Minimise wear and prolong service life with our microfinishing technologies


The right microfinishing technologies are critical for minimizing wear and prolonging the service life of today's engine components.

Mirka’s microfinishing solutions are used in many engine and powertrain applications where demanding tolerances are required, such as; crank, cam, piston pins, piston rings, balance shafts, piston rods, and rotor shafts.

In the modern powertrain industry there are many challenges – we can meet them together to:

•Decrease emissions
•Obtain improved friction and tribological properties
•Optimise and save costs
•Increase flexibility
•Improve supply chain efficiency
