I need to convert a bunch of tiff (CMYK) images to png (RGB) to process them through a certain program, and then convert them back to tiff (CMYK) again.

As far as I know, both formats are lossless. So can I simply convert them using Photoshop with default parameters and not have any losses in quality? Or are there some details that I should know before doing so?

Simple answer: No.

Longer answer: You will not loose image data as such (They wont start to display compression artefacts etc), However in converting between CMYK and RGB then back, you will basically completely screw up the colours. As CMYK and RGB are not compatible colour spaces.
