HB/Z 129-1988 (English Version) PDF

Scope: This standard further quantifies and standardizes the accuracy of optical tool installation based on the methods and theories provided by the "Optical Tool Installation Rack" standard. For the purpose of calculating the mounting accuracy using the microcomputer-assisted optical tool method, the data were organized into a tree shape. The data provided by this standard are values that can be achieved when the instrument is normal and operated correctly. This standard applies to aircraft, rocket, and missile manufacturing industries. It is also suitable for shipbuilding, machine tools, heavy machinery, large motors, locomotives, vehicles, high-energy accelerators, large radar antennas, radio telescopes and other industries.
