The hard optical material polishing die combined structure is simple and convenient to manufacture, the materials are easily obtained, the durability is more than three times that of the classical polishing asphalt; the hard optical material polishing die combined structure can be widely applied to the polishing processing of a hard optical material; when in use, the classical polishing machine tool can be directly put into use without changing, so that the cost advantage is obvious.
Description
Technical field
The invention belongs to optics cold working field, relate to a kind of polished die for rigid optical material, be specifically related to a kind of rigid optical material finish mould composite construction and preparation method.
Background technology
Along with the development of precision optics technology and demand, the application of rigid optical material as monocrystalline silicon, spinelle, sapphire etc. is more and more extensive.It is the obstruction applied that the precision of rigid optical material finish processing, efficiency are difficult to take into account always.
Rigid optical material have two kinds of finishing methods, classic polishing processes and high-rate polishing method.Classic polishing processes adopts polished die metallic matrix applying polishing pitch and be made into, the polishing of low speed low pressure, has that surface figure accuracy is high, the feature of excellent surface quality; The shortcoming of this method is, aging and follow the string and cause needing frequently to reform after polishing pitch is easily heated, and the polished die polishing efficiency that polishing pitch makes is low.High-rate polishing method employing metal base surface posts the polished die that polyurethane polishing leather is made, high speed and high pressure polishing, be characterized in that polishing efficiency is high, surface quality is medium, but its shortcoming is polished die makes complex and expensive, and the surface figure accuracy obtained is difficult to the requirement meeting precision optics.
Summary of the invention
In order to avoid the deficiencies in the prior art part, the present invention proposes a kind of rigid optical material finish mould composite construction and preparation method.
A kind of rigid optical material finish mould composite construction, is characterized in that: comprise metallic matrix 1, asphalt elasticity layer 2 and some polyurethane polishing discs 3; The aspect of metallic matrix 1 is asphalt elasticity layer 2, asphalt elasticity layer 2 is provided with multiple polyurethane polishing disc 3; Described polyurethane polishing disc adopts circular piece.
Further preferred version, described a kind of rigid optical material finish mould composite construction, is characterized in that: described polyurethane polishing disc adopts circular concentric distribution mode to adhere on asphalt elasticity layer.
Further preferred version, described a kind of rigid optical material finish mould composite construction, is characterized in that: described polyurethane polishing disc adopts helix distribution mode to adhere on asphalt elasticity layer.
Further preferred version, described a kind of rigid optical material finish mould composite construction, is characterized in that: some polyurethane polishing disc entirety forms plane.
Further preferred version, described a kind of rigid optical material finish mould composite construction, is characterized in that: some polyurethane polishing disc entirety forms convex spherical.
Further preferred version, described a kind of rigid optical material finish mould composite construction, is characterized in that: some polyurethane polishing disc entirety forms concave spherical surface.
Further preferred version, described a kind of rigid optical material finish mould composite construction, is characterized in that: described asphalt elasticity layer thickness is 1-10mm.
Further preferred version, described a kind of rigid optical material finish mould composite construction, is characterized in that: described asphalt elasticity layer adopts the trade mark to be the polishing pitch of 64#-70#.
Make a method for described rigid optical material finish mould composite construction, it is characterized in that step is as follows:
Step 1: by multiple polyurethane disk, arrangement mode selectively posts on optical flat;
Step 2: apply polishing powder in the space between urethane film, is heated to 40 DEG C and keeps;
Step 3: pitch is placed on metallic matrix, then after heating of metal matrix to pitch is in melting state, by pitch even application in matrix surface, reach the thickness of needs at pitch thickness after, the one side being placed with polyurethane disk with the metallic matrix of asphalt elasticity layer and optical flat is fitted, take off optical flat after naturally cooling to room temperature, remove the pitch in polyurethane disk gap, complete polished die.
A kind of rigid optical material finish mould composite construction that the present invention proposes has had the efficient polishing ability of mobility that polishing pitch has and polyurethane concurrently, polishing time can be shortened 50%, under the prerequisite meeting surface figure accuracy, effectively can improve the polishing efficiency of rigid optical material.This rigid optical material finish mould composite construction is simple for production, and material easily obtains, and the more classic polishing pitch mould of durability improves more than 3 times, can be widely used in the polishing of rigid optical material.Do not need to carry out change to classic burnishing machine during use can use, there is cost advantage significantly.

Detailed description of the invention
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
Cut the polyurethane disk of some Φ 16mm bores, arrangement mode selectively posts on optical flat, and the arrangement mode of polyurethane disk can be circular concentric, also can be spiral yarn shaped, is circular concentric in the present embodiment.In the space of urethane film, coat polishing powder, with infrared lamp, its surface heating to 40 DEG C is kept stand-by.After heating of metal matrix to polishing pitch is in melting state, by polishing pitch even application in metal base surface, and reach the thickness of needs at asphalt thickness after, the metallic matrix with asphalt elasticity layer is pressed in optical flat and is placed with in the one side of polyurethane disk, then naturally cool.Generally asphalt elasticity layer thickness is required that, for 1-10mm, the present embodiment requires as 8mm asphalt elasticity layer thickness.Taken off from optical flat by the polished die of cool to room temperature, remove the outstanding pitch in polyurethane disk gap, ensure that pitch height is lower than polyurethane disk, namely polished die completes.
As shown in Figure 3, this rigid optical material finish mould composite construction is clamped on lathe by screwed hole, after adding polishing fluid, rigid optical material finish mould composite construction puts part 4 to be processed, part 4 to be processed is gluing with fixture 5, is connected with external agency by fixture 5.External agency applies pressure to fixture 5, and start lathe, rigid optical material finish mould composite construction is driven to do gyration, part 4 to be processed does reciprocally swinging and does gyration with rigid optical material finish mould composite construction because of frictional force, realizes adopting classic polishing mode to carry out polishing.
