wcubed vise for Pocket NC

Just because I’m generally looking for workholding solutions for the Pocket NC, I recently picked up a vise designed for it from wcubed.co.

Unlike the stock vise that comes with the PNC, this has two movable aluminum jaws.  It can probably hold with greater force than the stock vise, since there is a larger contact area, although the screw mechanism doesn’t necessarily apply the force all that uniformly.  Also, since both jaws are movable, you have to take some care to either manually center things, or do some edgefinding, which isn’t terribly easy on a PNC.

What it does allow though, is clamping narrow things.  The stock vise bottoms out at around 0.5″.  This vise can go all the way down to 0.

That came in handy with some recent moteus servo parts that I wanted to do a “5-axis” style toolpath from 3/8″ thick bar stock.

Is it really that tall?

The vise provided plenty of clamping power to hold and machine at the tip of this awkwardly long bar.  This cut does chatter like crazy, but that’s about what you would expect.
