Hi..

The OPTIMUM BF20L has a z-travel of 280 mm.

How is this exactly calculated ?
If the drill-cutter head is down, does it touch the table ?

Suppose a cutter sticks 100 mm out of the cutter holder.
Does the distance between the cutter and the table then become 280 - 100 = 180 mm ?
Or will it be a little bit more then 180 mm ?
How much more ?

Thanks..
