Regarding Excel, we visited them to ask them to make acceptance letter for our machine and we found out that there are still two errors are often happen. They are ;
1. Camera Data Error (about 8-10 times per shift)
2. Divert transfer error (conveyor NG always can not transfer NG wheel to NG station)
Also they need your recommend grease type and viscosity of grease for the attached photo. it is not mentioned on manual book.
After the above problem are solved, they will sign the acceptance letter and they will pay the balance 10%.
