A milling fixture in the form of a scroll lathe chuck with 2 piece jaws, integrated with the base.
Depending on the adaption, it can be used on milling machine tables, t-towers, drill tables, or surface grinders.
It has a mechanism drive from the front of the fixture, you can use a standard wrench with a spring or a ratchet knob with a cap.
The fixture is sealed against chips, the center by a cover, and the guides by extra teeth on the jaw.
It has two locating keys and 4 recesses for fastening screws to be fixed to the table/tower/pallet. It is possible to attach it by the flange of the fixture with toe clamps to the machine table.
The fixture is low profile, which is and advantage for machine tools with a short z-axis travel, because it does not limit the machine's movements like a chuck with a base.
When the profile is as low as possible, standard 3200 soft jaw blanks can be used and shaped accordingly.
