Deflashing: The flash line along the circumference is removed.
Heat Treatment: Chrome and bearing steel balls are thorough hardened.
Cleaning / Descaling: Basic surface cleaning is done.
Hard Grinding / Filing: An exacting process to achieve required sphericity and size of the steel ball.
Lapping: The final surface finish is acquired through this process.
Polishing / Burnishing: Surface lustre, work hardening, higher product life is achieved.
Passivation: Carryover iron and other contaminants are removed and a surface film prevents atmospheric and water corrosion on stainless steel balls.
Inspection: For surface finish, size and tolerance.
Rust preventive oil: Applied on chrome alloy steel balls to save from rusting and corrosion.
