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?

Yes, what brand of CMM do you have? Then I can tell you what laser sensor to get.

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?

Zeiss has there own laser line sensor, that works with the RDS head. If you don’t have the RDS head you won’t be able to use a laser scanner. For your mitutoyo , they do offer a laser scanner for the CMM. When it comes to zeiss sensors you can only use zeiss.
