Precision Machining of Beryllium

Chemical milling of 0.002” is performed to remove that damage. If high precision features are required thereafter, critical final lapping/grinding is performed in order to establish those features. Beryllium’s and Be-38AL’s fracture toughness value K 1c is 9 ksi in. The relationship between flaw sizes, fracture toughness and maximum stress are well understood for beryllium and designs are produced accordingly.
