Is it time for a CMM?



All, thank you in advance to for any input you can provide.

Our machine shop focuses on smaller parts (most <30mm max dimension), most having a number of bearing fits and bores to measure. We are currently getting on okay with our measuring microscope and hand tools but we are hoping to automate inspections and improve on the limitations of optical inspections.

I’ve included grabs of a few different parts that represent our measurement requirements. We are currently considering a Zeiss O-Inspect as the top contender. For some of the smallest features, the optical seems like a value-add.

Key Questions:

-For 1.5-2.0mm features (blind holes), should we be looking at small probes or optical measurement?

-Where are people getting the most value from the optical sensors?

-Are we better off with a non-optical CMM?

Thanks!
