, 60 inches long.
