Dear colleagues, I ask for help.
For a very dirty spot on a grinder, I'm looking for something that looks like an electronic linear encoder with the following features:
-stroke 400+mm (16+ inches)
- resolution 0.5 µm or less
-accuracy is a difficult question The final accuracy should be within 2 μm, but the main thing is stability. If the stability is within 1 µm and the accuracy is 10 µm, then I will simply make a correction table using a laser interferometer
- degree of protection ip65 or so
The device I need should look like this electronic indicator: https://shop.mitutoyo.eu/pim/upload/mitutoyoData/image/bigweb/mit_2332____eps.png
Only with 16 inches of travel Another thing that this indicator should look like is an air cylinder with a linear encoder inside.
I understand perfectly well that this will not be a very cheap device, probably the price will be about $ 5,000
I've almost come to terms with the idea that I'll have to make this thing myself.
Something like a pneumatic cylinder, inside of which a linear guide and a linear encoder are fixed. Attached to the movable side of the linear guide is the linear encoder carriage and stem. Thus, when the rod moves, the carriage of the linear encoder moves, and the linear guide does not allow the rod to turn. The stem seal prevents a cloud of dust and coolant from getting inside and contaminating the linear encoder.
But I really don't want to spend a lot of time on it
