I have a small vise in my CNC mill that when I tighten stock on parallels, raises the material approx .015"
I'm told that a good vise cams down when tightened.
I've also been told that banging the stock down while tightening is a normal procedure.
went to Busy Bee, they have several vises to choose from, some where Kurt type
All their vises exhibited the same if not worse raising of the stock problem.
So I have two questions, Is there a reasonable vise that holds the material down?
or is there a method that automatically zeros the Z axis upon touching the stock in program control
I would assume that the vise / stock would need to be isolated from ground and that the tool bit
would send a ground to the control, re zeroing the axis for each part.
Is this done? or what is the recommended way to do this, besides banging the stock down?
usually just using aluminum, but trying to do a consistently good job.
Thanks Peter
