Surfcom replacement part lead time

[[Jo...]]

Has anyone with a Surfcom had issues with the detector failing and had to deal with the lengthy lead time to get a replacement part? The lead time we were told is 2-6months for a replacement part which seems pretty crazy to me but Zeiss said that is normal for that part.
If you have run into this issue, can you provide insight on what your company did to help bridge the gap and inspect parts while having a machine down for months? We are a prototype heavy company and use it daily for inspecting tight tolerance threads, radii, and chamfers.
