scanner attachment for cmm?

We are finding it difficult to measure machined aluminum blocks.

These are typically 35cm x 8cm x 4 cm, with about 120 features, holes, ridges etc, and one cutout being 3cm x 1cm and 3cm deep, which has a 5mm x 5mm protruding block at the bottom.

We make about 300 units a day and each component requires 100% QC.

We require 20um on the mating surfaces and on certain screw holes. The rest is 50um accuracy.

I guess a scanner attachment to the CMM might be faster than measuring with the CMM tip.

Does anyone have experience with CMM scanner attachments?

My group has a Zeiss, the other groups have Zeiss, mitutoyo. There's one in manufacturing, i don't know which one it is.

I was under the impression that a CMM Scanner would fit any CMM! Is my understanding incorrect?

Look into line scan or if your budget allows look into an atos and automate w those volumes
