Apr 23, 2018· Comp's History With Camshaft Grinding. In the mid-1990s, cam grinding was a comparatively simplistic process. Back then, Comp used a single-point diamond dress and conventional wheel to grind their camshafts. As effective as these were for the time, the procedure inevitably left an undesirable, gritty texture on the camshaft.

Camshaft cast to material patterns (done at foundry) Specifications determined by 'spec' sheet. Camshaft is 'faced'. Camshaft is then 'centred'. Camshaft is placed into CNC Lathe for rough turning. All pins and any tapping are then completed. Heat treatment is finalised. Restraightening of camshaft is completed. Grinding of journals is finalised.

Things to Know About Cam Grinding | AutoBeat

Camshafts control the opening, closing, lift and duration of valves. This means precision is essential to engine power, pick-up and fuel economy. Wear on your camshaft will cause excessive valve noises, engine roughness when idling, a lack of power and erratic operation.

Jan 01, 1983· (4) The grinding wheel has limited life due to accuracy dependence on size. (5) The set-up time for a new profile is very long. (6) The metal removal rate varies by a factor of 500: 1 round a typical profile due to the geometry of the wheel-to-work interface. The direct grinding of camshafts using a CNC machine eliminates all of these problems.

CRANKSHAFT grinding & Indexing. When a crankshaft is turned to an undersize, it can and does change the stroke and degrees apart of each rod journal. To index a crank, first the machinist has to know where the stroke and degrees (swing) are.

» Centerless grinding of cam and crankshafts

After cleaning the cam and journal surfaces, inspect them for any signs of scoring, pitting, or other damage. When you remove or insert a camshaft through the end of the camshaft recess, rotate it slightly. Rotating the camshaft allows it to enter easily and reduces the possibility of damage to the cam lobes and bearings.
