Customized G10-G1000 1.0mm-120mm Carbon Steel Ball for Bicycle Parts

Product Production

Heading: 

  In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.

Deflashing:

  The flash line, a ridge left by the forming dies, is removed as balls roll between heavy,cast iron plates.

Soft Grinding:

  Similar to deflashing, except that a grinding stone is used to improve precision.

Heat-treating: 

  Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.

Descaling: 

  This step removes the residues and by-products from the heat-treating process.

Hard Grinding: 

  Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as closeas ±.0001".

Lapping: 

  Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade10 - 48. 

Finishing: 

  Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.
 

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.

Our steel balls is used in many industrials, such as precision bearings, automotive components (brakes, steering, line shaft), bicycle, agitators, appliances, sliders, quick couplings, machine tool, lock mechanisms, conveyor belts, skates, pens, pumps, castors, measurement instruments, valves, ect,.
