Dear Khun Nattapon
SUS301-3/4H 0.8 x 6mm
Sorry! We can’t control the problem burr is no-burr on the F/G. because of thickness 0.8mm is very thick and width is small
but We are control spec.burr on the raw-material follow up to 0.08(Max) it’s okay
If you can change the specification for width 6mm. to 7 or 8 mm. (6mm.+loss(check your are machine)) We can support to you and the FG is no-burr
