Check this page out. It is a company the regrinds cams. They explain what they do exactly about halfway down the page.



Here is most of it. . .

It is a well-known fact that regrind cams have one huge advantage over aftermarket grinds performed on new billets. It’s price. Regrind camshafts run anywhere between 50-70% less than new billet cams. That’s a given. But, do regrinds have any other advantages. The answer is yes. Regrinds are cut off factory cams that have factory set indexing. That’s obvious and what we want. But, new cams are sometimes not! Ever hear about the need to index aftermarket cams? This procedure is performed because the aftermarket company has incorrectly cut the cam lobe centers in relation to the gear.

What other benefits do regrinds on factory cams have over new billet cams? Well, again they are cut on factory billets! And, they have guaranteed factory hardness. Let’s sum up these points:

Regrinds are easily cut on factory lobe centers eliminating the need for indexing which the majority of shops do not perform. Indexing is a fairly difficult job and requires an expert mechanic most likely with machining skills. Some cams cannot be easily indexed.

Regrinds, being cut on stock cams, guarantee factory hardness.

Best of all, regrind camshafts run 50-70% cheaper than cams cut on new billets.

In all fairness, there can be disadvantages to regrinds. For one, regrinds are typically created by reducing the base circle of the camshaft. The heal area is usually reduced to create more lift. Thus, total lift is limited to the amount of material that can be sacrificed on the heal. If too much material is removed off of the cam heal, the lifters may forced to over extend in order to reach the cam. This can lead to premature wear of the lifter. For cams that use shimmed valve clearances, this is usually not a problem. Thus, regrind cams need to be correctly designed. There is no mistake about this.
