1 back side of glass plate is by glue sticking on aluminum trays.
Layer of polyurethane is by glue sticking in 1 front of glass plate.
The manufacturing process of the utility model polished die is as follows:
Diameter 260-270 millimeters of 19-20 millimeters of thickness of plate glass is selected, 8 millimeters of diameter of Glass drill head is selected,
It is uniformly drilled with first through hole among glass plate, usually beats 12-14 hole, has beaten after first through hole to first through hole progress
Chamfering is then modified with face type and the depth of parallelism of the plane annular grinder to glass plate, using dial gauge to glass plate after finishing
It measures, guarantees that the overall flatness of glass plate within 0.001 millimeter, the depth of parallelism guarantees to use ab within 0.005 millimeter
Glue pastes the aluminum trays for being provided with the second through-hole, glass plate and aluminum trays coaxial arrangement, and glass plate at the glass plate back side
First through hole and aluminum trays the second through-hole to flatness is checked again for after just, gluing, if flatness does not change
Continue next step, flatness then continues to carry out glass plate ring mill finishing if there is a change, reaches overall flatness
To within 0.001 millimeter, glue is obtained in glass plate front bonding polyurethane layer with hundred later, and throw correction with plane contact block or ring
Disk flattens, and lifts down after 24 hours, polyurethane cutterhead corresponding at punching or electric iron are removed, hole is exposed, it is completed
Water is added to correct polished die 10-15 minutes with diamond pellet disk afterwards, finally, polished die is cleaned up.
Process using the polished die polish parts in the utility model is as follows:

Collector nozzle is filtered with silk stocking, to guarantee that polishing fluid cleaning need to will clean the non-dust cloth and silk stocking of filtering after polishing is primary
And replacement.
2, part size is checked before polishing, face type includes part curvature radius, surface roughness, and the depth of parallelism reaches requirement
Afterwards, part is cleaned, guarantees that piece surface does not have glass powder residual, part is lain on polishing machine, and is compacted with hand, with
Guarantee that part does not shake, dipped after polishing fluid is added to piece surface with writing brush, polished die that cleaning trims is placed on needs
On the piece surface of polishing, polished die 5-6 times corrected is pushed, with the stylus polished die on polishing machine, guarantees polished die position
It sets constant, burnishing parameters is adjusted according to the parameter that needs of optical element, the speed of mainshaft, balance staff revolving speed, amplitude of oscillation size, stylus is high
Degree, insurance support, polishing time, pressure size, pressure switch, pump switch start to polish, machine starts after confirmation mixes up
Operating 2-3 minutes, confirms errorless rear beginning press polish, increases stylus to the pressure of polished die by increasing counterweight on stylus
Power needs the water level for checking peristaltic pump in polishing process, guarantees that peristaltic pump water outlet is normal, avoids the occurrence of anhydrous dry throwing situation.Polishing
After 1.5 hours to 2 hours, part surface type and size are checked, when size is greater than 0.02 millimeter under part polishing, adjustment polishing in time
Parameters revision, to part polishing after, Cleaning of Parts is clean, and dry the water of piece surface, the finish of disk zero-detection part
With face type, protective paint lower wall is coated after reaching requirement.
It applies specific case in this specification to be expounded the principles of the present invention and embodiment, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model；Meanwhile for the general of this field
Technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up institute
It states, the content of the present specification should not be construed as a limitation of the present invention.
