ABSTRACT:
A thin edge orifice disk is defined as a disk having a thickness to main dimension or diameter ratio of at least 1:80. The manufacturing of an accurately sized orifice in the disk is accomplished by means of a progressive die. One of the stations of the die provides a coining operation on the orifice. Such coining operation is adjustable by means of a micrometer adjustment.
