The Basic Principle Of Lens Grinding Equipment

Lens grinding equipment Purpose:

(1) to remove the grinding of the damaged layer to achieve the required appearance limits

(2) Refined surface shape, Lens Grinding Equipment to achieve the radius of the curvature of the radius R value, to meet the surface number of NR requirements and the aperture of the curvature of the local tolerance (Yasi) requirements.

Lens grinding equipment

Fundamental:

Through the mechanical movement, through the grinding plate, Lens Grinding Equipment grinding agent and the chemical between the glass, so as to achieve the purpose of precision polishing

The main control point of the lens grinding equipment

1. appearance with or without fixed, scar, sand, broken, frog skin, corrosion

2. Surface accuracy of the Asi, vertical, face number is within the standard

3. Whether the amount of grinding is within the standard

(Elliptical, saddle-shaped, cylindrical), Lens Grinding Equipment local irregular aperture (middle, high, low, vertical)

△ in the high ---- when the lens and the original device when the contact is exactly the same, small and medium aperture is too thick, pull the edge of the central convex concave, pull side 1/2, there will be oval

△ low ---- when the lens and the original device contact, fully consistent, the central aperture gap is too narrow, too close, pull the edge of the central convex outward, then 1/2 will appear when the oval

△ corrosion - commonly known as corrosion, is the optical lens surface and the outside air of water or other substances to produce chemical reactions caused by the block, point, mist phenomenon.

Lens grinding equipment Shockproof base, Lens Grinding Equipment designed to solve the existing lens grinding equipment, shockproof base installation process and easy to interfere with other parts, and its positioning pin connected to the base after the easy to shake, reducing the lack of shock effect. The utility model comprises a rectangular base body, and the base body is provided with a plurality of positioning holes, the positioning hole is a countersunk through hole, and one corner position of the rectangular base body is inclined trimming structure. Positioning hole for the countersunk through hole, rather than through the hole, increasing the positioning pin and positioning hole contact area, positioning pin connected to the positioning hole is not easy to shake, reliable positioning, shock effect. Rectangular base of the body of a corner position for the tilt of the trimming structure, the installation of the base of the body when it is not easy to interfere with other parts, easy to install.

Lens grinding method:

------- 1, put the lens in the grinding pad, the lens has an optical film and to be grinding surface.

The fluid guide tube covers the lens, and the fluid guide tube has a fluid inlet end.

------- 3, tangential direction, move, grind the pad to grind the surface to be polished.

Lens grinding method, first, the lens placed in the grinding pad, the lens has an optical film and to be grinding surface. Next, Lens Grinding Equipment the lens is covered with a fluid guide tube having a fluid inlet end and a fluid outlet end. The fluid outlet end is located above the grinding pad and is incorporated into the lens. Then, a fluid is continuously passed from the fluid inlet end into the fluid guide tube, and the fluid flows out of the fluid outlet end. The fluid can be uniformly applied to the surface of the optical film along the normal direction of the surface of the optical film. Then, the polishing pad is moved along the tangential direction of the surface of the polishing pad to grind the surface to be polished.
