Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore above-mentioned term cannot
It is interpreted as limitation of the present invention.
The present invention is described in detail with reference to the accompanying drawings and detailed description, embodiment cannot go to live in the household of one's in-laws on getting married one by one herein
It states, but therefore embodiments of the present invention are not defined in following implementation.
Referring to figs. 1 and 2, the polishing method of optical lens surface of the invention includes: that material is arranged in and adds by S1.
In working solution 1 added with suspension grinding material；S2. the working solution 1 is heated to preset temperature T and kept constant；S3. to the work
Make liquid 1 and applies the surface that ultrasonic activation polishes the material.
Specifically, in the present invention, before polishing to optical lens surface, need to set burnishing device, i.e.,
The deployed working solution 1 added with suspension grinding material in ultrasonic equipment 4 is needed, then places polished optical mirror slip 2
Into cleaning basket 3, cleaning basket 3 is put into working solution 1 later, the ultrasonic equipment 4 for setting parameter is opened, by working solution 1
It is heated to preset temperature T to keep constant, carries out ultrasonic activation later, by the suspension grinding material in working solution 1 to optical mirror slip
Surface grinding-polishing.Polishing method is simple and convenient, while can effectively solve the problem that infrared optical material eyeglass through surface mirror finish
Afterwards, due to circular flow pollution, the resting period it is too long caused by mouldy, the bad problem of caused surface smoothness.In addition,
It is small for the macroforce of optical mirror slip due to the mode using ultrasonic activation, optical lens surface face type will not be caused
Variation.
The suspension grinding material added in working solution 1 of the invention should be high rigidity, dystectic substance.Specifically, this hair
The hardness of suspension grinding material in bright should be greater than the hardness of material (polished eyeglass), and the fusing point of suspension grinding material should be greater than material
The fusing point of (polished eyeglass).So set, protect suspension grinding material can under conditions of preset temperature T and ultrasonic activation
Working performance is demonstrate,proved, suspension grinding material can be effectively ensured for the polishing effect of optical surface.A kind of implementation according to the present invention
Mode, the suspension grinding material added in working solution 1 are aluminum oxide.It is of course also possible to other high rigidity, dystectic substance,
