Bearing steel steel ball Production Flow
Heading: A coil of wire is cut to the required length and each piece compressed and shaped into balls using a pressing machine.
Flashing: The surface of the balls is ground to remove the bands generated in the heading process.
Heat Treatment: After the bands have been removed, the balls are quenched adn tempered to give them sufficient strength and durability.
Grinding: In addition to removing parts decarburized in the heat treatment, this process adjusts dimensional precision and finishes the balls to the stipulated dimensional difference.
First Lapping: The dimensional precision of the balls is further improved and they are finished to the specified dimensional difference.
Second Lapping: In addition to increasing the balls' dimensional precision to grade level, this process gives the surface of the balls a smooth, glass like finish.
Finishing: Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.
Inspection: All products pass through least two 100% inspection stages, using proprietary, automated inspection processes.
Packaging: Balls are treated with anti-corrosive oil and then packed in paperboard boxes.
After precision washing, oiling & before packing sample balls from the batch are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer. Our sophisticated laboratory is equipped with high precision, worldwide respected machines and equipment and is managed by properly trained and qualified personnel.
