Description
Technical field
The present invention relates to optical mirror slip manufacture field, particularly a kind of processing technology of heat-sensitive material eyeglass.
Background technology
Traditional machining eyeglass technology adopts follow procedure: roughing is cut, and machining eyeglass is become certain shape, dimensional accuracy and surface roughness, plays shaping effect; Again via precision grinding process, the eyeglass that eyeglass is roughly ground out by its breakable layer to eliminating, the R value of fixing len; Then adopt edging operation, the external diameter of original eyeglass is ground to the external diameter of specifying; Afterwards by polishing process, will refine eyeglass polishing again, this procedure is mainly done better the outward appearance of eyeglass; Eventually pass wiping and cleaning finished product.
In this process of polishing, the large face of the polishing fluid that polishing process mainly adopts polishing powder to be made into eyeglass is ground, the performance of polishing fluid and have important impact to the working (machining) efficiency of polish parts and surface quality with the Proper Match of other process conditions.Special in current H-FK

53deng mirrors material, these materials due to soft and its temperature difference itself more than 3 ~ 5 DEG C after then can burst, there is a series of problem in therefore traditional processing technology, and yield rate is very low in process.Traditional polishing is that polyurethane is placed on mould, an eyeglass of polishing leans against on polyurethane, with the polishing of cerium oxide suspension, polyurethane is on nethermost mould, and what shower nozzle sprayed is cerium oxide suspension, the product Problems existing processed by the method: surface quality (scuffing, pit, cleannes, cerium oxide are piled up) is poor, product qualified rate is lower, waste resource, adds entreprise cost, brings serious waste to enterprise.
Therefore, need now to develop a kind of can be applicable to heat-sensitive material eyeglass high-effect high-quality and the processing technology of the high heat-sensitive material eyeglass of yield rate.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of can be applicable to heat-sensitive material eyeglass high-effect high-quality and the processing technology of the high heat-sensitive material eyeglass of yield rate.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is, the step of this heat-sensitive material machining eyeglass technique comprises processing in early stage, polishing, cleaning, edging and following process successively, and described polishing step is divided into rough polishing technique and finishing polish technique; The process of described rough polishing technique is for add polissoir by rough polishing solution, rough polishing pressure is not more than 0.2MPa, described rough polishing solution is the suspension of cerium oxide in water, the concentration of described rough polishing solution is 200g ~ 300g/250ml, adjust ph remains on 6 ~ 9, and the polishing time of described rough polishing technique is 5 ~ 10min; The precise polishing solution of described finishing polish technique is that the ZOX-N polishing fluid of the commercially available Worldwide, Inc of the U.S. of 130g ~ 170g adds cerium oxide 10g ~ 50g again and is dissolved in water, and the concentration of described precise polishing solution is 140g ~ 220g/10kg, and adjust ph remains on 6 ~ 9; Finishing polish pressure is not more than 0.05 ~ 0.1MPa; The polishing time of described finishing polish technique is 2 ~ 3min.
Adopt technique scheme, by second polishing technique, can realize carrying out polishing to heat-sensitive material eyeglass, require in rough polishing technical process that heat-sensitive material lens surface does not have serious scuffing, slight cerium oxide can be had to pile up, and eyeglass the control of diaphragm can than low 1 ~ 2 circle of drawing requirement; Wherein the effect of concentration to this rough polishing technique of rough polishing solution plays a part key, and in polishing process, the concentration of rough polishing solution determines polishing velocity, and the larger polishing velocity of concentration is higher; But for heat-sensitive material eyeglass, easily burst in process, therefore will control the speed of polishing, thus ensure the processing of heat-sensitive material eyeglass; Heat-sensitive material lens surface 20/10 is required in rough polishing technical process, aperture 2 encloses/and 0.3; Namely surface quite GB one-level to two and between, face type error 0.0005mm, local error 0.000075mm need detect with special equipment; The polishing time of rough polishing technique depends on the diameter of eyeglass; Adding a small amount of cerium oxide in wherein finishing polish technical process is time in order to shorten finishing polish technique, improve the efficiency of its finishing polish technique, mainly because the ZOX-N polishing fluid of commercially available Worldwide, Inc of the U.S. does not have stock removal rate, so need add a small amount of cerium oxide, the time of not so finishing polish technique can be very long; This processing technology is applicable to 80mm and above machining eyeglass.
The present invention improves further and is, this heat-sensitive material eyeglass is H-FK
