The materials controlled as necessary are treated in CNC machines (counters) within suitable tolerance values. If there are lubrication grooves in the bushing, these grooves are opened. The materials treated in suitable sizes are controlled after they are reached to necessary hardness value by subjecting them to cementation and interior-exterior surface grindings are performed. The bushings whose eligibility checks are performed are branded according to the brand and model numbers. They are packaged and put on the market after the protective lubrication is performed.
