Concave The grinding and processing principle and method of spherical surface

Basic principle of grinding process and processing method

Grinding is a precision machining process that is used when other metal cutting methods fail to meet the accuracy and finish requirements of the workpiece. Grinding is usually done by hand, adding abrasive between the grinding tool and the abrasive surface, and grinding a very thin metal layer from the surface of the part to achieve a high ...

Reflection at Spherical Surfaces: Spherical, Concave, …

2022-6-24 · Spherical mirrors are a type of curved mirror that is spherical. The reflecting surface of a spherical mirror is a part of a sphere. Thus, it is either curved inwards or curved outwards. The rays of light after reflection from the spherical surface meet a point and form an image at that point. For image formation, we need at least two rays of ...

SPHERICAL LENS SURFACE PROCESSING METHOD AND …

In a spherical lens surface processing method, a lens surface is ground to a spherical surface by forming a contact state in which a rotating cup-shaped grinding stone is placed in contact with the lens surface and a sphere center oscillation state in which the cup-shaped grinding stone oscillates along the lens surface centered on a sphere center.
