Abstract
In a two station machining vise having a stationary, center jaw and movable opposing jaws, the interior of the vise body is totally enclosed to protect the working components from machining byproducts. The vise has a brake mechanism and an offset mechanism associated with one slide so that workpieces can be engaged and released sequentially. If the brake mechanism is not activated, the two movable jaws are moved simultaneously. With the brake mechanism engaged, one movable jaw is moved to position first and then the movable jaw having the brake and offset mechanisms connected therewith is subsequently moved into position. When the workpieces are to be released, the second movable jaw is first retracted the offset distance and then the first movable jaw must be completely retracted prior to any subsequent movement by the first movable jaw.
