I'm fixing to buy a machine and I'm trying to get all my tooling nailed down. I have never done anything other than rigid tapping in a CNC vertical, so I am not sure how to use a compression tapping head system. -More specifically I don't know what I need.
Looking at the Tormach site, I see they offer a couple things. The first is the 31807 - Modular Tension/Compression Tapping Head Kit, and then there are the separate heads further down the page. One is labeled 32021 - TTS-ER20 Tension/Compression Tapping Head, and the other is labeled 32020 - TTS-ER16 Tension/Compression Tapping Head.
I am assuming that the last two I listed must have collets to work correctly?
Thanks
