SteelBeads Micro are spherical cast steel grinding beads of tempered carbon steel. The finegrained microstructure of the grinding beads give them a long lifetime and high breakage resistance. The SteelBeads Micro are available in a diameter range of mm to mm.
Spherical Lapping. LAPMASTER WOLTERS Spherical LappingPolishing Machines have been developed to produce very accurate spherical surfaces on a variety of components and materials...Spherical tolerance accuracy to within 1 micron is obtained on scratchfree, mirror finish highquality surfaces (applies to both male devices).
Common Optical Defects in Lens Systems (Aberrations) Microscopes and other optical instruments are commonly plagued by lens errors that distort the image by a variety of mechanisms associated with defects (commonly referred to as aberrations) resulting from the spherical geometry of lens surfaces.

Ultraprecision machining using micro size diamond cutters can be used to create true 3D optics with relatively easy setup and fast turnaround. Micro milling and grinding technologies can be used for the production of plano, spherical, aspheric, conformal, and freeform optics.
Home / About Us / Technology / What is Spherical Lapping? 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.

The average rotational speed of abrasive wheel and/or workpiece is 1 to 15 surface m/min, with 6 to 14 m/min preferred; this is much slower compared to grinding speeds around 1800 to 3500 m/min. The pressure applied to the abrasive is very light, usually between to MPa (3 to 10 psi), but can be as high as MPa (299 psi).

Ball bearings are generally made of chromium or stainless steel, although they can also be made of ceramics or brass. To ensure smooth and efficient operation, the surface roughness of ball bearings must be accurately measured during the production process, especially after the balls have been ground.
