Before deburring interior holes, what must be done to the assembly?

Before deburring interior holes in an assembly, it is important to first take the assembly apart. This is because deburring effectively removes sharp edges and burrs from the machined surfaces, which can be difficult to access if the assembly is still fully assembled.

By disassembling the parts, you ensure that you can reach all the inner surfaces safely and effectively without damaging other components. Additionally, it helps prevent any debris created during the deburring process from contaminating other areas of the assembly. This step is crucial for maintaining the integrity and safety of the overall assembly, particularly in aerospace applications where precision and cleanliness are paramount.

Taking the assembly apart allows for thorough inspection and proper treatment of each individual part, ensuring that the final assembly functions correctly without any obstructions or weaknesses caused by leftover burrs.
