The Manufacturing process for balls, stainless steel balls ...
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.
Process parameter optimization and anisotropy sensitivity ...
where h(x) is the value of the roughness profile and L is the cutoff length.. Five different positions with the same cutoff length (L = 20 mm) were measured on each grinding track to increase the reliability of the experimental results.The average value of R a is taken as the final test result. MRR and B w are expressed as weight loss per unit time of workpiece and abrasive belt, respectively.

All About Aspheric Lenses | Edmund Optics
Spherical Aberration Correction. The most notable benefit of aspheric lenses is their ability to correct for spherical aberration, an optical effect which causes incident light rays to focus at different points when forming an image, creating a blur.Spherical aberration is commonly seen in spherical lenses, such as plano-convex or double-convex lens shapes, but aspheric lenses focus light to a ...
What is Spherical Lapping and Polishing?
What is Spherical Lapping? The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.
