Why laser fine processing of abrasive film is so important for camshafts or crankshafts?

Coptics Laser

Micro finishing is the process of removing the microscopic amorphous surface material left during the grinding process of dimensional finishing parts (such as crankshafts, camshafts or pump shafts) to achieve high-precision matching with mating parts.

Micro-finishing can generate the final functional surface texture required to reduce friction, improve performance, and increase the reliability of precision shafts. To prevent grinding cannot reach micro-finishing tolerances.


In today's automotive engines, the surface textures of these functional key features on the internal components of the engine are micro-machined with very fine tolerances, allowing the internal combustion engine to operate more efficiently and meet emission, horsepower, and fuel economy goals.


In the micro-finishing process, the abrasive film is fed through a pair of opposed arms, and the shape of each fixing tool is adapted to the cylindrical bearing journal of the part. During this process, the arm is closed around the journal and the film is held on the rotating part for a specified time to obtain the desired surface texture.
