From the picture I just viewed it looks like a bottom loading collate with the top of the spindle covered, unless it is some sort of a hinged cover that does not show well in the picture.

They also have a blurb that it is auto Z sensing.

Those two things make me ask how to burnish with that machine unless you can set the spindle to a very low pressure. If it senses on every cutter-down that is possible.

Right now it is still a very valid question to me.
