Optics of PG of treatment of tall exact pattern is abrade technology

Grinder of curve of optics of brief introduction of grinder of PG optical curve renown PG(Profile Grinder) , it is the machining craft of a kind of tall nicety. Cooperate to machine with plotter, plotter depict gives the graph that requires treatment to be on film, film is stuck on umbriferous act corrective, the person that machine shapes what go up according to film will undertake processing. Optics is umbriferous and abrade those who fit tall hardness stuff shape abrade, for example material is wolfram steel character or the workpiece of hard alloy, now and then also process work of a few high-speed steel. Die of common treatment connector uses blade and drift, terminal, accurate hemistich Cheng punch, lower mould is entered piece mix makings board is entered child the workpiece that waits for and so on. Famouser optical and umbriferous muller comes from Japan to be produced formerly (group of AMADA nature field) , top rotate speed can achieve its main shaft 30000 turn, fluctuation journey most greatly 110mm, fluctuation journey rate is top it is 400 times / Mm, the precision of treatment is in 0.

002mm with , the unilateral of the smallest size of its machine stage is 0.

0001mm, the horn of R of the smallest of treatment is R0.

03mm, r horn is R0 outside.

02mm, the smallest part can achieve treatment abnormity punch 0.

06mm, the groove ratio of pit-depth to pit-diameter that its machine is in 2:1Or so, ra can amount to exterior surface roughness 0.

025 micron. Home's advanced PG optics is umbriferous and abrade the machine tool is (group of AMADA nature field) install an entrance formerly from Japan, and need examines and approve ability to import China through Japanese government. CNC Milling
