Piston rings are critical components of internal combustion engine pistons. Installed in the piston ring grooves, they come into direct contact with the cylinder walls, and their performance directly affects the engine’s sealing, lubrication, combustion efficiency, and service life. Ensuring the surface profile accuracy of the piston rings directly impacts the fit between the rings and the cylinder, thereby preventing air leaks and abnormal wear.
