Chrome steel balls are rolling, spherical elements that are used in check and ball valves, bearings, and other mechanical devices that provide rotary or linear motion. They are usually made from alloy steel, carbon steel or stainless steel. Metal balls are characterized by the Outer Diameter, Permissible Deviation, Surface Roughness and Tolerance. The Outer Diameter (OD) is the overall width or average diameter of the ball.
Stainless steel ball is one of the key components of bearings, which does not decouple and crack at high temperature, and its service life can be very long under normal working conditions.
Applications:
cosmetics, automobile transmission parts, bearings, sliding rails, rotating parts of furniture and electrical appliances, medical treatment, grinding, counterweights, etc.
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.
