Regrinding is always a part of the remanufacturing process. If the wear on a camshaft is minimal, the rebuilder may only have to regrind the cam to finish remanufacturing it. A remanufacturer will use a CNC grinder to grind down the lobes of the camshaft to ensure they provide the proper lift that is required for the engine.

grinding, as there is nothing available to quantify the finished cam to. This is a real problem for the grinder when checking the Jerk or 3rd derivative of the production cam, as Jerk can get very large in all the wrong places during grinding without the original data to compare. Jerk is basically the rate of change of the rate

Camshaft Heat Treatment Explained - CPGNation

Heat-treating a camshaft ensures the lobes will hold up under the demands of the valve train. Pushrods can apply as much as 2,000- to 6,000-lb loads between the lobe and roller wheels in a roller camshaft system, and as much as 10,000-lbs in Pro Stock engines. Most roller cams are made from either SAE 8620, SAE 5160, SAE 5150 steel or some ...
