Dec 13, 2018 In process grinding measurement. We have a rotary surface grinder that we would like to improve accuracy of finish thickness to - 0.0002 inches. The parts are Rc60 - Rc65 and we are finding that the wheel loading changes significantly between wheel dressings and downward force on the wheel chuck interface varies from 800 lbs on a freshly ...

Calculate Cost Steves Stump Grinding

Calculating the cost of grinding a stump is fairly easy. A little measuring and some simple calculating and your done. We charge 5.50 per inch. The way you figure the inches is you measure the diameter width of the stump at ground level. If the ground is humped up around the stump, extend the diameter to include grinding the hump to grade level.
