Case Review
The washer’s OD must seat tightly into the bore, with exhaust grooves punched on both faces. Top and bottom edges get chamfered to prevent any gap, and a slot is added for gas escape. This part is machined from 6061 duralumin, 3 mm thick, with chamfered edges and grooves on both the upper and lower faces.
