A cam grind is then chosen that maximizes engine power out in the rpm range where it really needs it. A bigger cam might make more total power, but if the engine seldom revs high enough to take advantage of that extra power it's more cam than the engine really needs.

The grinding wheel is mounted on a rocking arm that pivots on the third. It too can be repositioned and locked over the cam locations. A follower attached the arm rests on the master cam. The moment arms provide the scale-down factor from master to generated cams. The inter-connected shafts need to be rotated at a relatively slow but steady rate.

Raw, un-ground camshafts have a case-hardened rim on each lobe that penetrates this working surface by 0.200in to 0.250in. When finish-ground, the case-hardened surfaces must achieve a minimum depth of 0.100in. If less, the lobe will be impaired and likely fail. But the camshaft grinder has around 0.150in to work with, so where's the problem?

The cam is connected by a 2-1 ratio sprocket or gears, so it only turns once to the crank's two turns (Two crank degrees equal one cam degree). When viewed from the front of the car, the crankshaft turns clockwise. The camshaft also turns clockwise if connected via sprockets and chain. It turns counterclockwise when connected by gears.

Organic (resin) bonded wheels will act softer due to the ways in which the bonds work. More heat in the grind zone will soften the wheel quicker, increasing the odds of early wheel wear. 7. Machine/Spindle Horsepower. The horsepower of the grinding machine can play a role in determining the grade of the bond or the hardness of the wheel.
