It is broken suddenly when your glasses are working normally,it becomes a disastar.

The rollers are turned to green when working after 2-3 years.

And other problems are continued...

Do you ever concern the most important factors which will lead to more problems?Maybe most of users do not care,just have glass products come out and we need to produce fastly and increase the production capacity urgently...

So let us make it clear,Roughness,T.I.R.,and diameter tolerance is the key factors which will influence your lifetime of fused silica roller.

Roughness is the first one factor,glasses will move over the rollers and it will generate friction on the roller,so good roughness will improve the quality of tempered glasses and reduce the dots on glasses,but what is the best value of roughness will be benefit to glasses?

T.I.R. is the shortage name of tolerance in rotation,when rollers are normal working,it will have tolerance in running,if it is bigger TIR,glass surface will have scraches or white lines or others.but what is the best value of T.I.R.?

Diameter tolerance is the judgement of roller if round or not,when the roller diameter tolerance is bad,the glasses will be unflatness,and it will generate optical distortion.It is not easy to find but many suppliers of glasses feel puzzled why our glasses are rejected goods which is completed and tempered partical is good?and also which is the best value of diameter tolerance? 

Freedom Ceramics will have three grades of fused silica rollers as per customers different tempered glass requests.
