CASE STUDIES
Three parts that were harder than the drawing suggested.
Semiconductor work is judged after the part is installed, not when it leaves the shop. These are the problems that keep engineers up at night — flatness after anodizing, a seal that won't hold, and an obsolete part with no drawing.
A chamber flange that stayed flat through passivation
A Ø260 sealing face that has to stay flat through passivation — distortion removed before the finish cut.
380 holes, one flatness callout, and an anodize bath
380 holes at ±0.01 mm on a 320 mm plate, checked after black anodizing.
No drawing, no OEM support: reverse-engineering a feed-through housing
A worn sample becomes a model, a tooling plan and a fit-checked replacement.
Every program was run at a partner machine shop under our process control — we don't own the machines. Program details are anonymized and customer names are withheld under NDA; dimensions and lead times are the ones that decided the outcome.
