Why is laser fine machining of abrasive films so important for camshafts or crankshafts?

Microfinishing is the process of removing microscopic amorphous surface material left behind during the grinding of dimensionally finished parts, such as crankshafts, camshafts or pump shafts, to achieve a high-precision fit with mating parts.

Microfinishing produces the final functional surface texture required to reduce friction, improve performance and increase reliability of precision shafts. Microfinishing tolerances cannot be achieved by grinding.

鈥淚n today鈥檚 automotive engines, the surface textures of these functionally critical features on internal engine components are micro-machined to very fine tolerances, allowing the internal combustion engine to operate more efficiently and meet emissions, horsepower and fuel economy targets,鈥?said Mark Hendel, IMPCO鈥檚 Global Sales Director.

During the microfinishing process, the abrasive film is fed through a pair of opposing arms, each with a fixture shaped to fit the cylindrical bearing journal of the part. During the process, the arms close around the journal, holding the film on the rotating part for a specified time to achieve the desired surface texture.
