About This Part
At Ø50 by 1.5 mm, this cover is a flatness problem wearing a disc costume. Thin discs warp when you look at them, so the plate is milled with light symmetric passes and held flat through finishing. The face must come through clean: no burrs, scratches, dents, or missing material, per the drawing appearance note.
Three and a half M2 positions carry the closure threads, with C0.3 default chamfers and GB/T 1804 f class for unmarked dimensions. The finish is 120 grit bead blast plus black anodize, which evens out on thin parts only if the blast media and timing are consistent, so the process runs automatic blasting with fixed parameters.
Inspection is dimension, appearance, and coating check, with the appearance and finish uniformity as the practical acceptance surface.

Common Questions
How do you keep a 1.5 mm disc flat?
Symmetric light passes, proper backing, and no aggressive clamping. Thin parts remember every stress you put into them.
Why does the blast finish matter on a cover?
Blast and anodize are the visible surface of the instrument. Uniform media and parameters are what keep 50 discs looking like one part.
