Name: metal bond diamond pallet for optical glass
Metal bond diamond finish pellets
Metal bond diamond pellets are used in the finish grinding process
for optical glasss.The main function of diamond pellets is to
remove the damaged layer and rough surface left by the milling
process, to ensure that the optical glass elements have a certain
surface size and machining margin. Metal bond diamond pellets are
made by mixing diamond powder, metal powder and filter, and then by
cold pressing or hot pressing sintered.
Resin bond diamond super finish pellets
Resin bond pellets are used ffor super finish grinding process of
optical glass elements, which remove the damaged layer (rough
surface) left over from the previous finish grinding process, and
further improve the shapes and sizes of optical elements,
smoothness and aperture value. Also,the appearance is similar to
the metal bond diamond pellet. Resin bond diamond pellets are made
by mixing diamond powder, resin powder and filler, and then by cold
pressing or hot pressing sintered.
Use cases of diamond pellet
1 General process: optical elements through finish grinding process
– super finish grinding process -polishing.
2 Non-general process: Choose rough and finish two or more kinds of
diamond finish pellets (columns) for two or more stages of finish
grinding, to do two processes of finish grinding and super finish
grinding, and directly to the polishing process.
3 Non-general process: Get rid of the finish grinding process of
diamond finish pellets (columns), and directly use two (or more)
kinds of diamond super finish pellets (columns) for two or more
stages of grinding, without polishing process, to achieve optical
elements from blank to finished product processing.
Practice has proved that 2 and 3 two methods can achieve the same
effect.
