Machinists have a number of variables to consider when setting up devices for a machining operation. When it comes to cnc workholding, there are some major differences between holding a loosely toleranced duplicate part with a 10-minute cycle time and holding a tightly toleranced specialized part with a 10-hour cycle time.

Because of it's parallel facing jaws, a vice is perfect for holding square or rectangular items, but can be used to hold just about anything. Vises offer extremely high clamping forces, which are needed when milling tough materials. A low profile, 4-inch, cast iron drill press vise like the one shown below works well for firmly holding materials.

Milling Through Holes on Parts Held with a Vacuum Table. Another common problem associated with conventional vacuum tables is that when you cut through sheet material, you get a loss of vacuum. If open holes allow too much loss of vacuum and the parts let go, often damaging the cutting tool, the machined part and even the CNC equipment.
