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.
