How to use the Pocket NC Vise
The Pocket NC vise was designed to be super adjustable and have excellent grip. While it does not look like a traditional vise the function is the same. Dowel pins and/or set screws are used in place of jaws and are completely interchangeable. M4 set screws work like gripper jaws for roughing material and will work for a hardness of aluminum and anything softer. Dowel pins can be used for light finishing work. The pins can be adjusted in increments of 5 mm. The movable jaw has a travel of 6mm with 6+ mm of thread engagement.
Mounting the vise to the PocketNC mill is simple and precise. In combination with two ⅛” dowel pins, the vise is mounted with a M4x10 fastener. The user can choose 1 of 4 positions in 90 degree increments.
Here you can see the PocketNC vise mounted on the B axis table within Fusion 360.
The origin of the machine (G54 X0 Y0 Z0 A0) is represented as a pink dot centered on the table .885” above the surface. Material can be placed within Fusion 360 using the this table and vise setup to accurately represent the setup on the machine. You can find the Fusion file for the vise and table here.
Here is a representation of the Autodesk A logo being set up for machining. A lighter area represents the stock material that will need to be removed. The part should be adjusted in XY and Z to represent the desired end result. In the photo, centerline of the B axis is parallel with the centerline of the spindle, this is A 90 degrees. The movement of the rotational axis may be different than the user may imagine, users should take the time needed to understand how the axes move in relation to each other.
