Application of Bearing steel steel ball

Wuxi jinniu bearing steel ball could satisfy the current several markets the main industries: 

bearings, hardware, tooling guide sleeves, ball bearing slides, grinding materials, micro sprayer, polishing, decoration, toys, military industry, equipment meters,   automotives, motorcycles, bicycles, home appliances, chemical machinery, textile machinery, food machinery and mining machinery, etc.

 

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.

Quality Assurance

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.
