PROBLEM
Machining and blind hole tapping a thin wall while maintaining a very strict flatness tolerance.
Parts go through a special paint process.
BGM SOLUTION
BGM engineers developed special tooling and fixtures to make sure the blind hole tapping is done correctly with little to no fall out.
QC designed a specific gage to check flatnes for the machine operators to do 100% inspection.
Engineers had to work directly with the painting supplier to develop a special masking process to provide 0 defects during painting.
