Question about Bridgeport quick change tool holders.

[l u k e]

A few years ago I was looking into picking up a Bridgeport Series 1 R2E4 cnc mill and and upgrading the control.

The mill came with a very large collection of quick change tool holders. I was wondering how the holders work? Are they collets or do they lock the cutter in position? (I really didn't look at them very closly at the time.)

What I was curious about was setting tool heights and weather or not the tool height was maintained between changes?

This is probably a stupid question, but I don't know, so I gotta ask.

The tool holder uses a collet to hold the tool, but there is a set screw type insert that you can screw in from the back of the collet and "lock" the bit in at a set height.

we set TLO everytime, but we rarely do repetative runs. My guess is that yes you can set the tool height once and it should hold it.

Thanks, that's what I needed to know...
