Product Code:SAE MA1759
Title:Center Hole, Metric
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: This SAE Metric Aerospace Standard (MA) specifies the drawing requirements for center holes when center holes are required on the finished part. Center holes make it possible to install a part between bench or machine centers in the process of manufacturing. With such center holes, it is possible to: achieve center related runout requirements; and simplify manufacture and inspection of some revolution generated parts, namely those featuring multiple concentric diameters requiring several machining operations.
