I’m wondering what work-holding strategies people use for blocks of aluminium.
I have the threaded table and on the table I use a sacrificial surface that I faced flat. I use this when milling large flat pieces where I have holes or similar features that can be used for clamping the aluminium to the bed.
However, if I am milling a billet with no holes I’d prefer to cut raw stock somewhere near to size so the edge contour is just cleaning up the part rather than milling it out of a bigger block and slotting all-around to cut the part loose. I have a couple of vices but don’t use them that often as I struggle with strategy for blocks that need an edge contour.
I notice with the ‘big’ machines folks will just clamp the block in the vice with parallels and then after milling the part and around the edges, flip the part and face off the extra 1/4" of stock. However, this strategy isn’t really doable on the Nomad due to the length of time to face off the extra material.
What’s your strategy?
