Problems solved by technology

The first process technology method is to re-grind the large and small surfaces of the input window, and then polish them until they are qualified; the disadvantage is that the removal of large and small surfaces is large, and generally it can only be repaired once. If it is not qualified after the repair, it is easy to The size is smaller than the requirement and becomes a waste product
The second process technology method is to re-polish the large and small surfaces of the input window once or more times until it is qualified; the disadvantage

Example Embodiment

[0033] Example 1

[0034] A method for polishing a glass input window element. The two surfaces of the glass input window element are respectively subjected to preliminary polishing and final polishing, including the following steps:

[0035] The small surface of the input window processed by the production line is made of high borosilicate glass with a diameter of ￠20mm. The aperture measured by a flat crystal is -13. It is observed with a 4X~10X magnifying glass under a black background light. Surface defects are IV Grade, and the depth of scratches and pitting is greater. Therefore, it is determined that the anti-halation glass input window must be repaired in two steps: preliminary polishing and finishing and final polishing and finishing.

[0036] In the preliminary polishing and finishing, manual polishing and finishing are used. The rotating speed of the polishing disc is 30 rpm; the pressure application part is on the outside of the glass, and the pressure is less than 0.25...

Example Embodiment

[0040] Example 2

[0041] The small surface of the quartz glass input window processed by the production line, the material is quartz glass, the diameter is ￠20mm, the aperture number N=-3 is measured with a flat crystal, and the surface is observed with a 4X~10X magnifying glass under a black background light. The disease is grade II, and the depth of scratches and pitting is very shallow. Therefore, it is determined that the anti-halation glass input window only needs to be repaired by the final polishing and finishing process.

[0042] In the final polishing and finishing, cerium oxide polishing powder is selected, the particle size range of which is 1.5-3 microns, and it is disposable; the ratio of cerium oxide to distilled water in the polishing liquid is 1:5 (mass ratio). The rotating speed of the polishing disc is 1300 rpm, the pressure position is on the outside of the glass, and the pressure is less than 0.25 bar; the pH value of the polishing liquid = 5.5; the effective ...

Abstract

The invention discloses a polishing method for a glass input window element and a clamp and belongs to the field of glass machining. According to the polishing method, initial polishing and final polishing are conducted on the two surfaces of the glass input window element. The polishing method includes the following steps that initial polishing is conducted, wherein the glass input window element to be polished is pressed on a polishing disc to be subjected to initial polishing till the number of apertures of the surface of the element ranges from 1 to 5; and final polishing is conducted, wherein the element obtained after initial polishing is pressed on the polishing disc to be subjected to final polishing till the defect of the surface of the element reaches the zero level standard. The polishing method has the beneficial effect of being low in rejection rate.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a polishing method and fixture for a glass input window element. Background technique [0002] Anti-halation glass input windows are used as light and image input windows for image intensifier tubes and lenses. With the emergence of high-quality image intensifier tubes and high-definition lenses, higher requirements are placed on the input window on the package. The anti-halation glass input window not only has the function of anti-halation and anti-glare, but also is an important channel for detection signal transmission, which requires good light transmittance, minimum image fluctuation and maximum image and signal resolution. To ensure accurate signal transmission. For this reason, the surface defects of the input window are required to meet the zero-level standard, that is, there are no surface defects such as scratches, pitting and broken edges visible to the naked eye unde...
