加工工艺Processing Technology
|
①无退火工序，透镜应力弱，防爆性能弱，易碎
No annealing step ,lens stress weak , explosion-proof performance is weak , fragile
|
①经过保温带工艺退火，透镜应力强，防爆性能好，不易摔碎
After annealing process , the lens would be strong,good explosion-proof performance, and not fragile
|
|
②工序，模压-粗磨-倒边-抛光，所有工序均为一出多，产品精度低，一致性差
Process： molding - roughing - bevelling - polished , all the processes are more than one , precision products is low, poor consistency
|
②工序，原材料抛光-模压-退火-敲边-粗磨-倒边-精磨-抛光-超声波清洗，所有工序均为一出一，保证产品精度以及一致性
Process： polishing materials - molded - annealing - Knock side - roughing - bevelling - grinding - polishing - ultrasonic cleaning , all the processes ensure product accuracy and consistency
|
|
②普通模具材料，模压成型透镜表面精度低
Common mold material lens is of low surface accuracy
|
③透镜模具采用日本进口特殊模具材料，模压成型的透镜表面精密度
高Japan imported special lens mold material ensure lens high surface accuracy
