2.5 The procedure to set up and prepare the camshaft for machining is described in accordance with grinding machine instructions. 2.6 The procedure to build up a camshaft lobe with hardfacing material is described in accordance with welding manufacturer instructions.
Keep in mind the tip of the lobe cannot exceed the height of the bearing journal on cams that slide through the block or head. So even when grinding blank billets to performance, the base circle quite often is smaller than stock. On cradle type bearing caps we still need to be cautious of too much lift and stock base circle for clearance reasons.

With the crankshaft straight, and the welded journal or thrust roughed in, it is now ready for the finish crankshaft grinding process. Although welding is most often used to repair damaged crankshafts, this process is also used to increase the stroke on performance crankshafts.
A crankshaft contains two or more centrally-located coaxial cylindrical ("main") journals and one or more offset cylindrical crankpin ("rod") journals. The two-plane V8 crankshaft pictured in Figure 1 has five main journals and four rod journals, each spaced 90° from its neigbors.
Like camshaft grinding, this modeling capability won't completely eliminate test grinding routines, but it does offer the chance to drastically reduce the number of test grinds and develop an optimized lobe grinding process in a more scientific way.
One of the most common machining operations performed on crankshafts is grinding. By grinding the rod and main journals, the bearing surface of the crankshaft can be repaired to provide a great foundation for a rebuilt engine.
Since the camshaft is supported on workrests, with the journals as a reference during camlobe grinding, it is important that the journals be ground properly because any imperfections will be translated to the camlobes during lobe grinding.

Following these precise machining procedures, our cranks undergo a second high pressure wash cycle to guarantee the removal of any debris that may have adhered or become dislodged during the grinding process. Absolute cleanliness is necessary for the next step of crankshaft remanufacturing, which is micro-polishing and or balancing if needed.

More Effective Camshaft Machining A leading manufacturer of high-performance valve train components installed a twin spindle/twin-turret lathe to bring camshaft machining work in-house. Here, the company explains how it has become more effective using its multifunction lathe to produce small batches of custom racing camshafts.
COMP Cams Engine Break-In Additive (part #159) ensures that the camshaft will have the lubricants that it needs to seat the camshaft journals and lobe/lifter surfaces. This lubricant is poured into the engine crankcase after the camshaft and lifters have been coated with the initial break-in lubricant (molybdenum disulphide) supplied with the camshaft.
