Dear Mr. Tea
As per this morning conversation on 2 points which you have identified. We will arrange Chaipichit San and Brother staff to visit and further understand your problem.
Dear Chaipichit
Seksun has commented 2 issues as follows
1. Tool change not in correct position due to the key way not seating correctly resulting in tool dropped.
2. Coolant has stopped but there is still slight air blow and causing chip to stuck on the pull stud ( Arbor)
Please coordinate with Nishigaki San and visit Mr. Tea together.
