Vises come in many
shapes and sizes. Those
shown in Figure 2 are just
a few examples. Normally,
you will size the vise to fit
your machine and part.
You can use a small
vise on a large machine,
but you cannot use a large
vise on a small machine.
Figure 3 shows a vise that
is too large for the MF70
Not only is there no
way to clamp the vise, the
weight could possibly
damage the MF70.
You are not limited to a
single vise. Two vises can
be used to hold long narrow stock as shown in Figure 4. If
machining the ends of the stock using a single vise, it
would chatter. By clamping it into two vises, it is held
securely on both ends.
In this article, I will be showing you how to attach and
tune the vise shown in Figure 5 to the MF70 micro CNC
that we built in the April-August 2014 issues (however, the
process is pretty much the same for any CNC machine). This
vise was designed specifically for the MF70.
While you need only a couple hand tools to attach the
vise to the table, there is one tool you must have to adjust
the vise properly. As a minimum, I recommend a dial
