Know-How Notes: How A Camshaft Is Made - NAPA Know How Blog

Oct 26, 2016 . For custom grinds, a billet steel slug is used. There cams cost more because there is a lot more work involved, yet Comp Cams can produce custom grinds in just a few days. With a billet cam, every aspect of the cam has to be machined; there are no separations for the lobes, distributor drive, or journals.

Camshaft - Wikipedia

Billet Steel: When a high quality camshaft or low volume production is required, engine builders and camshaft manufacturers choose steel billet. This is a much more time consuming process, and is generally more expensive than other methods. However, the finished product is far superior. CNC lathes, CNC milling.

Crankshaft / Camshaft Grinding - HM GEM Engines

Crankshaft grinding/polishing and final inspection. The grinding process involves grinding a crankshaft with maximum measurements of 4,000mm in length and a 300mm stroke to the next available undersize. All journal machining is carried out according to the manufacturer's requirements and the fillet radii are dressed.

Camshaft Heat Treatment Explained - CPG Nation

May 2, 2017 . Copper masking on all but the cam lobes and journals keeps the rest of the core from being heat treated, which would result in a brittle cam. During the carburizing process, the cams are heated in a furnace in the presence of carbon dioxide. Once heated, the atoms of carbon find their way into the spaces.

Dec 1, 2007 . Lofting is a method of increasing lift where the lifter momentarily loses some contact with the nose of the cam lobe. "We have yet to find an application in which you wouldn't be better off with the increased lift designed right into the cam or rocker arm instead to allow controlled valvetrain operation," Billy.

Camshaft Bearings - King Engine Bearings

When speaking about engine bearings, most commonly, we focus on main and connecting rod bearings and the roles they play in crankshaft operation. Camshaft bearings are less loaded and generally have fewer problems. Therefore, innovative bearing materials and new designs are mostly focused on crankshaft.
