Abstract
The invention relates to a processing method of a lens for a UV (Ultraviolet) camera lens. The processing method comprises the following steps that: (1) the positive pressure is controlled at 50kg and the rotational speed is 10rpm, and the coarse sand and fine sand shaping of the cut blank lens are carried out; (2) the blank lens is polished after being shaped, and the polished lens is cleaned by ultrasonic pure water; and (3) the cleaned lens is dried by a dryer, then enters an oven to be dried, and enters a 100-grade cleanroom for detection of various technical indicators to obtain the product. Compared with the prior art, the processing precision of the product processed by the invention is greatly improved.
Description
Technical field
The present invention relates to a kind of processing method of eyeglass, especially relate to the processing method that a kind of UV camera lens is used eyeglass.
Background technology
Along with the progress of science and technology, ultraprecise processing instrument is also being constantly brought forth new ideas.Although there have been precision and automated machine equipment in factory, still need corresponding processing instrument and process technology correctly, high-precision product manufacturing just can be finished.
Sphere and aspheric surface optical accessory are a kind of very important optical elements, and aspheric surface optical accessory is commonly used paraboloidal mirror, hyperbolic mirror, ellipsoidal mirror etc.Aspheric surface optical accessory can obtain the unrivaled good image quality of spherical optics part, but difficulty is also larger in processing.Generally, the processing method of ultraprecise processing can be divided into d-axis processing and inclined shaft processing, and d-axis processing refers to that the main shaft of cutter is vertical with the workpiece water plane, and inclined shaft processing refers to that the main shaft of cutter favours the workpiece water plane.Yet the mould precision that traditional processing method processes is not high, and working (machining) efficiency is lower, because process technology limit can only be processed miniature workpiece, and processing rigidity is also inadequate.Shi Naide has had to surpass the history in 100 years as one of three well-known macro lens manufacturing companies of Germany till now, and the said firm has also adhered to the German consistent style to the requirement of product quality.For the camera lens of φ 82*2.0, its aperture requires N=2, local error Δ N≤0.2, and surface smoothness 20-10, wherein the control for local error is particularly difficult.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of precision of processing to obtain the greatly processing method of the UV camera lens usefulness eyeglass of raising for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of UV camera lens processing method of eyeglass may further comprise the steps:
(1) the control malleation is that 50kg, rotating speed are 10rpm, and the blank eyeglass that cutting is obtained carries out coarse sand and fine sand shaping;
(2) again through polishing, the eyeglass after the polishing cleans through ultrasonic pure water the blank eyeglass after shaping;
(3) eyeglass after cleaning is finished advances oven for drying after drier dries, enter hundred grades clean room detection technique index, is product.
The THICKNESS CONTROL of the blank eyeglass described in the step (1) has the surplus of 0.5mm.
Need when the coarse sand in the step (1) and fine sand shaping the blank eyeglass is carried out turn-over processing, correcting process is carried out in 3 of every processing one time.
The blank eyeglass of polishing need carry out turn-over processing in the step (2).
Compared with prior art, the local error Δ N of the eyeglass that manufacturing of the present invention obtains≤0.2, surface smoothness can reach 10-20, and the precision of processing has obtained greatly improving.
The specific embodiment
The present invention is described in detail below in conjunction with specific embodiment.
Embodiment
A kind of UV camera lens processing method of eyeglass, may further comprise the steps: at first pass through the control of blank lens thickness, stay the surplus of 0.5mm, when grinding, pass through the technique of coarse sand fine sand, coarse sand technique uses light pressure (malleation 50KG), the slow-speed of revolution (10 rev/mins) first the blank eyeglass that has cut to be carried out shaping in earlier stage, subsequently intensified pressure and rotating speed.Simultaneously must guarantee that per one grinding technics all carries out turn-over man-hour adding, and per 3 dishes are revised once according to the rules, timely card are controlled.In polishing process, guarantee the flow process of processing in strict accordance with from large stretch of technological requirement of doing toward small pieces, process at every turn and carry out turn-over when more than half, guarantee that with this product can reach requirement.The follow-up ultrasonic pure water that carries out in thousand grades of clean rooms cleans, and after drier dries, advances oven for drying again, the clean room that enters hundred grades carries out the detection of various technical indicators, packed by vacuum packager in hundred grades of clean rooms at last, outbound namely obtains final product.
Claims (4)
1. the processing method of a UV camera lens usefulness eyeglass is characterized in that, the method may further comprise the steps:
(1) the control malleation is that 50kg, rotating speed are 10rpm, and the blank eyeglass that cutting is obtained carries out coarse sand and fine sand shaping;
(2) again through polishing, the eyeglass after the polishing cleans through ultrasonic pure water the blank eyeglass after shaping;
(3) eyeglass after cleaning is finished advances oven for drying after drier dries, enter hundred grades clean room detection technique index, is product.
2. a kind of UV camera lens according to claim 1 is characterized in that with the processing method of eyeglass, and the THICKNESS CONTROL of the blank eyeglass described in the step (1) has the surplus of 0.5mm.
3. a kind of UV camera lens according to claim 1 is characterized in that with the processing method of eyeglass, needs when the coarse sand in the step (1) and fine sand shaping the blank eyeglass is carried out turn-over processing, and correcting process is carried out in 3 of every processing one time.
4. a kind of UV camera lens according to claim 1 is characterized in that with the processing method of eyeglass, and the blank eyeglass of polishing need carry out turn-over processing in the step (2).
